- Shadow status update thresholds on Savage4 were reversed. Fixed now.
- Fixed cobIndex on Savage2K. It used only a 4K COB so far. Now we have
full 128K.
- Program the shadow status thresholds correctly on Savage2K.
- Savage2K reports used entries in the queue in qword units instead of
dwords. Fixed WaitQueue2K accordingly.
- Event counter 0 is in status word 2 instead of status word 1 on Savage2K.
Fixed ShadowWait accordingly.
- Added a ShadowWaitQueue function that doesn't idle the engine all the
time. This improves 3D animation smoothness with concurrent
2D activity when shadow status is enabled.
