v0.4.2

Patch release that mainly focuses on fixing some bugs/issues. This release is file compatible, but not network compatible with the previous release.

Changes and Additions:

• Fixed the "Integer Division by Zero" error when loading some files
• The brush tool, eraser tool, and selection tools now change color between white and black depending on how bright the objects behind them are. This should allow the cursor and tools to always be visible
• Clamp brush pressure to stop incompatible drivers from breaking InfiniPaint
• Added limit to image crop bounds
