Upgrade Mesa renderer used by cc pixel tests

Project Member Reported by ccameron@chromium.org, Feb 1 2017 
For wide gamut, high bit depth, and HDR, we will be using half-float textures in chrome's compositor.

The chrome compositor pixel tests use the mesa renderer, which is currently at Mesa 9.0.3, OpenGL 2.1, with no half-float extensions.

We need to upgrade Mesa to a more modern version, so that we can test this work.

Rather than upgrade this Mesa snapshot, we should focus our efforts on integrating SwiftShader into Chromium. This effort is close to being complete, and we should collectively help it along rather than wasting time upgrading Mesa again when the long-term goal is to remove that third-party dependency.

Hi Chris, SwiftShader currently supports GL_OES_texture_half_float, GL_OES_texture_half_float_linear, and GL_EXT_color_buffer_half_float. Will that work for your compositor pixel tests or do you need anything else?

That should do!
