+// ExtendInput effect can extend the input rect, and not just make it smaller.

+// Some effects have different output depending on their input effect's output
+// rect, for example the Border effect (which repeats the edges of its input
+// effect's output rect) or the component transfer and color matrix effects
+// (which can transform transparent pixels into non-transparent ones, but only
+// inside their input effect's output rect).
