Several features and fixes…

New option to automatically write tile set file when project is saved.

Separated menu entries to load a color palette into load from palette and image file. Load from palette now uses the visual palette browser where palette previews can be seen.

Added new color palettes and link to lospec.com to load palettes from there.

New function to Replace / Swap colors. Can be found in menu Colors > Replace / Swap…
Swap colors function affecting brush only has been moved to menu Brush.

Layer effect "layer mask" added. It allows to make parts of a layer being invisible without altering/removing the actual pixels.
Can also be used to add alpha transparency even when the project uses simple transparency (certain color index is transparent).

Added Shift movement lock to layer move tool.

Fix: Exporting Windows Icon with alpha transparency creates invalid files. Also added an error message when image size exceeds 256 pixels in either width or height, because this is the maximum size for the file type.

Fix: Crop + undo turned frame delay to 1ms.

Fix: Internal error when creating a very large project like 32000x32000 although having enough memory.

Fix: Misalignment with rectangle and circle tool and even sized brushes. In some situations the brush preview was not placed correctly before drawing starts and also it started to draw the circle/rectangle at the wrong position, shifted by one pixel.

Fix: Added "Name:" field to GIMP palette files so that Krita can open it.

Fix: Increased robustness for Gimp palette files by ignoring leading tabs and spaces at color value rows.

Fix: Inaccurate snapping after releasing mouse button with snap grid and line tool. The final line did not draw the same way as the preview. Instead it moved one pixel away.

Fix: When using "Animation/Create 3d Animation", the AnimBrush playback setting was ignored. It always played forward.

Fix: Light table (onion skin) shapes where rendered although the project had only a single frame.

Fix: Several functions in tile palette window could be used though sync mode was disabled but is required. Leading to problems.

Fix: Sometimes an internal error occurred when closing application while having tile palette window open.

Fix: Internal error in brush container. Did not appear in production for unknown reason.

Fix: Project settings option "Store Thumbnail" got lost when saving and loading a project file.

Fix: With some zoom levels < 100% the transparency pattern was shining through opaque pixels.

Fix: Display glitch when zooming or scrolling. Due to some rendering optimizations a glitch can appear that showed parts of the canvas pixels as transparent.

Fix: Memory leak with layer effect renderer for displaying other project.
