--Code changes
-Cleanup some casting in depth_blur, depth_blur2.
-Fix xform selection logic to prevent selecting hidden pre and post xforms.
-Remove the "Current" visibility option for pre/post affines. Instead just have "Selected" and "All". If none are selected, show current.
-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.

-Add gnarly variation.
--Bug fixes
-Fix reading of post variations in .chaos files.
-Make selection of points on color curves control apply only to the current selection as specified by the radio buttons below.
--Code changes
-Use std::complex<T> type in some variations' CPU code.
-Dragging library items to a new position was not properly resetting the current flame pointer, so subsequent edits would unintentionally overwrite different flames.
-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.
-Clear all color curves when clicking Reset while holding down Ctrl.
-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.
--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.
-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 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.
-New look for the About dialog, it was growing too large before. More work to be done on it in a follow up commit.
--Bug fixes
-Fix build with new glm, no longer uses type_int.hpp.
-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.
-Attempt to preserve xaos when adding xforms. Note this is not an exact copy, but just a preservation of some values based on position.
-Add some acceleration to the changing of spinner values when dragging the right mouse button to adjust.
-Make the pivot be the center of the viewable area when doing drag/rotate/scale with the right mouse button.
--Clamp minimum scale to 10
--Draw a line from the mouse position to the pivot.
-Keep a cache of the last added final xform with each flame so that it can be quickly added, removed, then added back for testing its effect.
--This is not saved with the xml file and is solely for interactive editing.
--Bug fixes
-File filtering in open and save dialogs were broken.
-Right clicking on integer spin boxes was causing the context menu to pop up, when it should be supressed just like double spin boxes.
-Deleting xforms was still broken.
--Code changes
-Refactor the code for adding and pasting xforms into a single global static function called AddXformsWithXaos().
-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.
-Double clicking on width or height spinner resizes both, but scales to the one double clicked.
--Bug fixes
-Show grid setting was not being preserved during program run, only on close.
-Zooming with the mouse wheel was broken for images whose size is greater than the screen area.
-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().
