Comment:
It may work for ShowImage now, but I don't remember if I implemented
B_OP_BLEND as drawing mode which can be passed to the BView method that
creates a draw bitmap. If not, it could be simulated easily: On the
app_server side, the drag bitmap is temporarily combined with the cursor
bitmap. At this step, any necessary transformation can be performed as the
bitmap is converted to RGBA color space anyway. For B_OP_BLEND, the alpha
channel could simply be divided by two. I am undecided whether to close
the ticket, since there may be no applications left that use B_OP_BLEND
instead of B_OP_ALPHA, so this missing feature may not be user visible.
Ok, let's close the ticket, since it is specifically about ShowImage.
