| The GL Vendor-Neutral Dispatch library |
| |
| libglvnd is a vendor-neutral dispatch layer for arbitrating |
| OpenGL API calls between multiple vendors. It allows multiple |
| drivers from different vendors to coexist on the same |
| filesystem, and determines which vendor to dispatch each API |
| call to at runtime. |
| |
| Both GLX and EGL are supported, in any combination with OpenGL |
| and OpenGL ES. |
