  The exemple code seems quite tedious unfortunately, since all used
symbols must be requested by hand (and must therefore be declared in a
different way, using pointers to functions rather than normal
functions).

  I'm curious: what are the differences between vanillia and ES GL ?
Are they binary-incompatible for the symbols they share ? From other
messages in this thread, they seem to be source-compatible at least to
some level.

  Cheers,
