-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.
-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.
-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.
--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.
-Edits will not save back to the file in memory on render completion when preview renderer is running.
--Bug fixes
-dc_perlin was crashing on Nvidia when using SP.
-Duplicate images were randomly getting added to the file in memory.
-Crash when opening an Xml with less than 2 flames in it.
--Code changes
-Use raw array of floats in OpenCL for perlin noise, rather than float3/double3.
-Add some default cases to dc_perlin.
-Redo singleton pattern yet again. Deriving from a templated Singleton<T> class was creating a separate instance per module. Now only one instance of each type will ever be created and it will be wrapped in a shared_ptr which guarantees its deletion as main() exits.
-The concept of "saving back to file in memory" has been removed. The current ember is saved back to memory whenever the render completes and the thumbnail will be updated each time.
-Command line programs now default to using double precision.
-The --bits argument has been removed and replaced with --sp to specify single precision. If omitted, DP is used.
-Remove the --seed option, it was never used.
-Remove the --sub_batch_size option, it has been part of the Xml for a long time.
-Remove --hex_palette argument for EmberRender, it only makes sense in EmberAnimate and EmberGenome.
-Set enable_jpg_comments and enable_png_comments to false by default. It was a very bad idea to have them be true because it reveals the flame parameters used to render the image which many artists guard closely.
--Bug fixes
-Continuous update was broken.
-Undo list was broken with new Library tab design.
-Force repaint on xform checkbox change to ensure circles are immediately drawn around selected xforms.
--Code changes
-Remove save to back to file in memory icon, document-hf-insert.png.
-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.
-Really fix locking of affine scale.
--Code changes
-Remove dependency projects from the solution. Move to a project design where they are built once via command line and stored in a /Deps folder.
--Because of this, libpng is built as a static lib instead of a dll because that's what its command line makefile supports.
--Remove libpng16.dll from Wix installer.
-Remove all configs except for debug and release.
-Remove all platforms except for x64.
-Add #define __TBB_NO_IMPLICIT_LINKAGE 1 to prevent tbb from locking for tbb_debug.lib by default on debug builds.
-Put Ember.rc in a filter folder in the project.
-Place pragma warning disable statements in PCH files rather than in projects. This makes it easier when using Qt Creator.
-Move all resource files to the MSVC folder.
-Set all targets in QtCreator project to their lowercase names to be more *nix friendly. Set -l link statements to use these new lowercase names for ember and embercl.
-Rework projects to favor shadow builds.
-Remove the symlinks.sh file and all references to it. It was never needed. Instead, just specify multiple include and link paths in the .pro files.
-Change WIN32 to _WIN32.
-Fix a few code warnings.
-Draw selection circles around all selected xforms plus the current one.
--Bug fixes
-Add control key as a modifier to increase the amount a spinbox is changed when using right mouse drag to edit. Previously only observed shift key to decrease the value.
-Change the copy/paste selected xforms shortcuts to be Ctrl+X+C and Ctrl+X+V.
--Code changes
-Add function Fractorium::IsXformSelected() to determine if an xform has been selected with the checkboxes.
-Split VariationList into .h/cpp files.
--Make VariationList.cpp the only place where the variations files are included from. This speeds up the build, but variations can no longer be directly instantiated.
--Variations are no longer exported.
-Allow locking of the scale at which affine circles are displayed.
-Allow user to toggle whether xform will be animated when generating sequences. Also show the animate value when loading.
--Code changes
-More conversion to C++11 style code.
-Add another value to the eXformUpdate enum called UPDATE_CURRENT_AND_SELECTED in anticipation of future work.
-Remove some old #defines.
-Add a new dialog for editing QSS stylesheets. Allow for saving, reloading and setting styles as default.
--Include a dark style with the installation called dark.qss.
--Also add support for themes such as Fusion.
--Resize some controls to better fit with the new style.
-Add an option to specify the number of random embers generated on startup. 1 is the minimum and the default.
--Bug fixes
-Properly enable/disable thread priority label in final render dialog in response to enable/disable of the OpenCL checkbox.
-Remove all inline stylesheets.
-Show xaos spinners with 6 decimal places.
--Code changes
-Remove redundant comparisons to nullptr, use ! instead;
-Give some controls valid names instead of the auto generated ones.
-DoubleSpinBoxTableItemDelegate.h: Add virtual keyword to overridden functions.
