Mainly a couple of fixes, but also an important feature: group/ungroup layers
Changes
Shape of cursor for freehand drawing made to be more slim again.
Improved button visualizations in color palette window.
Added layer group and ungroup functions.
Using ESC key in the web color edit field in the color palette editor window now removes focus from the edit field.
Fix: If there was no other group/layer after a group then the layers of that (last) group could not be moved out of it by dragging to the very bottom.
Fix: When changing the delay of a frame directly in the corresponding input and using frame playback/control buttons, the delay was not correctly stored
Fix: When adding a layer and doing undo in a fast way while starting to apply tooling like fill on that canvas, an internal error occurred.
Fix: Shortcuts that are used for different working areas (tabs) in the color palette window where considered to be conflicting and the user had to choose one of the operations.
Fix: When having pixel perfect drawing enabled and the license key was removed then the application did not start correctly.
Fix: When using middle mouse pan and mouse wheel very quickly the same time then sometimes lines where drawn.
Fix: Freeform brush grab not working correctly if stencil is enabled.
Fix: ESC with freeform line tool was not working correctly.
Fix: Merging a layer group sometimes raised an internal error.
Fix: Extended edit mode with filled shapes did not work with interactive gradient fills.
Fix: Active tool did not cancel automatically when loading image/animation/project files leading to problems
