another thought on a different approach, assuming that in GL one can't
define textures before the initialization done by the vo.

after the gl vo has finished the initialization, an optional external
program (eg. -vo gl:extnprog=myprogram) is called from within mplayer
to further define/modify the vo created texture and then exit.

this is all assuming that the spherical modification of the texture
can't simply be done in some gl-script (if such a thing exists) file
which the vo can be passed in a parameter and get loaded into the GL,
making any need to execute another program unnecessary.  for all I
know the gl vo may already have some function to do this.
