Decker 1.37 is a maintenance release with several important bugfixes and enhancements to drawing tools.

Fixes (Web and Native)

• Contraptions no longer bubble internal events to their parent card. (A regression introduced in 1.36)
• Corrected problems with pretty-printing floating-point numbers very close to whole integers.
• The Cursor Info overlay while positioning and sizing objects is now consistent with box selection.

New Features

• The Style menu offers a new option, "Underpaint". When Underpainting is active, drawing tools will not modify pixels containing pattern 1, solid black. This feature makes it easier to quickly add color or patterns to lineart or dithered images. Pressing "u" while using drawing tools will immediately toggle underpainting.

If you find yourself wanting to paint large regions, don't forget that you can always construct a custom brush on the fly:
