-/**
- * Emits an appropriate flush for a BO if it has been rendered to within the
- * same batchbuffer as a read that's about to be emitted.
- *
- * The GPU has separate, incoherent caches for the render cache and the
- * sampler cache, along with other caches.  Usually data in the different
- * caches don't interact (e.g. we don't render to our driver-generated
- * immediate constant data), but for render-to-texture in FBOs we definitely
- * do.  When a batchbuffer is flushed, the kernel will ensure that everything
- * necessary is flushed before another use of that BO, but for reuse from
- * different caches within a batchbuffer, it's all our responsibility.
