-Add Ctrl+g shortcut for generating a sequence.
--Bug fixes
-Fix indendation for variations because of type icon.
-Fix bug when duplicating flame where the new flame wasn't being properly selected.
-Fix bug where clearing a flame was changing size and quality when it shouldn't have.
-Fix bug where reading an Xml palette was failing on linux.
--Code changes
-No longer pad string with null terminator in ReadFile() because std::string already does it.
-Users can now specify animation params on a per flame basis.
--These get saved with the flame file.
-Allow for rotating xforms around the world origin during animation.
-Make the Clear Flame menu item be more comprehensive in how it clears a flame out.
--Bug fixes
-Fix an extremely rare possible memory leak when using motion during animation, which is never used in Fractorium.
-Do not skip to the current flame index, or attach a prefix in the Final Render Dialog when rendering an animation sequence.
--Code changes
-Place all animation params in Ember.
-Remove the Type field from the variations tree and instead just put the type indicator icon next to the variation name.
-Double clicking to toggle variation parameter spinners now resets the value to the default if there is one, else it uses zero. If it is already using the default, it is toggled to 0.
-Add a new button to toggle xaos on and off.
-When duplicating a flame, insert it immediately after the one being duplicated instead of at the end of the file.
-When switching between flames in a file, keep the same xform index selected rather than resetting it to the first xform each time.
-Create a threaded writer for the final render and EmberAnimate so the rendering process does not get delayed by file saving which may take a long time.
-Remove warning which said "Frames per rot cannot be greater than one while Rotations is zero" when generating a sequence.
-Add the Circle_Rand variation from Chaotica.
-Add tool tips to clarify the following items:
--Auto Unique Filenames checkbox in the options dialog.
--Xaos table headers.
--Bug fixes
-Generating sequences using the following variations would be done incorrectly: circletrans1, collideoscope, crob, curlsp, glynnsim1, glynnsim2, hypercrop, julian, julian, mobiusn, nblur, waves2, wavesn.
-Adding/removing nodes from the color curve had accidentally been disabled.
-The applied xaos weight table was not showing normalized weight values.
-Changing the size of a flame was not observing the Apply To All checkbox.
-Do not clamp the Rotate field to +/-180, because this causes the rotation to switch from CW to CCW during sequence generation. Instead, leave it exactly as the user entered it so the rotations proceed in the same direction.
-Fix stylesheets.
-Make various fields in the options window be resettable via double click.
-Get stylesheets working properly on Windows and Linux with Qt6.
-Set default style to Fusion.
--Code changes
-Get build and deployment scripts working with latest versions of Qt6, AppImage, and various library dependencies.
-Add two new macros so it would build with the latest gcc: SINGLETON_DERIVED_DECL_T and SINGLETON_DERIVED_IMPL_T.
-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.
-Change QSS stylesheets to properly handle tabs.
-Make tabs rectangular by default. For some reason, they had always been triangular.
--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.
-Allow for specifying linear or smooth interpolation when generating a sequence in the Library tab (was formerly hardcoded to smooth). This has the effect of exposing the --unsmoother option used in EmberGenome in the GUI.
-Clarify tool tips of the sequence interpolation fields in the animation group on the Flame tab.
-Change caption of the Bounds tab to be Bounds & Log.
-Add support for Chaotica files which specify xform weight as "Base weight" instead of "base_weight".
-Fix bug where Fractorium would crash when a new file was dragged in while previews were still rendering.
--This was done by changing the TreeItemChanged() events in the library tab use a direct connection rather than a queued connection.
--This obviated the need for QCoreApplication::processEvents() calls in the library tree code.
-Fix bug where renaming a flame within a file, then tabbing away did not commit the name change.
--Code changes
-Clean up some warnings about const variables in the latest version of Visual Studio 2019.
-Upgrade installer to latest update of Visual Studio 2019.
-Allow dragging in folders which will be recursively traversed for flame files.
-Allow for adjusting scale via keyboard with the < and > keys.
-Show the count of opened flames on the header of the library tree.
--Bug fixes
-Attempt to preserve xaos when pasting xforms.
--Code changes
-Default flam3 compatibility mode to true.
-Add new keyboard shortcuts:
--P/Shift+P toggles visibility of pre/post xforms.
--L/Shift+L toggles visibility of all/selected pre/post xforms.
--Bug fixes
-Xforms were erroneously able to edit via key pressed when not shown.
-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".
-Duplicate xform will now only add the new xforms with xaos preserved if xaos is already being used in the flame. Otherwise, they'll just be added normally.
-This is a hybrid of the original behavior and the new behavior added a year or so ago.
-Add new style sheet called uranium that is reminiscent of the old Winamp color scheme of the same name.
-All for keyboard presses to edit affines.
--Q: rotate counter clockwise.
--E: rotate clockwise.
--W: move up.
--S: move down.
--A: move left.
--D: move right.
--G: shrink.
--H: grow.
--Hold shift to decrease amount, control to increase amount.
-Change some menu shortcuts to accommodate these new affine editing shortcuts.
-Random xaos now just provides values of either 0 or 1. Hold control to get the old behavior.
--Bug fixes
-Waffle variation was broken in OpenCL.
-Returning to main window after closing the final render dialog wouldn't restart the renderer.
--Code changes
-Recreate the final render dialog each time it's shown.
-Fix some potential OpenCL compilation bugs on circlecrop, circlecrop2, oscilloscope2, Truchet_hex_crop.
-Prevent the minus key from changing the current xform when being pressed in a textbox.
--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.
-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.
--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.
-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.
-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.
-Allow 7 decimal places in variations spinners.
-Try to prevent infinite loop that sometimes happens when drawing grid. Unsure if this actually works since it's very hard to reproduce.
-Update /debian/changelog to use a newer version of ubuntu named artful. Users will need to add that PPA to get it via apt.
-Update copyright year to 2018.
-Allow group dragging and floating of dock widgets.
--Note this has a bug where if tabls are grouped while floating, the tab position is placed on the bottom. It restores to the top when dropping on a dock location. I've filed a bug at qt.io
-Make some tables auto size to their contents because some text appeared obscured on Linux.
-The size of the xforms and palette tabs were preventing the main window from being resized to a small size on lower resolution monitors when docked. So rework scroll areas, minimum sizes and layouts to allow for a smaller main window.
-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.
--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.
--User changes
-Add support for adjusting xform color indices in the palette editor. Fixed palettes can now be displayed there, but they will have no color arrows as they are not editable.
-Add support for independent dimension scaling in the EmberRender and EmberAnimate programs to bring them in line with the final render dialog Fractorium.
--Bug fixes
-File paths with a space in them did not work in the command line programs.
-Any Xml file in the search paths would erroneously be treated as a palette file.
--Code changes
-Change some for loops to while loops when iterating through xforms.
-Allow FractoriumEmberController<T>::UpdateXform() to be able to apply the action to an xform at a specific index.
-Remove old code blocks build files that were never used.
-Make GetPath() return empty string if no path is present in the passed in file path.
-GetTotalXform() was always counting the final xform, even if it was unused.
