Hi, I'm new to pygame and I'm exploring the various features. I'm on
Windows, and haven't had any trouble getting HW surfaces (and the great
performance that comes with them). Now I'm playing with per-pixel
alpha. I've managed to get such an image to load and display, but only
as a SW surface. I don't know how to create a HW surface with per-pixel
alpha...whether I can tell image.load() to do it, or if I can convert
it, or what. I tried blitting it to a HW surface, but it didn't retain
the alpha information (which in retrospect makes perfect sense).
Thanks for any help!
