Raise XV limit to 2048x2048 to match hardware limits.
The bigrequests limit isn't present in current X servers (tested using
textured video on a 965 with both image and window at 2048x2048 on a
1920x1200 display, and image at 2048x2048, window at 1024x1024).
Remove the artificial limit, enabling full-screen HD video when
rotated.
