## Detailed Description

Additional features not specified by GLSL specification.

EXT extensions are fully tested and documented.

Even if it's highly unrecommended, it's possible to include all the extensions at once by including <glm/ext.hpp>. Otherwise, each extension needs to be included a specific file.