--Adjust xaos cells when any group modification is made, such as random, clear, or row/col change.
--Remove some old style sheet code on the xforms tab that doesn't seem to make sense and was probably just a workaround for a transient Qt bug, of which there are hundreds.
-Nvidia OpenCL compilation was broken for density filtering due to ambiguity in the arguments to min(). Fix it by casting.
-Put Nvidia block size in DE back to 24 where it used to be. Nvidia fails when it's 32.
-Fix misspelling of the word "Rendering" in failure messages in final render dialog.
-Put FillSummary() back when loading an ember.
-Properly disable add final xform button when a final xform is present.
Add the ability to set the current xform by pressing F1 - F32.
Add the ability to toggle an entire row or column of xaos values.
--Bug fixes
Prevent xform index flickering whenever changing the number of xforms.
--Code changes
Remove ForEach() wrappers and replace with range based for loops with auto.
Replace every regular for loop with a range based one where applicable. Note this doesn't work everywhere.
Make event filter application wide.
Add parameter to FillXforms() to specify the index to select, default 0.
Rename some scroll areas and layouts to names that make sense, rather than their designer defaults.
Add the ability to apply operations to a selection of xforms, rather than just the current one.
Update tool tips accordingly.
--Bug fixes
Fix NAN in equalized weight calculation when all weights are set to 0.
--Code changes
Clean up strange nested usage of Update([&]()) calls when changing xform color index via either the spinner or scroll bar. Made no sense.
Make ISAAC RandBit() use RandByte() to be slightly more efficient.
Put FillXforms() in the controller where it belongs, rather than the main window class.
Add UpdateXform() function to the controller to handle applying operations to multiple xforms.
Remove the word "Current" out of most xform related functions because they now operate on whatever is selected.
Properly use Update() for various xform operations whereas before it was manually calling UpdateRender().
Also properly use Update() in places where it was erroneously using UpdateXform() for things that did not involve xforms.
Block signals in FillXaosTable().
Add new file named FractoriumXformsSelect.cpp to handle new xform selection code.
Make xaos display a matrix rather than a single column. This will be moved out into its own tab since it's no longer xform dependent, but that will be in a future commit.
Remove xaos from/to button since it's no longer applicable.
Add test function to Isaac to return just one random byte. Might be used in the future.
--User changes
Use actual strips count when computing memory requirements in the final render dialog.
Output CL_DEVICE_ADDRESS_BITS when passing --openclinfo to command line programs.
Warn if single/total allocations are greater than the max allowed for OpenCL in the final render dialog.
Make about box properly sized for different fonts.

Fix incorrect calculation in dc_cube variation when using OpenCL.
--Code Changes
Major work to get it running on Linux.
Migrate from QGLWidget to QOpenGLWidget.
Delayed init due to QOpenGLWidget.
Break RendererBase::MemoryRequired() into two functions, it and HistMemRequired() and return a tuple.
Add GlobalMemSize() and MaxAllocSize() functions in OpenCLWrapper.
Change CHOOSE_XFORM_GRAIN to be 16384, so we can & with 16383 instead of using modulo when selecting an xform. This results in a 9% speed increase on the CPU.
Save each newly loaded ember in a file called "last.flame" in the executable folder. This will help diagnose crashes that occur when switching embers.
Use nullptr instead of NULL in the Fractorium project. It had previously been done in all other places.
--User Changes
Size is no longer fixed to the window size.
Size scaling is done differently in the final render dialog. This fixes several bugs.
Remove Xml saving size from settings and options dialog, it no longer applies.
Final render can be broken into strips.
Set default save path to the desktop if none is found in the settings file.
Set default output size to 1920x1080 if none is found in the settings file.
--Bug Fixes
Better memory size reporting in final render dialog.
--Code Changes
Migrate to C++11, Qt 5.3.1, and Visual Studio 2013.
Change most instances of unsigned int to size_t, and int to intmax_t.

Color code xforms like Apo does.
Change other aspects of xform color drawing.
Add option to invert the Y axis to both the options final render
dialogs.
Coordinate Y axis setting with preview renders.
Add option to show all xforms when dragging. Previously, only the
current one was shown.
Make final render dialog appear in the middle of the screen.
Immediately draw yellow selection dot on mouse down.
--Bug Fixes
Resize final render dialog vertically if it's taller than the 90% of the
desktop area.
