Re: GTK+, Cairo, XLib integration for fast 2D graphics drawing

Hi again Chris,

I am attaching the cairo-trace file created on my Fedora 15 laptop
(different specs from the Desktop PC I mentioned in a previous email):

*X Version:*
X.Org X Server 1.10.4
Release Date: 2011-08-19
X Protocol Version 11, Revision 0
Build Operating System: x86-16 2.6.32-131.2.1.el6.x86_64

*X Driver:* radeon
/lib/modules/2.6.40.6-0.fc15.i686/kernel/drivers/gpu/drm/radeon/radeon.ko

*Cairo RPMs Version:
*cairo-1.10.2-3.fc15.i686
cairo-devel-1.10.2-3.fc15.i686

The trace was created as follows:
cairo-trace --profile <application_name>, whereby I loaded a simple
testcase with >100K rectangles, and zoomed in a few times.

Let me know if the trace makes sense.

Thanks for your help!

Christos.
