* In theory, gl*GetProcAddress can return different function pointers at different times, but in practice this does not happen. Also we have many more problems if there was an implementation that did this. * In reality what can happen if we don't preserve existing function pointers is that any call to gl*GetProcAddress will overwrite required emulated functions for e.g. EXT_dsa if the implementation doesn't support the extension but does return valid pointers for the query.
