-Fix improper usage of rand() in cpow2, cpow3, hypertile1, hypertile3D1, hypertile3D2, juliac, juliaq.
-Fix program crashing during density filtering on some Nvidia cards.
-hypertile3D1 was wrong.
-Parsing phoenix_julia when coming from Apophysis was wrong.
-Density filtering was freezing on certain Nvidia cards.
--Code changes
-Optimize juliac, npolar.
-Add a new function Crand() which behaves like the legacy C rand() which returns an integer between 0 and 32766, inclusive.
-Use RandBit() in some places.
-Remove Zeps() from vignette, it's not needed.
-Restructure OpenCL code for density filtering such that it does not hang after being compiled on some Nvidia cards, such as the gtx 1660. Remove barriers from conditionals where possible.
-Optimization and correction for hexaplay3D and hexnix3D.
-Major optimization on the GPU for flames which only have one xform, by skipping all random xform selection code.
-Changes to how xaos is "preserved" when adding new xforms, copying xforms and duplicating xforms.
--Duplicating xforms when no xaos is present in the flame now maintains not using xaos, and keeps all values as one.
--Duplicating xforms when xaos is present, will result in xaos rows and columns that are the same as the xforms being duplicated, with the new row and column area having values of 1.
--Duplicating xforms when xaos is present, while Control is pressed, will result in xaos rows and columns that have values of 0, with the new row and column area having values of 1.
---Copying xforms has the same behavior as duplicating with Control pressed.
--Bug fixes
-hexaplay3D, hexnix3D and post_smartcrop were wrong on the GPU because they are the rare variations which preserve state between iterations.
-Changing the sub batch size would improperly wrong the wrong number of iterations.
--Code changes
-Some functions in Affine2D made const.
-Change in the index at which points and variation state are preserved between kernel calls.
-Some arguments in some member functions of GLEmberController made const.
-Improve performance in the following variations: cpow2, dc_cube, julia3d, julia3dz, julian2, log_db, nblur, npolar, waffle, wavesn, xtrb.
--Code changes
-Rand range now uses multiply + shift rather than modulo.
-Add new variations waves22, waves23, waves42, waves3 and waves4 from user tatasz.
-Add new stylesheet called lightdark.qss which gives a more modern look to the dark theme. Started by Michel Mastriani (triptychaos).
--Included in the qmake and Wix installers.
--Code changes
-Add a new C# project that attempts to convert Apophysis plugins to Fractorium style Variation classes. It's not entirely perfect, but gets most of the job done much more quickly than doing so manually.
-Remove unused OpenCL functions from variations: elliptic, poincare, mask, bMod, bSwirl, bTransform, bCollide, farblur, popcorn2_3D, falloff, falloff2, falloff3, crackle2, waves2b, hypercrop, depth_gaussian2, depth_sine, depth_sine2, dust, asteria, vibration, vibration2, arctanh, smartshape, squares, starblur2, Truchet,.
-Add code in EmberTester to automatically detect such unused functions.
-Show common folder locations such as documents, downloads, pictures in the sidebar in all file dialogs.
-Warning message about exceeding memory in final render dialog now suggests strips as the solution to the problem.
-Strips now has a tooltip explaining what it does.
-Allow more digits in the spinners on the color section the flame tab.
-Add manually adjustable size spinners in the final render dialog. Percentage scale and absolute size are fully synced.
-Default prefix in final render is now the filename when doing animations (coming from sequence section of the library tab).
-Changed the elliptic variation back to using a less precise version for float, and a more precise version for double. The last release had it always using double.
-New applied xaos table that shows a read-only view of actual weights by taking the base xform weights and multiplying them by the xaos values.
-New table in the xaos tab that gives a graphical representation of the probability that each xform is chosen, with and without xaos.
-Add button to transpose the xaos rows and columns.
-Add support for importing .chaos files from Chaotica.
--Pasting back to Chaotica will work for most, but not all, variations due to incompatible parameter names in some.
