+ * added image config suffix ".class" to be able to define classes of
+ crumbled elements which are then separated against each others when
+ drawing crumbled borders (class names can freely be defined)
+ * added image config suffix ".style" to use two new features for
+ crumbled graphics:
+ - "accurate_borders": try to draw correctly crumbled corners
+ - "inner_corners": also draw inner corners -- this is a big kludge:
+ number of frames for crumbled graphic must be "2", with the first
+ frame as usual (crumbled graphic), while the second frame contains
+ the inner corners for the crumbled graphic
+ (These two features are mainly intended for bevelled walls, not for
+ diggable elements like sand; "inner_corners" only reliably works for
+ static walls, not for dynamically changing walls using CEs.)
