This is not a feature request, but pix_buffer2tex could be an
interesting object.. On those cards with 256MB of texture memory...

Johannes, could you please put FTGL in GemLibs? or add me as a developer
so that I can do it?

pd-extended should have FTGL and not be stuck with gltt, or no text support.

Thanks.