-Curves are now splines instead of Bezier. This adds compatibility with Chaotica, but breaks it for Apophysis. Xmls are still pastable, but the color curves will look different.
--The curve editor on the palette tab can now add points by clicking on the lines and remove points by clicking on the points themselves, just like Chaotica.
--Splines are saved in four new xml fields: overall_curve, red_curve, green_curve and blue_curve.
-Allow for specifying the percentage of a sub batch each thread should iterate through per kernel call when running with OpenCL. This gives a roughly 1% performance increase due to having to make less kernel calls while iterating.
--This field is present for interactive editing (where it's not very useful) and in the final render dialog.
--On the command line, this is specified as --sbpctth for EmberRender and EmberAnimate.
-Allow double clicking to toggle the supersample field in the flame tab between 1 and 2 for easily checking the effect of the field.
-When showing affine values as polar coordinates, show angles normalized to 360 to match Chaotica.
-Fuse Count spinner now toggles between 15 and 100 when double clicking for easily checking the effect of the field.
-Added field for limiting the range in the x and y direction that the initial points are chosen from.
-Added a field called K2 which is an alternative way to set brightness, ignored when zero.
--This has no effect for many variations, but hs a noticeable effect for some.
-Added new variations:

--Bug fixes:
-Bounds sign was flipped for x coordinate of world space when center was not zero.
-Right clicking and dragging spinner showed menu on mouse up, even if it was very far away.
-Text boxes for size in final render dialog were hard to type in. Same bug as xform weight used to be so fix the same way.
-Fix spelling to be plural in toggle color speed box.
-Stop using the blank user palette to generate flames. Either put colored palettes in it, or exclude it from randoms.
-Clicking the random palette button for a palette file with only one palette in it would freeze the program.
-Clicking none scale in final render did not re-render the preview.
-Use less precision on random xaos. No need for 12 decimal places.
-The term sub batch is overloaded in the options dialog. Change the naming and tooltip of those settings for cpu and opencl.
--Also made clear in the tooltip for the default opencl quality setting that the value is per device.
-The arrows spinner in palette editor appears like a read-only label. Made it look like a spinner.
-Fix border colors for various spin boxes and table headers in the style sheet. Requires reload.
-Fix a bug in the bwraps variation which would produce different results than Chaotica and Apophysis.
-Synth was allowed to be selected for random flame generation when using an Nvidia card but it shouldn't have been because Nvidia has a hard time compiling synth.
-A casting bug in the OpenCL kernels for log scaling and density filtering was preventing successful compilations on Intel iGPUs. Fixed even though we don't support anything other than AMD and Nvidia.
-Palette rotation (click and drag) position was not being reset when loading a new flame.
-When the xform circles were hidden, opening and closing the options dialog would improperly reshow them.
-Double click toggle was broken on integer spin boxes.
-Fixed tab order of some controls.
-Creating a palette from a jpg in the palette editor only produced a single color.
--Needed to package imageformats/qjpeg.dll with the Windows installer.
-The basic memory benchmark test flame was not really testing memory. Make it more spread out.
-Remove the temporal samples field from the flame tab, it was never used because it's only an animation parameter which is specified in the final render dialog or on the command line with EmberAnimate.
--Code changes:
-Add IsEmpty() to Palette to determine if a palette is all black.
-Attempt to avoid selecting a blank palette in PaletteList::GetRandomPalette().
-Add function ScanForChaosNodes() and some associated helper functions in XmlToEmber.
-Make variation param name correction be case insensitive in XmlToEmber.
-Report error when assigning a variation param value in XmlToEmber.
-Add SubBatchPercentPerThread() method to RendererCL.
-Override enterEvent() and leaveEvent() in DoubleSpinBox and SpinBox to prevent the context menu from showing up on right mouse up after already leaving the spinner.
-Filtering the mouse wheel event in TableWidget no longer appears to be needed. It was probably an old Qt bug that has been fixed.
