Make more tests. Create a surface with an alpha channel and blit it to
a non alpha surface (we need this a lot). This is much slower.

I use 800 MHz which is ok for video playback. I guess it doesn't make
sense to require a higher cpu only for the gui when mplayer can handle
everything with less power. And some people use a mini-itx. It's top
is 1.2 GHz right now.
But the gui redesign will still support pygame. But it would prefer
other backends if they are installed. Why use pygame when imlib2 or
gtkpixbuf support is possible? And one other reason why I don't like
pygame: it has no support for an external main loop. People start to
hate the sleep(0.01) we do in our main loop. They ask, why not use
select? Because I can't get a file descriptor from pygame, I need
active waiting. Very bad.
