Then I would
be drawing rectangles which are not ready for a redraw yet. Does
UnLock release only last lock or all locks on these old DX versions?
Well, you need to store the rectangle at Lock time but only draw it at
Unlock time. And I have no idea if any game ever does concurrent locks (so I
have no idea how concurrent lock work).
If you want to see concurrent locks, grab Command & Conquer Tiberian
Sun. It doesn't use those old APIs you're talking about, but if you
wanted to know...