-Gui/ember syncing code in the final render dialog needed to be reworked to accommodate absolute sizes.
-Add buttons to copy and paste affine transforms.
-Show xform names on the column headers of the xaos table.
-Add a color-coded third column to the variations tree which shows any properties of each variation which are non-standard.
-Draw a transparent circle over hovered xforms.
-Change how xforms respond to dragging. Rotate only is now the default, and scale will only happen with shift.
--Optionally do scale and rotate when holding shift, via a setting in the options dialog.
--Bug fixes
-Snapping when dragging was wrong sometimes.
-The program would very rarely crash on startup due to some values being in an uninitialized state.
--Code changes
-Change almost every variation to use fma() in OpenCL when doing computations of the form a * b + c. This provides a slight speedup, mostly in double precision mode.
-Also apply fma() to affine calcs.
-Cleanup of OpenGL affine drawing code.
-Separate the concept of hovering and selecting xforms.
-Give tabs a height of 4px in the qss files. Looks a little large on 4k screens, but just right on HD screens which are much more common.
-Allow for styling of zero and non-zero variation tree nodes via qss.
-Allow for toggling whether to interpolate between colors in the palette editor, or to do hard cuts between colors.
-Allow for adjusting spinner values with the + = or up arrow keys to increase, and - _ or down arrow keys to decrease.
-Allow for responding to global presses of + = and - _ to cycle up or down to specify which xform is set as the current one.
-Allow for adding "layers" via xaos which will add a user-specified number of xforms, and set certain xaos values to 0 or 1.
-Add a new menu item under the Edit menu to copy the OpenCL iteration kernel source to the clipboard.
-Show text on the status bar which indicates that an OpenCL kernel compilation is taking place.
-Show xform name on xform combo box when expanded. Adjust size to fit all names.
-Draw post affine circles using dashed lines.
-Prevent QSS dialog from styling its editor, which makes it easier to see text when creating styles which have custom colors for text boxes.
--Bug fixes
-Fix up some table layouts which seemed to have regressed/decayed over time for reasons unknown.
-Using undo/redo would create a new flame in the library every time.
-Solo was not being preserved when using undo/redo.
--Code changes
-Make the solo flag be a part of the flame data now.
-Fix some tabification in the OpenCL code for EllipticVariation.
-Fix tabification in the varState code for OpenCL.
-Add an event called m_CompileBegun to RendererCL that is called right before an OpenCL compile is begun.
--This required making RendererCLBase not a pure virtual base class. Member functions just return defaults.
-Filter key presses on main window to only process the third one. This is due to Qt triggering three events for every key press.
-The palette preview table was installing an event filter for seemingly no reason. Remove it.
-Mark certain virtual functions as override in SpinBox and DoubleSpinBox.
-Add two new variations, hyperbolic and hypershift2.
-Allow for animating final xforms.
-More detailed diagnostics when any action in the OpenCL renderer fails.
-Allow for creating an OpenCL renderer which does not share a texture with the main window, and instead manually copies its final output image from GPU to CPU then back to GPU.
--Bug fixes
-Text was not properly being copied out of the Info | Bounds text box.
--Code changes
-Remove Renderer::AccumulatorToFinalImage(v4F* pixels, size_t finalOffset), it's no longer needed or makes sense.
-Controllers no longer keep track of shared status, it's kept inside the renderers.
-Make getter functions in FractoriumOptionsDialog be public.
-Support 4k monitors, and in general, properly scale any monitor that is not HD.
-Allow for a spatial filter of radius zero, which means do not use a spatial filter.
-Add new variations: concentric, cpow3, helicoid, helix, rand_cubes, sphereblur.
-Use a new method for computing elliptic which is more precise. Developed by Discord user Claude.
-Remove the 8 variation per xform limitation on the GPU.
-Allow for loading the last flame file on startup, rather than randoms.
-Use two different default quality values in the interactive renderer, one each for CPU and GPU.
