Make conversion of semi-transparency to opaque formats consistent
Currently the non-standard opaque formats all perform inverse premultiply
on semi transparent pixels when saving. This is only performed on RGB16
and RGB32 when explicitly converting to the formats, but not when drawing.
This patch changes the conversion to be consistent across the board so
less common formats are treated the same as the most common ones. This
also makes drawing and converting to the these formats much faster.
