MacDue 60356c8dde LibGfx: Support getting a bitmap for a region of painter ...

This will be needed so we can apply filter effects to the backdrop
of an element in LibWeb.

This now also allows getting a crop of a bitmap in a different format
than the source bitmap. This is for if the painter's bitmap does not
have an alpha channel, but you want to ensure the cropped bitmap does.
