OpenGL support

By default, OpenGL drivers are not available to programs in Geospatial NIX.env environments. Geospatial NIX provides NixGL wrapper which allows to run OpenGL programs with correctly compiled Intel, AMD and Nouveau GPU drivers using Mesa OpenGL implementation.

Add following line to the configuration to enable OpenGL support

nixgl.enable = true;

and run the program with nixGLIntel prefix

nixGLIntel <program>

For example

nixGLIntel qgis
