- * GrBatch is the base class for all Ganesh deferred geometry generators. To facilitate
- * reorderable batching, Ganesh does not generate geometry inline with draw calls. Instead, it
- * captures the arguments to the draw and then generates the geometry on demand. This gives GrBatch
- * subclasses complete freedom to decide how / what they can batch.
- *
- * Batches are created when GrContext processes a draw call. Batches of the same subclass may be
- * merged using combineIfPossible. When two batches merge, one takes on the union of the data
- * and the other is left empty. The merged batch becomes responsible for drawing the data from both
- * the original batches.
- *
- * If there are any possible optimizations which might require knowing more about the full state of
- * the draw, ie whether or not the GrBatch is allowed to tweak alpha for coverage, then this
- * information will be communicated to the GrBatch prior to geometry generation.
