Sorry this is a bit vague. I suppose you're using engine.d or 
screen.d directly right?

Depending on your setup (OpenGL or Software) transparency will be 
different.

For example take a look at line 733, putpixel function and you'll 
see that It handle Color differently if it's OpenGL x Software 
and for the latter it checks if 32bpp or less.

Now if it's OpenGL take a look for "Alpha".
