The new text renderer in graph works w/ everything GL2ES2,
ie. ES2, GL2, GL3, GL3bc, GL4, GL4bc, hence core and fwd - yes.

Even though it works nice,
we will change the API a bit to make it more comfortable.
Another 'warning': We sure miss some of he font metrics provided,
since we are not rendering it with a scanline (bitmapped) methodology.
So some font experts might not be satisfied.

Call for help: Whoever is a font expert and can help with
making the scanline font metrics available in the curved 'bezier' world
is asked to help us out in this regard.
