- ogl_tex_bind now supports multitexturing (avoids need to get id and then bind manually) - provide nicer API for querying texture properties (no longer one big getter). improved GUI determination of texture alpha. - renderer: another see-if-texture-has-alpha and fixed alpha map code (wasn't checking if all are same size. only worked because the first map was larger than the rest This was SVN commit r2647.
