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.

/* Limits for the overlay/textured video source sizes. The documented hardware
* limits are 2048x2048 or better for overlay and both of our textured video
* implementations. However, we run into the bigrequests limit of (currently)
* 4MB, which even the planar format's 2048*2048*1.5 bytes is larger than.
* Conveniently, the HD resolution, even in packed format, takes
* (1920*1088*2) bytes, which is just shy of 4MB. Additionally, on the 830
* and 845, larger sizes resulted in the card hanging, so we keep the limits
* lower there.

* While the HD resolution is actually 1920x1080, we increase our advertised
* size to 1088 because some software wants to send an image aligned to
* 16-pixel boundaries.
