[Chris Ball]

Hi,

Here's a tested patch to fix http://docs.openmoko.org/trac/ticket/1244,
please apply.

Thanks from a very happy Freerunner owner,

Subject: [PATCH] Fix x-coord of input when rotated.

It seems that KdComputeMouseMatrix() requires us to call it after setting
up the desired randr, but before we set pScreen->{width,height} to our
new orientation.  This patch does that, with the result that rotating to
left/right no longer introduces a 120px xcoord offset.  Fixes Trac #1244.
