-Small changes to opencl.hpp.
-Center progress bars on Linux.
-Proper sizing of vertical header on the xaos visualization table on Linux.
-Add new preset dimensions to the right click menu of the width and height fields in the editor.

--Bug fixes
-Incremental rendering times in the editor were wrong.
--Code changes
-Migrate to Qt6. There is probably more work to be done here.
-Migrate to VS2022.
-Migrate to Wix 4 installer.
-Change installer to install to program files for all users.
-Fix many VS2022 code analysis warnings.
-No longer use byte typedef, because std::byte is now a type. Revert all back to unsigned char.
-Upgrade OpenCL headers to version 3.0 and keep locally now rather than trying to look for system files.
-No longer link to Nvidia or AMD specific OpenCL libraries. Use the generic installer located at OCL_ROOT too.
-Add the ability to change OpenCL grid dimensions. This was attempted for investigating possible performance improvments, but made no difference.
This has not been verified on Linux or Mac yet.
--User changes
-Allow users to set the Exp value when using the Exp temporal filter type.
-Set the default temporal filter type to be Box, which does not alter the palette values at all during animation. This is done to avoid confusion when using Gaussian or Exp which can produce darkened images.
--Bug fixes
-Sending a sequence to the final render dialog when the keyframes had non zero rotate and center Y values would produce off center animations when rendered.
-Temporal filters were being unnecessarily recreated many times when rendering or generating sequences.
-Exp filter was always treated like a Box filter.
--Code changes
-Add a new member function SaveCurrentAsXml(QString filename = "") to the controllers which is only used for testing.
-Modernize some C++ code.
-Fix improper usage of rand() in cpow2, cpow3, hypertile1, hypertile3D1, hypertile3D2, juliac, juliaq.

-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.

-Add the ability to re-order variations by dragging them in the Info tab.
-Fix crash on palette editor when opening it with certain palette files in a particular order.
-An xform with only a post variation in it might have showed up wrong.

-Make variation state preservation be a little bit more correct in OpenCL.
--Code changes
-Make all iterators on the CPU use a temporary point.
-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.
-Add new Blur Cuve field which controls how blurring increases when moving from the center out.
--Bug fixes
-Undo Y axis flipping from previous commit, it never worked and is not worth the effort.
--Code changes
-The new field is a member of Ember and is called m_BlurCurve, and the corresponding xml field is called "blur_curve".
-Fix OpenCL compilation bugs in a few variations.
--Code changes
-Pre/post variations are now checked for precalcs when creating the OpenCL kernel code.
-Change some enumeration t
-Fix variations: blob2 (broken on CPU), epispiral, hole.
-Fix reading variations from Apophysis: supershape.
-Bump render was broken.
--Code changes
-Flip precalc sina/cosa and apply everywhere by flipping the usage. Flam3 had these reversed and it made the code confusing to read.
-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.
-Fix xform selection logic to prevent selecting hidden pre and post xforms.
-Add hex_modulus.
--Bug fixes
-starblur was wrong.
--Code changes
-Optimize Truchet_hex_crop, Truchet_hex_fill.
-Cleanup Truchet_inv.
-Add new file Variations08.h, and move Gnarly and inkdrop there.
-cosh, coth, csch, sech, sinh, tanh: Scale inputs by PI/4. This will produce different results, but is technically more correct.
--Code changes
-cos, csch: move position of sign flip, shouldn't change output.
-cot, coth, csc, csch, sec, sech, tan, tanh: add optimization.
-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.

-Interpolate color curves when generating a sequence.
--Bug fixes
-Undo a change made last year which gave the wrong color index for final xforms when generating a sequence.
--Code changes
-No longer assume palettes are 256 elements. Can now read longer palettes.
-Ensure OpenCL images always get written when created.
-Clear all color curves when clicking Reset while holding down Ctrl.
--Code changes
-No longer assume palettes are 256 elements. Can now read and write longer palettes.
-Ensure OpenCL images always get written when created.
-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.

--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.
-Disable Start button in final render dialog when Pause is clicked.
--Bug fixes
-Rapidly changing spinner values was causing the OpenCL renderer to report a failure, when it was really just aborting.
--Code changes
-Renderers never internally set abort to true due to a failure. Abort is only set to true by the calling code.
-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.
-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.
-No longer constrain pitch, yaw or depth spinners to -180 - 180.
--Bug fixes
-Properly set color index on padded xforms.
-Adding a padding final xform included a linear variation with a weight of zero to not appear empty. Made it have a weight of 1.
-Always write animate tag on final xform when saving to Xml.
-Motion was being applied to the wrong flame in SheepTools::Edge(), so apply it to the correct one.
-Prevent divide by zero when normalizing variation weights.
-Was accidentally adding the placeholder value of -9999 for motion_offset to varation weights and parameters when applying motion. Set to zero if no value present.
-Clamp flame rotation values to -180 - 180 when reading a flame from Xml.
-Events were not properly wired for user changes in the random rotations per blend controls in the sequencer.
-Fix major UI bugs with sequencer min/max random controls which made it nearly impossible to hand type values.
-Values from rotations per blend and rotations per blend max were not being saved to file between program runs.
-Checking animate for an xform was not applied to all flames even if Apply All was checked.
-Changing interpolation type, temporal filter width, temporal type, and affine interpolation type were not actually saving to the flame when changed.
-Grid on the main window was not being drawn at the right scale initially due to some OpenGL initialization occurring in the wrong order.
-Severe bugs in sequence generation code:
--Improperly detected padding xforms.
--When looking for specific variations during xform aligning, only presence was detected, when it should have been presence plus a weight greater than zero.
--When adding specific variations during xform aligning, must first remove any variations of that type.
--Two variables were unsigned when they should have been signed. This prevented large blocks of code from ever executing.
--When interpolating affines, an EPS that was too small was used, causing affine values to interpolate incorrectly. Instead use 1e-10 to ensure results equal to flam3.
--Code changes
-Modify FractoriumEmberController::UpdateXform() to pass the selected xform index as well as the absolute index to func().
-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.
-Convert OpenGL drawing code to use GLSL. Leave #define in until testing on multiple platforms is done.
-Always use double precision extension defines in OpenCL programs, even if DP is not selected. This is because elliptic now always uses DP.
-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.
--Bug fixes
-Strips renders crashed.
-Better handling of large memory allocations by forcing a free of previous allocations.
-Final render dialog did not properly save last used extension setting.
-Density filtering progress bar in final render dialog did not update if only log scaling was being used.
