Is the Win32 software implementation noticeably faster than the
libpixman one? Is the libpixman implementation you are using
compiled with or without fbmmx?

(As far as I remember, a surface with destination alpha is always
a memory surface.)

Is there any documentation that AlphaBlend handles destination
alpha? I see nothing about that in the msdn docs.
