- Ben Omari sent an update version of his DirectX8.py, Jean-Michel Soler updated his disp_paint.py and Campbell Barton contributed a new one: sel_same.py (for now it's in the UV menu). Thanks all, great scripts; - small updates in some other scripts. BPython: - Finished wrapping radiosity functions for the Radio submodule; - doc updates.
