Cairo makes it not about pixels anymore...

Anyhow looks great now. Haven't found any bugs in the aperture macro
stuff yet. Not that I have looked that closely. I fixed the aperture
macro drawing for the GDK target and it is in the CVS now.

Then, is the next step to start implementing the "aperture macro
optimizer"? I think I will add a function in amacro.c that handles
conversion of AD with AM to just apertures. What do you think?

I hope we handle them correct. When I read the gerber definition paper I
get really confused. Some things I have never seen used in actual gerber
files and I think it is because no-one really understands how it is
intended to work.
