[PULL 1.14] device scaling, memory leak fixes

[Peter Hutterer]

Two memleaks plugged, the other two patches are changing device scaling.
One fixes the behaviour of absolute devices in relative mode (i.e. a circle
on a tablet will now be a circle on the screen), the other one fixes a
off-by-one pixel error when the transformation matrix is used to map a
device to a screen.

The following changes since commit 6abc41689cfd274f5aa8bdfbfcd4e3dd7d0249fa:
