We've continued the analysis from 
https://bugs.webkit.org/show_bug.cgi?id=54458#c7
and worked with Chris Wilson to address some of these issue. 

We've experimentally bumped cairo to 1.12 which has introduced new regressions:
fast/canvas/canvas-fillRect-gradient-shadow.html = TEXT
svg/batik/text/smallFonts.svg = TEXT
svg/batik/text/textGlyphOrientationHorizontal.svg = TEXT
svg/batik/text/textOnPath2.svg = TEXT
svg/batik/text/textOnPath3.svg = TEXT
svg/batik/text/textOnPathSpaces.svg = TEXT
svg/batik/text/verticalTextOnPath.svg = TEXT
svg/hixie/perf/001.xml = TEXT
svg/hixie/perf/002.xml = TEXT
svg/stroke/zero-length-path-linecap-rendering.svg = TEXT
svg/stroke/zero-length-subpaths-linecap-rendering.svg = TEXT
svg/transforms/transformed-text-fill-pattern.html = IMAGE

For which we filed 
https://bugs.freedesktop.org/show_bug.cgi?id=54446 "WebKit regression observed in Cairo commit 83bfd85"  (now resolved)
https://bugs.freedesktop.org/show_bug.cgi?id=54507 "WebKit regression found in Cairo commit 51594d9" (under investigation)

Once the second bug can be resolved (on either cairo side or WebKit side), we should be able to bump Cairo to at least f34b87f6d76cbea93acd4a8c73c8c6a6b412a302 or a release version after this commit.

This would resolve failures for (no webkit bugs):

2d.path.rect.selfintersect.html
canvas/philip/tests/2d.path.rect.zero.6.html
canvas/philip/tests/2d.path.arc.zeroradius.html

WebKit Bug 54471:
canvas/philip/tests/2d.path.arc.selfintersect.1.html
canvas/philip/tests/2d.path.arc.shape.3.html
