Noel Grandin e435c0749b drop OutputDevice::GetBitmapEx in favour of returning Bitmap
as part of the project of removing BitmapEx in favour of Bitmap, now that we can store RGBA data in Bitmap.

This mostly just moves the Bitmap->BitmapEx from inside OutputDevice to the various call sites,
from where I can make further improvements.
