vlc | branch: master | Romain Vimont <rom1v at videolabs.io> | Thu Jan 23 17:56:55 2020 +0100| [d932092301860ec1b1fe945b5e961242f95be964] | committer: Jean-Baptiste Kempf
opengl: merge prgm into vlc_gl_renderer
The struct prgm contains some locations of the program, the struct
vlc_gl_renderer contains some others.
There are no reason to keep two separate structures.
