Where's that CL? :)

That's what I keep wondering :-\

     GrDeviceCoordTexture dstCopy;
-    if (!this->setupDstReadIfNecessary(&dstCopy, &devBounds)) {
+    if (!this->setupDstReadIfNecessary(&dstCopy, NULL)) {
         return;
     }
 
-    this->onDrawPaths(pathCount, paths, transforms, fill, stroke,
+    this->onDrawPaths(pathRange, indices, count, transforms, transformsFormat, fill,
                       dstCopy.texture() ? &dstCopy : NULL);
 }