-Creating linked xforms was using non-standard behavior. Make it match Apo and also support creating multiple linked xforms at once.
--Bug fixes
-No variations in an xform used to have the same behavior as a single linear variation with weight 1. While sensible, this breaks backward compatibility. No variations now sets the output point to zeroes.
-Prevent crashing the program when adjusting a value on the main window while a final render is in progress.
-The xaos table was inverted.
--Code changes
-Convert projects to Visual Studio 2017.
-Change bad vals from +- 1e10 to +-1e20.
-Reintroduce the symmetry tag in xforms for legacy support in programs that do not use color_speed.
-Compiler will not let us use default values in templated member functions anymore.
--Added panorama1 and panorama2 variations.
Bug fixes:
--crackle had a bug with Nvidia GPUs.
Code changes:
--crackle now uses real_t* for cache rather than real2. This is what was causing the bug.
--Make the local offsets array used in crackle a precalc since it's the same for all. This reduces register pressure.
--Get rid of all usages of real3, just to be safe since Nvidia doesn't like them.
--#define TOTAL_GLOBAL_SIZE_END in the OpenCL iteration kernel just for debugging purposes to see how large the parvars buffer is.
-Attempt to fix several OpenCL build errors that were occurring on Mac.
--Code changes
-Improve the coloring code during final accum by getting rid of the last remnants of unnecessary scaling to 255 from flam3.
-Begin work of supporting 16bpc on the GPU.
--User changes
-dark.qss is now per-OS.
-Properly set/reload palette when coming from the palette editor. The latter must be done if they've modified the current palette even if they've clicked cancel.
--Bug fixes
-Make the following variations safer by using Zeps(): conic, bipolar, edisc, whorl, tan, csc, cot, tanh, sech, csch, coth, auger, bwraps, hypertile3d, hypertile3d1, ortho, poincare, rational3, barycentroid, sschecks, cscq, cschq, scry_3D, splitbrdr, hexcrop, nblur, crob.
-Fix bug enabling/disabling overwrite button in palette editor.
-Small optimization for gdoffs, use precalcAtanYX.
-Properly propagate z through circlesplit, cylinder2 and tile_log variations.
-Some values in truchet_fill could've been NaN.
--Code changes

-Allow toggling display of image, affines and grid.
-Add new variations: cylinder2, circlesplit, tile_log, truchet_fill, waves2_radial.
--Bug fixes
-cpow2 was wrong.
-Palettes with rapid changes in color would produce slightly different outputs from Apo/Chaotica. This was due to a long standing bug from flam3.
-Use exec() on Apple and show() on all other OSes for dialog boxes.
-Trying to render a sequence with no frames would crash.
-Selecting multiple xforms and rotating them would produce the wrong rotation.
-Better handling when parsing flames using different encoding, such as unicode and UTF-8.
-Switching between SP/DP didn't reselect the selected flame in the Library tab.
--Code changes
-Make all types concerning palettes be floats, including PaletteTableWidgetItem.
-PaletteTableWidgetItem is no longer templated because all palettes are float.
-Include the source colors for user created gradients.
-Change parallel_for() calls to work with very old versions of TBB which are lingering on some systems.
-Split conditional out of accumulation loop on the CPU for better performance.
-Vectorize summing when doing density filter for better performance.
-Make all usage of palettes be of type float, double is pointless.
-Allow palettes to reside in multiple folders, while ensuring only one of each name is added.
-Refactor some palette path searching code.
-Make ReadFile() throw and catch an exception if the file operation fails.
-A little extra safety in foci and foci3D with a call to Zeps().
-Cast to (real_t) in the OpenCL string for the w variation, which was having trouble compiling on Mac.
-Fixing missing comma between paths in InitPaletteList().
-Move Xml and PaletteList classes into cpp to shorten build times when working on them.
-Remove default param values for IterOpenCLKernelCreator<T>::SharedDataIndexDefines in cpp file.
-Change more NULL to nullptr.
