rdb 3c6b6e47ec glgsg: don't call glLineWidth with higher value than maximum 
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

rdb 8ad0cb6b57 glgsg: add support for p3d_FragData fragment output 
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

rdb 53cec96c07 Fix draw calls being listed under Primitive Setup in PStats, etc. 
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.

rdb c18cdcf36e display: add support for debug markers, to help with debugging 
This is useful when running Panda in a tool like apitrace, so that the different calls in a frame are ordered in a neat hierarchy.
