Detailed Description

Implementation file for CPU/GPU device selection.

Introduces a global variable which value indicates whether GPU acceleration is enabled. The value of this global variable can be forced to GPU-disable by setting the value of environment variable DISABLE_GPU_ACCELERATION to 1. The value of environment variable DISABLE_GPU_ACCELERATION is red by a global constructor (at the moment when AFW library is loaded).
