Why is this change needed? Seems unrelated.

To make every tile not solid color, ie so blocking raster/upload does something.

-    SkPaint paint;
-    canvas->drawRectCoords(draw_rect.x(),
-                           draw_rect.y(),
-                           draw_rect.right(),
-                           draw_rect.bottom(),
-                           paint);
+    bool red = true;
+    while (!draw_rect.IsEmpty()) {
+      SkPaint paint;
+      paint.setColor(red ? SK_ColorRED : SK_ColorBLUE);
+      canvas->drawRect(gfx::RectFToSkRect(draw_rect), paint);
+      draw_rect.Inset(1, 1);
+    }
   }
 }
