yeah, fine with me, just double-check it for cursor jumps please. I saw a few
of them while testing with this patch and though I don't see why this patch
would've triggered them make sure anyway. Usage was as illustrated above, but I
don't know the exact sequence triggering jumps, they were sporadic (but
frequent enough).

I think combined movement should work well enough, though it needs testing
whether finger movement on the 'holding finger' would interfere with actual
movement. There's likely some more complex solution to switch the pointer
finger once a movement threshold is met but let's see if the simple solution is
enough (synaptics would indicate it is)
