Psychtoolbox>Screen.{mex*} subfunction

Screen(‘EndOpenGL’, windowPtr);

Finish OpenGL rendering by external OpenGL code, prepare 2D drawing into window
‘windowPtr’.
This is the counterpart to Screen(‘BeginOpenGL’). Whenever you used
Screen(‘BeginOpenGL’) to enable external OpenGL drawing from Matlab, you *must*
call Screen(‘EndOpenGL’) when you’re finished with a window, either because you
want to draw into a different window, or you want to use a Screen command.
Psychtoolbox will abort your script if you omit this command.
