He's using the simpledisplay.d lib which DOES NOT SUPPORT
transparency in its drawImage function. It does NOT use opengl
functions and are not compatible with them.
To do opengl stuff with simpledisplay, there is a separate flow.
You use opengl functions on a redraw scene delegate instead of
using any of the Image or Painter objects. It is quite different
and there is no easy fix on that end.
but the gdi+ functions in sdpy MIGHT be able to be ported to
alpha blend on Windows easily enough. I just haven't gotten
around to it yet.
