UI cursor illegible in stereoscopic 3D
When using stereoscopic 3D modes like side-by-side, the UI cursor is still drawn by the OS on top of the game window. This makes it difficult to use the UI in such modes without resorting to closing an eye.
Clearly one solution is to have the engine draw the cursor itself, so that it will be projected correctly in stereoscopic 3D.
Fixed|UI|Client: Show projected mouse cursor in all displacing VR modes
All VR modes that move window content around should use the custom cursor
since it will then be appropriately duplicated in the per-eye views.
