'progend' is short for 'program backend'. The progend is intended to operate on combined state from a fragment backend and a vertex backend. The progend has an 'end' function which is run whenever the pipeline is flushed and the two pipeline change notification functions. All of the progends are run whenever the pipeline is flushed instead of selecting a single one because it is possible that multiple progends may be in use for example if the vertends and fragends are different. The GLSL progend will take the shaders generated by the fragend and vertend and link them into a single program. The fragend code has been changed to only generate the shader and not the program. The idea is that pipelines can share fragment shader objects even if their vertex state is different. The authority for the progend needs to be the combined authority on the vertend and fragend state. |
