Detailed Description

OpenGL Commands Processing Thread.

Continuosly executes OpenGL commands

Every OSD draw or flush which is invoked by VDR is transposed into an OpenGL command. cOglThread holds a fifo-queue of these commands. It continuosly checks for commands on the queue, pops them and sends them to the hardware.

On startup it initiates all necessary OpenGL bits.
