Description

Prologue and Epilogue barrier passes are used to plan transitions around RHI render pass merging, as it is illegal to issue a barrier during a render pass. If passes [A, B, C] are merged together, 'A' becomes 'B's prologue pass and 'C' becomes 'A's epilogue pass. This way, any transitions that need to happen before the merged pass (i.e. in the prologue) are done in A. Any transitions after the render pass merge are done in C.