-crackle is now 5-10 times faster as a result of using cached values as is done on the CPU. These were previously omitted due to a bug elsewhere in the code that was erroneously attributed to the crackle caching mechanism.
-Report precision in command line programs.
-Edits will not save back to the file in memory on render completion when preview renderer is running.
--Bug fixes
-dc_perlin was crashing on Nvidia when using SP.
-Duplicate images were randomly getting added to the file in memory.
-Crash when opening an Xml with less than 2 flames in it.
--Code changes
-Use raw array of floats in OpenCL for perlin noise, rather than float3/double3.
-Add some default cases to dc_perlin.
-Redo singleton pattern yet again. Deriving from a templated Singleton<T> class was creating a separate instance per module. Now only one instance of each type will ever be created and it will be wrapped in a shared_ptr which guarantees its deletion as main() exits.
-Better handling of crossed min/max DE filter values on the GUI.
-Changes to spatial and density filter values will no longer restart the entire render.
-Support reading cam_zoom from xml as zoom since JWildfire uses cam_zoom.
-Change drag n drop behavior: the default is now to append, hold Ctrl to overwrite.
-Set max value of zoom to 25 because it will crash with values around 28 or 29 due to numeric overflow when scaling quality.
-Update links in About Dialog.
-Rename some controls in Options Dialog.
-Move the color curves control to the Palette tab.
--Bug fixes
-Remove extra space in info tree text when dealing with a linked xform.
-Update summary xform name field whenever xform name changes.
-Get rid of selection border on summary tab xform tree cells.
-Only add variations from Xml that have a non-zero weight. There seemed to be spurious flattens coming from Apo with a weight of 0.
--Code changes
-Gutters are now a fixed size of 8 * supersample.
-Use stl data() member to get pointer to first element instead of &vec[0].
-Eliminate extra calls in renderer to ComputeBounds(), CreateSpatialFilter() and CreateTemporalFilter() to only be done at the start of a render.
-Another attempt at vectorizing LogScaleDensityFilter(). Vectorizes, but not sure if it helps.
-Some other loop optimizations in Renderer.
-No longer check temporal samples in response to some control changes, they are always 1 in the interactive renderer.
-Fix crash when using Lanczos2 filter with color curves due to negative numbers. Fix by passing abs() of first argument to pow() in Renderer::GammaCorrection().
-Fix crash in hexes with SP. Rounding error caused out of bounds index.
-Split VariationList into .h/cpp files.
--Make VariationList.cpp the only place where the variations files are included from. This speeds up the build, but variations can no longer be directly instantiated.
--Variations are no longer exported.
-Add variations changes to the list of functionality that can be applied to all xforms using the Select tab.
-Allow for graphical affine adjustments to apply to multiple selected xforms.
-Slight optimization of the pie variation.
-Undo state is only saved when the render completes and the mouse buttons are released. This helps avoid intermediate steps for quickly completing renders while dragging.
-Add some keyboard shortcuts for toolbar and menu items.
-Make info tab tree always expanded.
--Bug fixes
-Make precalcs for all hypertile variations safer by using Zeps() for denominators.
-Changing the current xform with more than one selected would set all xform's color index value that of the current one.
-Use hard found palette path information for randoms as well.
-OpenCL build and assignment errors for Z value in epispiral variation.
-Unitialized local variables in hexaplay3D, crob, pRose3D.
--Code changes
-Change static member variables from m_ to s_.
-Get rid of excessive endl and replace with "\n".
-Remove old IMAGEGL2D define from before Nvidia supported OpenCL 1.2.
-Remove old CriticalSection code and use std::recursive_mutex.
-Make Affine2D Rotate() and RotateTrans() take radians instead of angles.
-More C++11 work.
-General cleanup.
-Allow for pausing the renderer in the main window. This makes is more efficient when entering many parameters, such as when following a tutorial.
-Add support for new variations: erf, gamma, jac_cn, jac_dn, jac_sn, logDB, pressure_wave, pRose3D, splits3D, w, waves2b, x, xerf, y, z.
