No, panning still works fine with this change. These dimensions are just
used for clamping the extents of damage after it was transformed into
the CRTC coordinate space. When panning, drmmode_set_mode_major damages
the whole virtual screen, which in this code results in the transformed
and clamped extents still covering the whole CRTC, so the scanout pixmap
gets updated with the contents of the CRTC viewport at the new position.
