So 6.5.1 is out, cool! May I ask for your attention to the
mesa-cvs-r300-smooth-line.patch patch which is in the SRPM I "attached" too:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=201365

Get the SRPM directly here:
http://people.atrpms.net/~hdegoede/mesa-6.5-20060802.src.rpm

This might be a good starting point for the patchset as it contains the
patchset in Fedora's SRPM ported to a pretty rescent mesa-CVS.

Anyways this patch does the following (as described in the referenced BZ
ticket):

---

There is one peculiar patch in my SRPM which needs some clarification:
mesa-cvs-r300-smooth-line.patch

This comments this 1 line in r300_renderer.c:
FALLBACK_IF(ctx->Line.SmoothFlag); // GL_LINE_SMOOTH

the result of this is that if an application has requested anti-aliased
lines,
which currently are not implemented in the r300 driver, the application gets
normal (not antialiased) lines instead of falling back to the software
renderer.

This patch is needed to make googleearth and smc
(http://www.secretmaryo.org/)
usable IMHO having none antialiased lines is way better then 2 fps.

The same could be argued for anti-aliased points (the line below this
one), but
I haven't encountered any apps using this one yet.

Notice that this change was suggested by upstream and that upstream has even
concidered doing this themselves, they haven;t however because they are
planning
to fix this by actually implementing antialiased lines soon.

Thanks & Regards,

Hans
