 Great work.  The transparent makes more sense.  When you originally said
 black I was thinking why this was being sent down the Composite pipeline
 instead of being a Solid Fill/Clear and a Blit.

 I just went through some change logs and it appears that Cairo is using
 more of the "Render" OpenGL aspects.  As you already figured out Texture
 Mode S/T is GL lingo.

 It used to be common practice that we only ever handled >
 RepeatTypeNormal, and anything else would get punted to software.  Then if
 the operation was < Normal then Cairo would never provide negative
 coordinates.  I guess that got fixed to optimize another graphics driver
 somewhere down the road.

 You should probably send this fix over to the openchrome guys.  I believe
 they have the same bug in their codebase.

 I will test and commit this and provide new rpms.
