I did so in my working copy. I also removed the

from DrawThemeBackground(), ie I AlphaBlend() directly to the screen. I
also made a small test case; the alpha is already missing from the
bitmap returned from LoadImage() - the blitting there already clobbers
the alpha channel for me.
The problem I think is when the image is put into an XImage, then copied back
out it looses the alpha, so using GetPixel to verify will have the same
problem (it just returns XGetPixel). StretchBlt also does this, but
AlphaBlend does not as its using XRenderSetPictureTransform to stretch
