Eric Anholt 0e3f1252da glamor: Avoid using GL_QUADS on VC4. 
Improves text rendering from about 284k glyphs per second to 320k
glyphs per second.  There's no GL extension for probing this, because
of the philosophy of "Don't expose whether things are really in
hardware or not."

* loop from the left-top box to the right-bottom box,
