comparison src/video/quartz/SDL_QuartzVideo.m @ 1662:782fd950bd46 SDL-1.3

Revamp of the video system in progress - adding support for multiple displays, multiple windows, and a full video mode selection API. WARNING: None of the video drivers have been updated for the new API yet! The API is still under design and very fluid. The code is now run through a consistent indent format: indent -i4 -nut -nsc -br -ce The headers are being converted to automatically generate doxygen documentation.

 Since there is a bug in Apple's screen switching code
 that does not update this variable when switching
 to fullscreen, we'll set it manually (but only for the
 main screen).

 In order to determine if a direct copy to the screen is possible,
 we must figure out if there are any windows covering ours (including shadows).
 This can be done by querying the window server about the on screen
 windows for their screen rectangle and window level.
 The procedure used below is puts accuracy before speed; however, it aims to call
 the window server the fewest number of times possible to keep things reasonable.
 In my testing on a 300mhz G3, this routine typically takes < 2 ms. -DW
 Notes:
 -Calls into the Window Server involve IPC which is slow.
 -Getting a rectangle seems slower than getting the window level
 -The window list we get back is in sorted order, top to bottom
 -On average, I suspect, most windows above ours are dock icon windows (hence optimization)
 -Some windows above ours are always there, and cannot move or obscure us (menu bar)
 Bugs:
 -no way (yet) to deactivate direct drawing when a window is dragged,
 or suddenly obscured, so drawing continues and can produce garbage
 We need some kind of locking mechanism on window movement to prevent this
 -deactivated normal windows use activated normal
 window shadows (slight inaccuraccy)
