I notice that, by default, we pretend we have a touchscreen instead of a
mouse (-usbdevice wacom-tablet option) for the qemu bsp's.  Is there
some reason for this?

I have experimented  some and, with other adjustments, have found
it possible to not specify it, but I do admit interaction with the target
graphics window does seem "cleaner" if we do use it.

Avoiding screen grab is the best reason (and all that I need) to use
the tablet options.

Cheers,

Exactly. A mouse only gives relative position data so it has to grab,
the touchscreen can do absolute position and hence doesn't need a grab.

That does seem cleaner.  I do see, also, that if there is a /dev/input/touchscreen0,
host mouse movements, etc, also appear on /dev/input/mice.  Might that be
confusing?  Is there some way for qemu to emulate a touchscreen while suppressing
the mouse?
