Whiteboard
Meta:
Headline: Add full cairo-gles2 support for platforms not supporting GL_OES_texture_npot (e.g. SGX and Tegra) by implementing repeat wrap modes in shaders.
Acceptance: Results of cairo-test-suite using shader-side repeat wrap modes for platforms that don't support NPOT are comparable to those of platforms having native NPOT support. No regressions on platforms supporting NPOT.
