[Bug 14375] Mouse cursor flickers in Myst IV - Revelation

The actual cursor flicker happens because the entire scene renders twice every
draw. The cursor is not done through the cursor API, but is a 3D object. So
what happens:
-Begin draw-
The scene gets rendered
The cursor gets rendered
The scene gets rendered again
-End draw-

According to the comment in transform_world@wined3d/state.c this behaviour is
known and sort of wanted. The attached patch checks for this special case.
