1c46dd6417 Cairo backend: 
-DPSsetflat: and -DPScurrentflat should not have been transforming
the flatness value with the current transformation matrix.
The effect of this could be seen in the Apple BezierPathLab example;
zooming in on the circle caused it to look more and more like a
polygon.

Also set NSBezierPath default flatness to 0.6 to match OS X
(it was 1.0, which made circles look a bit rough)

09ce663feb AlpenStep stuff with Fred Kiefer's help: 
- Added support for 32 bit surfaces when it's possible (use of Xrender extension..).
- Modified the Cairo backend to take advantage of that: we can now draw windows with partial transparency.
- Fixed a bug in the Cairo backend (copy of a surface to itself) using the cairo "groups". Scrolling is still wrong, but we're closer to something good ;-)
