Detailed Description

ScratchBuffer represents a GPU buffer object that is allowed to be reused across strictly sequential tasks within a Recording. It can be used to sub-allocate multiple bindings. When a ScratchBuffer gets deallocated, the underlying GPU buffer gets returned to the originating DrawBufferManager for reuse.
