6d8e1abfc0 Improve input sensitivity
We now use doubles until the last minute, which makes it so we can move
the pointer more precisely. This also includes a fix for tablet tools,
which move absolutely and sometimes do not update the X or Y axis.

c8f97a3a2c Use surface matrix for software cursors
A similar change should probably be applied to hardware cursors, though
more complicated. Also, this doesn't actually fix the issue where the
cursor is too small when over a scale=2 surface. Apparently they don't
set their cursor scales to 2. Seems like a client bug? idk
