As PixelsMovement class uses the extra cel to show the pixels that we're moving, we cannot show brush previews of quicktools (as the brush preview uses/destroy/regenerate the same extra cel for its own purpose).
Aseprite Source Code
If you are here is because you want to learn about Aseprite source
code. We'll try to write in these README.md files a summary of each
module/library.
Modules & Libraries
Aseprite is separated in the following layers/modules:
Level 0: Completely independent modules
These libraries are easy to be used and embedded in other software because they don't depend on any other component.
- allegro: Modified version of Allegro library, used for keyboard/mouse input, and drawing 2D graphics on screen.
