Support more GLSL output versions from the shader translators #1044

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Currently the shader translator only supports GLSL version 130, 150, 410 and 
420.  Update it to support as many GLSL versions as possible so that the GL 
renderer can support ES3 on the lowest possible GL version.

Refactor GLSL version calculations for emulated functions.

Pass the target GLSL version to InitBuiltInFunctionEmulatorForGLSL so that
it can be updated to generate emulated functions for multiple versions.

Improve the test precision in PackUnpackTest.

 * Output to floating point framebuffers so that results are not truncated
   to 8 bit normalized values.
 * Tighten the epsilon from 1/255 to 0.0005. May need further tweaking as
   more GPUs are tested.
 * Explicitly check for -inf and inf values when they were previously
   rounded to 0 and 255.
 * Explicitly check for clamping of overflowed normalized floats by
   providing the expectations instead of computing them.

Remove the PackUnpackHalfOverflow test.

Different drivers handle overflow differently.  The overflow case is not
defined in the spec.
