Description

This extension allows the separate compilation of four distinct parts of graphics pipelines, with the intent of allowing faster pipeline loading for applications reusing the same shaders or state in multiple pipelines. Each part can be independently compiled into a graphics pipeline library, with a final link step required to create an executable pipeline that can be bound to a command buffer.
