Panda was adding a column with weights (0, 0, 0, 0), but these weights don't add up to 1 so no useful identity matrix can be produced. Instead it's better to fall back to the OpenGL default, (0, 0, 0, 1).
I'm also defaulting the transform_index values to (0, 1, 2, 3) to support non-indexed skinning (although that's pretty esoteric, given that that only supports 4 transforms...)
Officially, in core profile OpenGL 3.2+, calling it with a value higher than 1.0 is an error, but many vendors seem to let us. Apple's implementation does not. It appears that checking the maximum line width is a way to deal with this.
Fixes#466
This is necessary for GLSL 1.30 which deprecates gl_FragData but does not yet support layout(location=) specifiers
Also fix some function pointer checks for pre-GL 3.0
Fixes#455
Previously, all draw calls would be grouped under "Primitive Setup", rather than under the appropriate bin collector. This commit fixes that and adds a few other useful collectors as well.
