50 Glyphs

A glyph is an object that is used for pixmaps, widgets, and images of all sorts, as well as for things that “act” like pixmaps, such as non-textual strings (annotations) displayed in a buffer or in the margins. It is used in begin-glyphs and end-glyphs attached to extents, marginal and textual annotations, overlay arrows (overlay-arrow-* variables), toolbar buttons, mouse pointers, frame icons, truncation and continuation markers, and the like. Basically, any place there is an image or something that acts like an image, there will be a glyph object representing it.
