[PATCH xf86-input-mouse] Make absolute input reporting in Solaris aware of resolution changes

[Michael Thayer]

Currently on Solaris absolute input reporting only takes resolution changes
into account when the video driver is using the pre-RandR 1.2 APIs, and
there it uses the physical resolution, not the virtual.  This patch fixes
those two things.

This builds against master but actual testing was done against 1.7.2.  I think
that the two are close enough for this to be safe though.
