annotate docs/man3/SDL_UpdateRects.3 @ 1625:7e89aa7843c5

Fixed bug #193 The attached patch is mostly cosmetic: Currently, we always add both -framework OpenGL and -framework AGL for Mac OS X command line builds. However, the former is only used for the Cocoa video driver, and the latter only for the Carbon video driver (as far as I can tell, at least). Hence the attached patch modifies configure.in so that each only gets added to the list of frameworks if the corresponding video driver is enabled.

18 It is adviced to call this function only once per frame, since each call has some processing overhead\&. This is no restriction since you can pass any number of rectangles each time\&.

20 The rectangles are not automatically merged or checked for overlap\&. In general, the programmer can use his knowledge about his particular rectangles to merge them in an efficient way, to avoid overdraw\&.
