Log:
[Win32k]
- Implement the set of DeferWindowPos functions. Regedit (one of many application) uses it
and allocated three when it should be four. This was a good test to verify the batch list
growing routine. Instead of drawing per DeferWindowPos call, now a real list is created
and run down as a batch.
- ReactOS should handle this the correct way and a good test case is located here:
http://bugs.winehq.org/show_bug.cgi?id=23187
- The code is from wine and modified for the use in ReactOS.
