Subject: Implement material maps for exporting objects with multiple materials
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=bde3ec824d300e9aff11914406fb76dd9016e387;hp=bde3ec824d300e9aff11914406fb76dd9016e387;p=libs%2Fgl.git

Implement material maps for exporting objects with multiple materials

This replaces the material texture feature which was removed earlier.  The
principle is similar (store material color values in a texture) but the
maps are global, making it possible for multiple objects to use the same
map.
