At this point I am considering only OpenGL ES2.0 support, mainly because
I don't have time for both ES2.0 and VG, and ES2.0 support in drivers
for embedded systems seems to be better compared to OpenVG support.

There is glMapBufferOES for GLES2 (which seems to be quite standard), so
we can easily solve this with runtime extension detection and support a
fallback to just use a normal glBufferData() code path otherwise.
