Mesa is an open source 3D computer graphics library that provides a generic OpenGL implementation for rendering three-dimensional graphics on multiple platforms.
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.
