FULLSCREEN and DOUBLEBUF


Excellent. Now I know what to do in this instance and I understand the 
principle.

I hesitantly tried this:

 ??? screen = pygame.display.set_mode((720,480), pygame.FULLSCREEN | 
pygame.DOUBLEBUF)

Hesitantly because I expected the *bitwise or operator* (|) to work like 
a toggle, so FULLSCREEN or DOUBLEBUF.

No errors were reported, but how would I check that DOUBLEBUF had been 
set? Is there a general rule, such as replace 'set_something' with 
'get_something'?
