    cursor-renderer-native: Take CRTC transform into account
    
    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.
