The pipeline cache contains three separate hash tables, one for the state affecting the vertex shaders, one for the fragment shaders and one for the resulting combined program. Previously these hash tables had a fair bit of duplicated code to calculate the hashes, check for equality and copy the pipeline when it is added. This patch moves the common bits of code to a new type called CoglPipelineHashTable which just wraps a GHashTable with a given set of state flags to use for hashing and checking for equality.
