   Enabling all extensions for Unigine fixes most issues, but the GLSL version
   is still 1.10.
 
+* Unigine Tropics 1.3 makes use of the "sample" keyword which is reserved
+  with ARB_GL_gpu_shader5 which got enabled by force_glsl_extensions_warn.
+  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.
