  Message : Implement ES2 backend for Angle translator. With this CL, we have the option to select a code output backend: GLSL, GLSL ES, or HLSL. Note that we always emit the highest supported float precision for fragment shader due to anglebug 168. Although this is a temporary solution, it's not against GLSL ES spec, because it's ok for implementation to upgrade precision. Tested with WebGL conformance test suite, GLES2 conformance test suite (only failed 2/1198), and a few webgl demos, including worlds of webgl, aquarium, etc. anglebug=81 test=translator emitting correct GLSL ES code when ES2 backend is selected.
