// Both ConvolveMatrix and Lighting filters have an interaction of edge mode and
// source rect that is a bit tricky with D2D1 effects. We want the edge mode to
// only apply outside of the render rect. So if our input surface or filter is
// smaller than the render rect, we need to add transparency around it until we
// reach the edges of the render rect, and only then do any repeating or edge
// duplicating. Unfortunately, the border effect does not have a render rect
// attribute - it only looks at the output rect of its input filter or
// surface. So we use our custom ExtendInput effect to adjust the output rect of
// our input. All of this is only necessary when our edge mode is not
// EDGE_MODE_NONE, so we update the filter chain dynamically in UpdateChain().
