- * The GrPrimitiveProcessor represents some kind of geometric primitive.  This includes the shape
- * of the primitive and the inherent color of the primitive.  The GrPrimitiveProcessor is
- * responsible for providing a color and coverage input into the Ganesh rendering pipeline.  Through
- * optimization, Ganesh may decide a different color, no color, and / or no coverage are required
- * from the GrPrimitiveProcessor, so the GrPrimitiveProcessor must be able to support this
- * functionality.  We also use the GrPrimitiveProcessor to make batching decisions.
- *
- * There are two feedback loops between the GrFragmentProcessors, the GrXferProcessor, and the
- * GrPrimitiveProcessor.  These loops run on the CPU and compute any invariant components which
- * might be useful for correctness / optimization decisions.  The GrPrimitiveProcessor seeds these
- * loops, one with initial color and one with initial coverage, in its
- * onComputeInvariantColor / Coverage calls.  These seed values are processed by the subsequent
- * stages of the rendering pipeline and the output is then fed back into the GrPrimitiveProcessor in
- * the initBatchTracker call, where the GrPrimitiveProcessor can then initialize the GrBatchTracker
- * struct with the appropriate values.
- *
- * We are evolving this system to move towards generating geometric meshes and their associated
- * vertex data after we have batched and reordered draws.  This system, known as 'deferred geometry'
- * will allow the GrPrimitiveProcessor much greater control over how data is transmitted to shaders.
- *
- * In a deferred geometry world, the GrPrimitiveProcessor can always 'batch'  To do this, each
- * primitive type is associated with one GrPrimitiveProcessor, who has complete control of how
- * it draws.  Each primitive draw will bundle all required data to perform the draw, and these
- * bundles of data will be owned by an instance of the associated GrPrimitiveProcessor.  Bundles
- * can be updated alongside the GrBatchTracker struct itself, ultimately allowing the
- * GrPrimitiveProcessor complete control of how it gets data into the fragment shader as long as
- * it emits the appropriate color, or none at all, as directed.

+ * from the GrPrimitiveProcessor, so the GrPrimitiveProcessor must be able to support this
+ * functionality.  We also use the GrPrimitiveProcessor to make batching decisions.
+ *
+ * There are two feedback loops between the GrFragmentProcessors, the GrXferProcessor, and the
+ * GrPrimitiveProcessor.  These loops run on the CPU and compute any invariant components which
+ * might be useful for correctness / optimization decisions.  The GrPrimitiveProcessor seeds these
+ * loops, one with initial color and one with initial coverage, in its
+ * onComputeInvariantColor / Coverage calls.  These seed values are processed by the subsequent
+ * stages of the rendering pipeline and the output is then fed back into the GrPrimitiveProcessor in
+ * the initBatchTracker call, where the GrPrimitiveProcessor can then initialize the GrBatchTracker
+ * struct with the appropriate values.
+ *
+ * We are evolving this system to move towards generating geometric meshes and their associated
+ * vertex data after we have batched and reordered draws.  This system, known as 'deferred geometry'
+ * will allow the GrPrimitiveProcessor much greater control over how data is transmitted to shaders.
+ *
+ * In a deferred geometry world, the GrPrimitiveProcessor can always 'batch'  To do this, each
+ * primitive type is associated with one GrPrimitiveProcessor, who has complete control of how
+ * it draws.  Each primitive draw will bundle all required data to perform the draw, and these
+ * bundles of data will be owned by an instance of the associated GrPrimitiveProcessor.  Bundles
