The uniform stuff seems very bug-prone, there's 4 nearly identical repetitions
in CCRenderSurface.cpp. I also suspect that you're leaking programs.

Can you document what this does when all points are colinear?
> Source/WebCore/platform/graphics/chromium/LayerRendererChromium.h:225
> + OwnPtr<CCRenderSurface::MaskProgramAA> m_renderSurfaceMaskProgramAA;
> + OwnPtr<CCRenderSurface::ProgramAA> m_renderSurfaceProgramAA;
if you're adding new programs you need to add cleanup code to
LayerRendererChromium::cleanupSharedObjects(). You should hit ASSERTs in debug
mode, have you run the tests in debug?

this is so horribly repetitive and error-prone. is there any better way to do
this?
