Why GTK2 "screen" not supports alpha?
It is strange because if I load PNG with transparency (image with
gradient) into TImage then I clearly can see alpha blending effect on
GTK2 when image is diplayed.
Iirc (its long ago when i implemented it) the alphablending is done by the
underlying rawimage implementation
Marc
I tried to put 32 bit image in to TImage (on GTK2) and alphablending
works. Is this means that I can always put an image with 32 bit depth in
to TImage when "GetDescriptionFromDevice(0)" says "screen" supports
"Depth: 24"? If not always then how to know when I can?
