I somehow managed to read this as a 2D patch. 100% agreement for the kernel. -- Eric Anholt e...@anholt.net eric.anh...@intel.com signature.asc Description: This is a digitally signed message part -- Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!

The scanout hardware can handle up to this size, so there's no reason to
restrict it to 2048x2048.

The only thing I'm concerned about is proper handling of 3D drawing to
that big. What happens?
