Fixup alpha bitmap generation for Windows.
This improves upon d6f58fd25eeca84a94528409a05b80aa5172b8b8 by using the BitmapEx ctor instead of manual initialisation. Several EMF+ files would otherwise show up horribly mangled on Windows. Change-Id: I1808cb45818f3f0118653164c83c49d6134b9324 (cherry picked from commit fefab3bb38f55471d9fa9316d1249ad00adefc37)
