-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 support for Exr files which use 32-bit floats for each RGBA channel. Seems to come out too washed out.
--Allow for clearing an individual color curve.
--Allow for saving multiple image types in EmberRender and EmberAnimate. All writes are threaded.
--Remove --bpc command line argument. Add format png16 as a replacement.
--Remove --enable_jpg_comments and --enable_png_comments command line arguments, and replace them with --enable_comments which applies to jpg, png and exr.
--Add menu items to variations and affine spinners which allow for easy entry of specific numeric values like pi.
--Make final render dialog be wider rather than so tall.
Bug fixes:
--Fix some OpenCL compile errors on Mac.
--Remove ability to save bitmap files on all platforms but Windows.
Code changes:
--New dependency on OpenEXR.
--Allow Curves class to interact with objects of a different template type.
--Make m_Curves member of Ember always use float as template type.
--Set the length of the curves array to always be 2^17 which should offer enough precision with new 32-bit float pixel types.
--Set pixel types to always be 32-bit float. This results in a major reduction of code in the final accumulation part of Renderer.h/cpp.
--Remove corresponding code from RendererCL and FinalAccumOpenCLKernelCreator.
--Remove Transparency, NumChannels and BytesPerPixel setters from Renderer.h/cpp.
--Add new global functions to format final image buffers and place all alpha calculation and scaling code in them.
--Blending is no longer needed in OpenGLWidget because of the new pixel type.
--Make new class, AffineDoubleSpinBox.
--Attempt to make file save dialog code work the same on all OSes.
--Remove some unused functions.
-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.
-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::
-No longer use our own Clamp() in OpenCL, instead use the standard clamp().
-Redesign how functions are used in the variations OpenCL code.
-Add tests to EmberTester to verify some of the new functionality.
-Place more const and override qualifiers on functions where appropriate.
-Add a global rand with a lock to be used very sparingly.
-Use a map instead of a vector for bad param names in Xml parsing.
-Prefix affine interpolation mode defines with "AFFINE_" to make their purpose more clear.
-Allow for variations that change state during iteration by sending a separate copy of the ember to each rendering thread.
-Implement this same functionality with a local struct in OpenCL. It's members are the total of all variables that need to change state within an ember.
-Add Contains() function to Utils.h.
-EmberRender: print names of kernels being printed with --dump_kernel option.
-Clean up EmberTester to handle some of the recent changes.
-Fix various casts.
-Replace % 2 with & 1, even though the compiler was likely doing this already.
-Add new file Variations06.h to accommodate new variations.
-General cleanup.
-Add Simon Detheridge's name to the About Box.
--Bug fixes
-Fix bug in OpenCL atomic string, which is never used.
-Wrong hist and accum allocation size in RendererCL when using float-only buffers now.
-Move some kernel initialization to a place where it's done once per render, rather than on every interactive iter chunk.
--Code changes
-Make ConvertCarToRas() just assign to the member rather than return a struct.
-Make kernel string accessor functions in IterOpenCLKernelCreator, FinalAccumOpenCLKernelCreator and DEOpenCLKernelCreator be const and return a const string reference.
-Don't include atomic string unless locking on the GPU, which is never.
-Remove Hue as a saved parameter, as well as animation parameters associated with it. It's now a GUI-only field that is never saved.
-Make histogram, density filter buffer, and all associated fields always float, even when using double. In that case, only the iteration calculations are now double. Suggested by Thomas Ludwig.
-Print all three kernels in EmberRender when the --dump_kernel option is specified.
-Apply variations filter to randoms.
--Bug fixes
-Fix bug where hue was not being preserved when switching controllers and embers. Very hard to repro bug, but mostly overcome by eliminating hue as a saved parameter.
--Code changes
-De-templatized DEOpenCLKernelCreator and FinalAccumOpenCLKernelCreator. They now just take a bool as a parameter to specify double precision.
-To accommodate the buffers being float, introduce a new #define types in EmberCL called real4_bucket, and real4reals_bucket.
-Density and spatial filtering structs now use this type.
-ConvertDensityFilter() and ConvertSpatialFilter() no longer return a value, they just assign to the member.
Add Curves.h, and CurvesGraphicsView.h/cpp to support bezier color curves.
Add Curves member to Ember.
Add curves capability to EmberCL.
Remove some unused variables in the kernel created in RendererCL::CreateFinalAccumKernelString().
Use glm namespace for vec classes if GLM_VERSION >= 96, else use glm::detail.
As a result of using glm namespace, all instances of min and max had to be qualified with std::
Split ComputeCamera into that and ComputeQuality().
Reduce the amount of ComputeCamera() and MakeDmap() calls on each incremental iter that doesn't use temporal samples.
Fix clamping bug with DE filter widths.
Provide functions to return the kernels from RendererCL to assist with diagnostics and debugging.
Prevent extra newline in EmberRender when only rendering a single image.
Add the ability to delete an ember at a given index in EmberFile.
Allow deleting/focusing ember in library tab with delete and enter keys.
Reorder some code in Fractorium.h to match the tabs order.
Add and call ClearFinalImages() to clear buffers in controller to fix bug where previous CPU render would be shown for a split second when switching from OpenCL back to CPU.
Refactor ember library pointer syncing to a function SyncPointers().
Add the ability to save ember Xmls to an unique automatically generated name after the first time the user has specified a name.
0.4.0.5 Beta 07/18/2014
--User Changes
Allow for vibrancy values > 1.
Add flatten and unflatten menu items.
Automatically flatten like Apophysis does.
Add plugin and new_linear tags to Xml to be compatible with Apophysis.
--Bug Fixes
Fix blur, blur3d, bubble, cropn, cross, curl, curl3d, epispiral, ho,
julia3d, julia3dz, loonie, mirror_x, mirror_y, mirror_z, rotate_x,
sinusoidal, spherical, spherical3d, stripes.
Unique filename on final render was completely broken.
Two severe OpenCL bugs. Random seeds were biased and fusing was being
reset too often leading to results that differ from the CPU.
Subtle, but sometimes severe bug in the setup of the xaos weights.
Use properly defined epsilon by getting the value from
std::numeric_limits, rather than hard coding 1e-6 or 1e-10.
Omit incorrect usage of epsilon everywhere. It should not be
automatically added to denominators. Rather, it should only be used if
the denominator is zero.
Force final render progress bars to 100 on completion. Sometimes they
didn't seem to make it there.
Make variation name and params comparisons be case insensitive.
--Code Changes
Make ForEach and FindIf wrappers around std::for_each and std::find_if.
