we never actually erase device in SetOutputSizePixelScaleOffsetAndLOKBuffer

Browse Source 
So simplify the code.

The reason this currently "works" is that we always set the
background to COL_TRANSPARENT, and when we do that,
the DrawRect() logic will short-circuit and do nothing.

Which also means we can inline ImplSetOutputSizePixel
into SetOutputSizePixel, since it has only one call site.
