License and Copyright

Disclaimer

Mesa implements various APIs, including OpenGL, OpenGL ES, Vulkan and OpenCL. Even though Mesa implements these APIs, the implementation isn’t formally conformant on all combinations of drivers and hardware. Khronos maintains lists of conformant implementations for each of their APIs, as well as trademark details.

Please do not refer to the library as MesaGL (for legal reasons). It’s just Mesa or The Mesa 3-D graphics library.
