[Mesa-dev] [PATCH 3/4] drirc: add workarounds for Unigine Tropics v2

[Martin Peres]

v2:
- rename mesa_extension-override to extension_override
- improve the comment by telling we disable GL_ARB_gpu_shader5
- fix the name ARB_GL_gpu_shader5 to GL_ARB_gpu_shader5 (Ilia)

   Enabling all extensions for Unigine fixes most issues, but the GLSL version

+* Unigine Tropics 1.3 makes use of the "sample" keyword which is reserved
+  with GL_ARB_gpu_shader5 which got enabled by force_glsl_extensions_warn.
+  Disable this extension using extension_override.
+  It also makes use of bitwise manipulation (when adding anistropic filtering)
+  which is illegal in GLSL 1.10. Adding "#version 130" fixes this.

 * Unigine Heaven 3.0 with ARB_texture_multisample uses a "ivec4 * vec4"
   expression, which is illegal in GLSL 1.10.
   Adding "#version 130" fixes this.
