+ *
+ * This function tries to implement option 1, under the assumption that the
+ * correct way to reverse the effects of SetLayout is to translate the rect
+ * such that the offset from the DC bitmap's left edge to the old rect's
+ * left edge is equal to the offset from the DC bitmap's right edge to the
