cursor-renderer-native: Take CRTC transform into account

Browse source 
The CRTC level transform (not necessarily the hw transform) must be
taken into account when calculating the position of the CRTC in the
stage coordinate space, when placing the hw cursor, otherwise we'll
place the cursor as if the monitor was not rotated.

This wasn't a problem in the past, as with rotation, we always used the
OpenGL cursor, so the issue newer showed.
