[cairo] Cairo problems on Solaris

[dhollen at mosis.org]

I'm trying to run GTK+2.8.8 with Cairo 1.0.2 on a Solaris 9 host and
I'm running into several problems.  I thought people should be aware
that there are still some significant issues on Solaris hosts that
prevent upgrading to GTK+2.8.  I'm assuming the problems are related
to Cairo, rather than some other component.

Issues I have run into:

1. gtk-demo seg faults for some graphics cards and root window depths.  
2. Red and blue color components are switched for some graphics cards
   (text drawn in blue appears red and vice versa).
3. Performance is noticeably slower than GTK+2.6 for some graphics cards.

Here is a summary of my observations.
   	
   Graphics Card	Planes  GTK-demo   Red-blue  Performance
   -------------	------  --------   --------  -----------
   single-buffered FFB1	 8 	Seg fault  Switched  OK
   Expert3D-Lite	 8 	Seg fault  OK	     Slow
   XVR-1000		 8 	Seg fault  OK	     OK
   single-buffered FFB1	24 	OK	   Switched  OK
   Expert3D-Lite	24 	OK	   OK	     Slow
   XVR-600		24 	OK	   OK	     OK

I think the seg fault problem has already been reported

	https://bugs.freedesktop.org/show_bug.cgi?id=4505

but until it is fixed, it is hard to report other bugs since I can't
easily provide an example that demonstrates wrong behavior.  The
available evidence seems to indicate that the seg fault problem occurs
for me only when the root window is 8 planes.  Hopefully, this will be
fixed soon.

The switch of red and blue color components has only been observed
on one graphics card (single-buffered FFB1).  I have been told this
is built into the motherboard (it is on an Ultra-2).

Slow performance has only been observed on Expert3D-Lite graphics card
(significantly slower than GTK+2.6).
