+**Mesa** is an open source 3D computer graphics library that provides a generic OpenGL implementation for rendering three-dimensional graphics on multiple platforms.
   * Mesa provides open source software implementation of OpenGL, Vulkan, and some other graphics API specifications for Intel and AMD graphics hardware.

   * With Mesa, you can play high-end games and use applications that require such graphics libraries.

+Mesa uses card-specific drivers to translate the API into a hardware-specific form.

+Modern display servers and window managers like X.Org and Wayland use OpenGL internally, so all the graphics go through Mesa.
