+/* Fringe bitmaps are represented in three different ways:
+
+ Logical bitmaps are used internally to denote things like
+ 'end-of-buffer', 'left-truncation', 'overlay-arrow', etc.
+
+ Physical bitmaps specify the visual appearence of the bitmap,
+ e.g. 'bottom-left-angle', 'left-arrow', 'left-triangle', etc.
+ User defined bitmaps are physical bitmaps.
+
+ Internally, fringe bitmaps for a specific display row are
+ represented as a simple integer that is used as an index
+ into the table of all defined bitmaps. This index is stored
+ in the `fringe' property of the physical bitmap symbol.
+
+ Logical bitmaps are mapped to physical bitmaps through the
+ buffer-local `fringe-indicator-alist' variable.
+
+ Each element of this alist is a cons (LOGICAL . PHYSICAL)
+ mapping a logical bitmap to a physical bitmap.
+ PHYSICAL is either a symbol to use in both left and right fringe,
+ or a cons of two symbols (LEFT . RIGHT) denoting different
+ bitmaps to use in left and right fringe.
+
+ LOGICAL is first looked up in the window's buffer's buffer-local
+ value of the fringe-indicator-alist variable, and if not present,
+ in the global value of fringe-indicator-alist.
+
+ If LOGICAL is not present in either alist, or the PHYSICAL value
+ found is nil, no bitmap is shown for the logical bitmap.
+
+ The `left-fringe' and `right-fringe' display properties
+ must specify physical bitmap symbols.
