Kevin Lubick 3902628e35 Support WebGL 1.0 with caps 
There is some logic in here for 2.0 as well, just as a
"as long as I was looking at the specs", but only 1.0
is really supported.

This seems to resolve the bug where some GPUs weren't
advertising correctly that they had vertex array object
support, by checking for both extension names (with and
without "GL_" prefix)

Of note, this saves about 18 Kb (5.5 Kb gzipped) of code size
by compiling out the unneeded GLES checks/functionality.
