[Mesa-dev] [RFC 00/11] GL_ARB_gpu_shader_fp64

[Elie Tournier]

From: Elie Tournier <elie.tournier at collabora.com>

This series is based on Ian's work about GL_ARB_gpu_shader_int64 [1].
The goal is to expose GL_ARB_shader_fp64 to OpenGL 3.0 GPUs.

Each function can be independently tested using shader_runner from piglit.
The piglit files are stored on github [2].
