wayland/dnd-surface: Scale DnD-surface-actor content if necessary

Browse Source 
Since the recent clutter-content work, legacy scaling (in contrast
to the new stage-view-scaling) only applies to surfaces that belong
to a window. This broke scaling of DnD surfaces.

As a workaround, apply the same scaling on DnD-surface-actors until
we use stage-view-scaling by default and can remove this again.

Also: small corrections of geometry calculation
