Ok, this is what I figured out:

Under these conditions:
Full screen game
No virtual desktop
DXGrab = Y
UseXRandR = Y
UseXVidMode = Y
1024x768 res, 1280x1024 virtual res

The mouse cursor stays in window.  XRandR seems preferred over
XVidMode for managing res.

Under these conditions:
Full screen game
No virtual desktop
DXGrab = Y
UseXRandR = N
UseXVidMode = Y
1024x768 res, 1280x1024 virtual res

The mouse cursor doesn't stay in the window.  XVidMode is used in this case.

I hope these are acceptible results. These are with my patch applied
of course. I didn't try without DXGrab.  I dunno if it's deprecated or
not.
