Sorry for the OT :
apropos AlphaBlend and RGBA bitmaps... what happens with BitBlt on
a destination DIB which has alpha channel ? it gets overwritten or
the dest alpha channel is simply ignored ?
I mean
BitBlt(dstBmp......., SRC_COPY)  what happens to dstBmp alpha ?
and
BitBlt(dstBmp......., SRC_AND)   ???
