1) Publish methods for clearing and blackening the bitmap

2) Always do the calculations for a possibly scaled view.
Even if we prevent the user from changing the view size,
the Monitors control panel in the emulator may still try to
select a resolution which is too large for the screen,
and thus the window will have to be reduced to fit,
and thus the screen and bitmap co-ords may not match
