Yeah, AlphaBlending is not supported (hence the diagonals look jagged)
-- theming is also affected.

NOTE: I have seen this happen on other Windows apps running on
Windows. You need to have the image support an alpha channel - which
I'm not sure icons do. I'm not sure of the API calls that are
required, though, so it may require some changes to the static control
support to render the bitmaps using alpha (in addition to keyed)
