inline qgl2 funcs by references/no err checking
inline qgl2 funcs by references/no err checking

we successfully inline functions by reference, but
we don't do any error checking: we don't check that
the actual parameters match the declaration, and we
don't backfill the qgl_scope so that CheckSymtab will
validate the call.

The latter should be unnecessary because the runtime
checking should replace the static checking, but right
now it's something to watch for
