--Bug fixes
-File saving was broken.
--Code changes
-File saving and opening dialogs were shared between a single object which was causing trouble. Make them all use their own objects.
-Add a button to swap the pre and post affine values for all selected xforms.
--Bug fixes
-Remove the ability to change spinner values with +=-=, it was conflicting with other things and added no real value.
-All file dialog opening in Linux would freeze. No longer using native file dialogs, they are broken.
-Set default open path to the desktop if there is no settings file present, which will be the case on the first run.
-Amphibole_Supergroup.ugr palette had an invalid character in two of the palette names.
--Code changes
-Change some table header padding styles to work with new Qt. Qss reload is required.
-Ensure the open folder path setting always has a valid string in it before opening a folder.
-Add new palettes from user Rubydeva.
--Bug fixes
-Avoid an occasional divide by zero in the OpenCL renderer when using the interactive editor.
--Code changes
-Use exact comparisons in IsID() and IsZero() in Affine2D.
-When testing for bad point values while iterating, only test for NaN now.
-For rendering with OpenCL on the command line and in the final render dialog, use an optimized kernel that does a direct assignment for any affines which are ID.
-Further work on the About box.
--Change qss files to make the text box in the About box be the same color as the one in the style dialog, so the link text is easier to see.
--This requires reloading the qss file.
--Bug fixes
-Pre/post assign method was wrong for Sphereblur, Concentric, RandCubes and PixelFlow.
--Code changes
-Make Hypershift2 use MwcNextRange() instead of MwcNext() %.
-Add m_HasPre to Xform similar to m_HasPost, to skip application of the affine if it's the ID matrix (in this case just assign the input x and y points). This gives a 5% speedup.
-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.

-Density filtering progress bar in final render dialog did not update if only log scaling was being used.
--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
-Make most installation files read only.
-Qualify many calls with std:: to ensure they're not colliding with glm::
-Use auto in more places.
--Bug fixes
-Fix crash when opening palette editor with a flame whose palette specifies no originating file.
--Code changes
-Revert font changes, only use qss for these now.
--User changes
-Make all fonts be MS Shell Dlg 2. This will require reloading dark.qss if users are already using it.
-Limit size of the left side of the palette editor.
-Disable create from image buttons in the palette editor when working on a fixed palette.
--Bug fixes
-The following variations were wrong: coshq, cothq.
-During iteration, the color index could become nan if all xform color speeds were negative. This could lead to bad results on the GPU. Fix to check for nan. Minimal speed difference.
--Code changes
-Make the following variations safer by using Zeps(): sinq, sinhq, secq, sechq, tanq, tanhq, cosq, coshq, cotq, cothq, cscq, cschq, estiq.
-Always pass -cl-no-signed-zeros -cl-denorms-are-zero to kernel compiles for both single and double.
-Flush all denormals to zero for all executable programs. This will likely lead to a speedup for badly behaving programs.
-Fix strange spurious crash in library tab when switching between SP and DP.
-Compensate for severe Qt bug where dragging and dropping disjoint items in the Library tree would resort the dropped items in special situations.
-Move Info.plist to Data folder.
-Ensure RTTI is included in build.
-Add darker versions of .png icons.
-Add a palette editor.
-Add support for reading .ugr/.gradient/.gradients palette files.
-Allow toggling on spinners whose minimum value is not zero.
-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().

-Remove default param values for IterOpenCLKernelCreator<T>::SharedDataIndexDefines in cpp file.
-Change more NULL to nullptr.
--User changes
-Add many tooltips to help clarify functionality.
-Select multiple flames in library for del/move. Still only one allowed to be set as the current.
-Show checkbox for current flame. Remember this is not necessarily what's selected.
-User can now drag a square to select xforms, which keeps in sync with checkboxes.
-Remove --nframes from command line. Replace with new params: --loopframes, --interpframes, --interploops.
-Add two new options to EmberGenome: --cwloops --cwinterploops to specify whether rotation should go clockwise instead of the default counter clockwise.
-Add these to Fractorium as checkboxes.
-Apply All now also works for toggling animate flag on xforms.
-Options dialog now allows user to set whether double click toggles spinners, or right click does.
--Bug fixes
-Selecting final and non-final xforms, and then dragging the non-final did not drag the final with it.
-Selecting all xforms when a final was present, then deleting crashed the program.
-Remove support for ppm files in the command line programs, it's an outdated format.
-Switching between SP and DP kept reapplying the palette adjustments.
--Code changes
-Move build system to Visual Studio 2015 and Qt 5.6.
-SSE used during addition of points to the histogram.
-Remove last remnants of old flam3 C code and replace with C++.
-Remove unused code involving tbb::task_group.
-Make settings object a global shared_ptr singleton, so it doesn't have to be passed around.
-Highlight power is now on by default.
-Allow for adjustments on the Flame tab to apply to all open flames in the file.
-Add two new buttons to the color tab to randomize and toggle the xform color indices.
-Remove the --strip option from EmberGenome. It was useless and was likely just a carry over from flam3 during its early debugging stages when testing strips.
-Make randoms in EmberGenome have default dimensions of 1920 x 1080.
-Prevent --inter and --rotate in EmberGenome from rotating backward before the first flame since it doesn't really make sense.
-Ensure every loaded flame has at least one xform in it.
-Change dark.qss to hide dotted selection outline around checkboxes. Users must reload it to take effect.
--Bug fixes
-The saving of last.flame during editing was appending the file when it should have been replacing.
-It was impossible for EmberGenome to create a random flame. It can now be done by specifying no arguments: EmberGenome.exe
-Crossing in EmberGenome was not logging the performed actions to the edit Xml tag.
-Apply sub batch size and fuse count to template files used on the command line.
-Use new default filter types with template files.
--Code changes
-Use cerr in SheepTools instead of cout.
-Set m_SubBatchSize and m_FuseCount to default values in Ember::Clear().
-Clean up some command line options text formatting.
-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.
-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().
