nx-X11 Render extension wire protocol
NX is a software suite which implements very efficient compression of the X11 protocol. This increases performance when using X applications over a network, especially a slow one.
This package provides development headers describing the wire protocol for the Render extension, used to implement Porter-Duff operations within X.
