+ * The bug appears to be triggered if:
+ * 1. There is more than one subpath
+ * 2. All subpaths are axis-aligned rectangles
+ * 3. Only one of the subpaths is within surface bounds
+ *
+ * Tweaking any of the coordinates so that there is at least one
+ * non-axis-aligned segment or removing the second subpath (the one that is
+ * outside the surface bounds) causes the bug to disappear.