-Inform user of the start and stop of file parsing in EmberAnimate because the files could potentially be very large.
-Move the follwing fields to a new table called Animation: Interpolation, Affine Interpolation, Temporal Samples, Temporal Filter Width, Temporal Filter Type.
-These currently have no effect on the interactive renderer and instead are used when running flames through EmberGenome to generate sequences, and then animating them in Fractorium or EmberAnimate.
-Add new parameter overrides for EmberRender and EmberAnimate which directly assign values to all flames being rendered, rather than scale:
--quality
--demin
--demax
--Bug fixes
-Left pad instead of right pad names of sequence outputs from EmberGenome.
-Unique file naming was broken for files which already had an underscore in them.
-Properly report that png is the default format of EmberRender and EmberAnimate output instead of erroneously claiming it was jpg.
-Make command line programs search these folders in this order for the palette file:
./
~/.fractorium
~/.config/fractorium
/usr/share/fractorium
/usr/local/share/fractorium
-Fix possible bad values in hexes.
-Better assignment of Z variables.
-Fix boarders due to use of poorly implemented rint() function from flam3. Use std::rint() now.
-wedge_sph was completely wrong due to having accidentally swapped the mapping of two parameters.
-Make juliascope juliascope_power parameter be of type REAL_NONZERO since it's used as a denominator.
-Make Z assignment compatible with the originals in:
-arch, bcircle, bCollide, bent, bent2, bisplit, blob, blur_linear, blur_square, bMod, boarders, boarders2, bSwirl, bTransform, butterfly, cardioid, cell, circleblur, circlize, circlize2, circus, collideoscope, cos, cosine, cosh, coth, cpow, cpow2, crescents, cropn, csc, csch, curl, curve, dc_gridout, deltaa, diamond, disc2, eclipse, eCollide, edisc, eJulia, elliptic, eMod, eMotion, ennepers, epispiral, ePush, eRotate, eScale, eSwirl, ex, exp, expo, exponential, fan, fdisc, fibonacci, fibonacci2, fisheye, flipcircle, flipy, flower, flux, funnel, glynnia, GlynnSim1, GlynnSim2, GlynnSim3, gridout, handkerchief, heart, hole, idisc, julia, julian2, juliaNab, kaleidoscope, lazyTravis, Lissajous, mask, MobiusN, mobius_strip, modulus, murl, murl2, npolar, ortho, oscilloscope, parabola, perspective, petal, phoenix_julia, pie (was also inconsistent between cpu and gpu), poincare, popcorn, popcorn2, power, pow_block, rational3, rays, rblur, rings, rippled, roundspher, sec, secant2, sigmoid, sin, sineblur, sinh, sinusgrid, sphericaln, spiralwing, spirograph, split, squarize, squirrel, squish, sschecks, starblur, stripes, stwin, super_shape, tan, tancos, tangent, tanh, TwinTrian, twoface, unpolar, waves, wavesn, wedge_julia, whorl, xheart, zblur, zscale.
--Code changes
-Generalize Variation::PrecalcHelper() and rename to PrePostPrecalcHelper().
--Do the same for the OpenCL version and rename it PrePostPrecalcOpenCLString().
-Rename Variation::m_AssignType to m_PrePostAssignType since it's only relevant to pre/post variations.
-Add the following modes to synth:
-MODE_SHIFTNSTRETCH 14
-MODE_SHIFTTANGENT 15
-MODE_XMIRROR 17
-MODE_XYMIRROR 18
-MODE_SPHERICAL2 19
-Clamp synth_mode, synth_*_type and synth_*_layer to valid values.
--Bug fixes
-synth was broken due to passing synth_mode to Interpolate, rather than synth_smooth.
-Fix bad include and link path in EmberAnimate project.
-Add post_smartcrop.
--Bug fixes
-Fix bug in crackle.
