http://build.webkit.org/results/Lion%20Debug%20(Tests)/r112736%20(5114)/results.html shows two WebGL tests failing: fast/canvas/webgl/framebuffer-object-attachment.html fast/canvas/webgl/object-deletion-behaviour.html I'll skip them.
<rdar://problem/13417102>
Only fast/canvas/webgl/framebuffer-object-attachment.html fails now.
fast/canvas/webgl/object-deletion-behaviour.html is still failing on Lion Debug WK1.
