Detailed Description

Creates shader objects suitable for use with the Vulkan API.

By default, shaders are created from SPIR-V bytecode. If libglslang support is available and the environment variable MYTHTV_GLSLANG is set, shaders will be compiled from the GLSL source code. libglslang support is currently intended for development use only - i.e. to test and compile shaders.
