v0.0.1

AI disclosure: The code in this mod was written with an AI assistant (Claude, by Anthropic), directed and tested by the mod's author. The Powder Toy and Box2D themselves are not AI-written.

First release of Rigid Body Mod for The Powder Toy: solids that move as one piece. They fall, tip over, slide, stack and roll, and float or sink in liquids by density. Seven materials in the Solids menu: RIGD (iron), RWOD (wood), RRBR (rubber), RICE (ice), RSTN (stone), RFOM (foam) and RGLD (gold). See the README for details and known limitations.

Newer version available: v0.0.2 fixes water leaking out of hollow bodies and adds air forces and the PUSH tool.
