any hints how to add new glyph-types?

any hints how to add new glyph-types?

[joakim]

I'm reading the display code trying to understand how to add a new glyph
type. It's not completely obvious.

Any hints how to add a new glyph type, somewhat similar to images?

What's a glyph type? what other glyph types do you see in the code?

From dispextern.h:

/***********************************************************************
				Glyphs
 ***********************************************************************/

/* Enumeration of glyph types.  Glyph structures contain a type field
   containing one of the enumerators defined here.  */

enum glyph_type
{
  /* Glyph describes a character.  */
  CHAR_GLYPH,

  /* Glyph describes a composition sequence.  */
  COMPOSITE_GLYPH,

  /* Glyph describes an image.  */
  IMAGE_GLYPH,

  /* Glyph is a space of fractional width and/or height.  */
  STRETCH_GLYPH
};
