finally found time to look at it and the result is not good.
The idea of the patch was to get the horiz/vert movement of abs devices that
are in relative mode to follow the physical movement. so a circle on the
device should be a circle on the screen, not an ellipsis.

that works, as long as the device is truthful about it's resolutions.
synaptics touchpads aren't. my touchpad here has an announced ranges of 4000
and 3000 units (x and y, respectively) and a resolution of 75 and 129. i.e.
my touchpad's effective area is supposed to be ~54mm wide and ~24mm high.
and that's not even close to the real dimensions.

so with this patch, the movement is stunted, which gives the result you've
been seeing.

I don't know how to fix this yet, seems like we can either have touchpads
not work correctly or tablets not work correctly (withough resorting to
gross hacks).

Cheers,
   Peter
