WRITEONLY/READONLY.
Added those flags to the internal Lock() calls.
Only copy the surface from screen to surface if not writeonly.
Restrict blitting between display window and surface to the
locked/unlocked rectangle and the clipwindow section.
Added defines for DDHAL_UNLOCKDATA/DDHAL_LOCKDATA, added calls to HAL
implementation.
Ensured that the primary window is created before the constructor returns.
Flag the primary window as transparent so mouse clicks pass through it.
Put the primary window handle into a reserved field for x11drv HAL use.
Major DirectDraw restructure/reimplementation, using an improved component
object model hierarchy. The implementation currently supports:
- DirectDraw over GDI/USER in a window (using DIBsections and
asynchronous updates)
- XVidMode
- XF86DGA2
- All DirectDraw interfaces from versions 1 to 7 (at least in theory)
- Hooks for Direct3D interfaces
