primus-libs 0~20150328-13 (arm64 binary) in ubuntu hirsute

 Primus is a shared library that provides OpenGL and GLX APIs and implements
 low-overhead local-only client-side OpenGL offloading via GLX forking,
 similar to VirtualGL. It intercepts GLX calls and redirects GL rendering
 to a secondary X display, presumably driven by a faster GPU. On swapping
 buffers, rendered contents are read back using a PBO and copied onto
 the drawable it was supposed to be rendered on in the first place.
 .
 This package contains the libraries for primus which are loaded when running
 primusrun.
