If only I could find that place again ... I have been reading that
many code snippets out there on the Net ... Sorry for identifying you
with this way of coding - I actually thought it is in cl-opengl but
it doesn't seem to be, obviously. So: Beg pardon.

ha-ha, this is Luis's punishment for stealing the name cl-opengl from me. :) He will be fielding support calls from the legions of Cello users forever. Fortunately, Frank is the only legion.

[Explanation: Luis, I am betting Frank is referring to my pre-CFFI cl-opengl code. Frank, there are two cl-opengl's, mine (deprecated) and Luis's.]

hth, ken
