The Linux-VR demos stick these magic numbers in
/etc/pointercal, I assume that this file is read
when the touch screen driver is initialised.
I'm also seeing some in-accuracies is position,
getting worse towards the top/right, when using the
R rotated screen - though normal (no rotation) works
well. Anyone else seen this??