-Wrong point assignment in hexaplay3D, hexnix3D.
-Improper Z assignment in rblur.
-Fix inconsistency with original in circlecrop.
-Put EMBER_ROOT bakc to ./../../../ in default.pri. This is TBD.
--Code changes

-Convert some if/else statements in filter classes to case statements.
-Add overloaded stream operators to print various enums.
-Optimize crob, nBlur.
-Fix weird assignment statement in falloff3.
-Cleanup in VarFuncs::SimplexNoise3D().
-Replace fabs() with std::abs().
-General cleanup.
-Convert all enums to class enum to be consistent with C++11 style.

-Allow for highlight power of up to 10. It was previously limited to 2.
--Bug fixes
-Direct color calculations were wrong.
-Flattening was not applied to final xform.
-Fix "pure virtual function call" error on shutdown.
--Code changes
-Allow for array precalc params in variations by adding a size member to the ParamWithName class.
-In IterOpenCLKernelCreator, memcpy precalc params instead of a direct assign since they can now be of variable length.
-Add new file VarFuncs to consolidate some functions that are common to multiple variations. This also contains texture data for crackle and dc_perlin.
-Place OpenCL versions of these functions in the FunctionMapper class in the EmberCL project.
-Add new Singleton class that uses CRTP, is thread safe, and deletes after the last reference goes away. This fixes the usual "delete after main()" problem with singletons that use the static local function variable pattern.
-Began saving files with AStyle autoformatter turned on. This will eventually touch all files as they are worked on.
-Add missing backslash to CUDA include and library paths for builds on Nvidia systems.
-Add missing gl.h include for Windows.
-Remove glew include paths from Fractorium, it's not used.
-Remove any Nvidia specific #defines and build targets, they are no longer needed with OpenCL 1.2.
-Fix bad paths on linux build.
-General cleanup.
-Add new variations: bubbleT3D, crob, hexaplay3D, hexcrop, hexes, hexnix3D, loonie2, loonie3, nBlur, octapol and synth.
-Allow for pre/post versions of dc_bubble, dc_cylinder and dc_linear whereas before they were omitted.
-When saving a file with multiple embers in it, detect if time values are all the same and if so, start them at zero and increment by 1 for each ember.
-Allow for numerous quality increases to be coalesced into one. It will pick up at the end of the current render.
-Show selection highlight on variations tree in response to mouse hover. This makes it easier to see for which variation or param the current mouse wheel action will apply.
-Make default temporal samples be 100, whereas before it was 1000 which was overkill.
-Require the shift key to be held with delete for deleting an ember to prevent it from triggering when the user enters delete in the edit box.
-This wasn't otherwise fixable without writing a lot more code.
--Bug fixes
-EmberGenome was crashing when generating a sequence from a source file with more than 2 embers in it.
-EmberGenome was improperly handling the first frame of a merge after the last frame of the loop.
-These bugs were due to a previous commit. Revert parts of that commit.
-Prevent a zoom value of less than 0 when reading from xml.
-Slight optimization of the crescents, and mask variations, if the compiler wasn't doing it already.
-Unique file naming was broken because it was looking for _# and the default names ended with -#.
-Disallow renaming of an ember in the library tree to an empty string.
-Severe bug that prevented some variations from being read correctly from params generated outside this program.
-Severe OpenCL randomization bug. The first x coordinates of the first points in the first kernel call of the first ember of a render since the OpenCL renderer object was created were not random and were mostly -1.
-Severe bug when populating xform selection distributions that could sometimes cause a crash due to roundoff error. Fix by using double.
-Limit the max number of variations in a random ember to MAX_CL_VARS, which is 8. This ensures they'll look the same on CPU and GPU.
-Prevent user from saving stylesheet to default.qss, it's a special reserved filename.
--Code changes
-Generalize using the running sum output point inside of a variation for all cases: pre, reg and post.
-Allow for array variables in variations where the address of each element is stored in m_Params.
-Qualify all math functions with std::
