The CoglPipelineCache is now extended to store templates for state affecting vertex shaders and combined programs. The GLSL fragend, vertend and progend now uses this to get cached shaders and a program. When a new pipeline is created it will now get hashed three times if the GLSL backends are in use (once for the fragend, once for the vertend and once for the progend). Ideally we should add some way for the progend to check its cache before the fragends and vertends are checked so that it can bypass them entirely if it can find a cached combined program.
