If binding a NULL program, disable any vertex arrays we previously enabled. This is done in case the caller is switching to the fixed function pipeline and needs more control over the vertex arrays. So to minimize state changes, don't bind a NULL program between draws if you're just going to bind a new program later.
Ignore whitespace changes - Everywhere: Within whitespace: At end of lines:
