;;;; Notes

;;; This is essentially a rewrite/transliteration of Gilbert's original code,
;;; modified to improve performance. This is achieved primarily by using 
;;; read-sequence into an (unsigned-byte 8) array and parsing directly
;;; from this array (the original code read a list of strings using read-line
;;; and further divided these into substrings in various places. It is
;;; substantially faster than the original code, but there are opportunities
;;; to further improve performance by perhaps several times, including:
;;;  - Use an array rather than hash table to resolve color tokens
;;;    (I avoided doing this for now due to a pathological case of a file
;;;     with a small palette but high CPP and sparse color tokens)
;;;  - Stricter type declarations (some but not all of the code assumes cpp<3)
;;;  - In the worst case (photographs), we spent most of our time parsing
;;;    the palette (it may have thousands or millions of entries).
;;;  - For the above case, we should be generating an RGB or RGBA image
;;;    rather than an indexed-pattern (and consing a ton of color objects).
;;;  - People who save photographs in XPM format are morons, so it isn't
;;;    worth optimizing.

;;; Gilbert's Notes:

;; - We lose when the XPM image only specifies colors for say the mono
;;   visual.
;;
;; - We need a little refactoring:
;;
;;   . The list of colors below is now actually the second place we have
;;     that.
;;
;;   . Parsing of #rgb style colors is now the upteens place we have
;;     that in general.
;;
;;   => Put that in utils.lisp and document its interface.
;;
;; - The ASCII-centric approach of XPM makes it suitable for embedding
;;   it into sources files. I want a macro which takes a list of
;;   strings according the XPM format and turns it into a make-pattern
;;   call.
;;
;; - This needs to be incorporated into READ-BITMAP-FILE or what ever
;;   that is called.
;;
;; - We might be interested in the hot spot also.

;;;; Summary of the File Format

;; [as of the XPM-3.4i documentation by Arnaud Le Hors].

;; | The XPM Format
;; | 
;; | The XPM format presents a C syntax, in order to provide the ability to
;; | include XPM files in C and C++ programs. It is in fact an array of
;; | strings composed of six different sections as follows:
;; | 
;; | /* XPM */
;; | static char* <variable_name>[] = {
;; | <Values>
;; | <Colors>
;; | <Pixels>
;; | <Extensions>
;; | };
;; | 
;; | The words are separated by a white space which can be composed of
;; | space and tabulation characters. The <Values> section is a string
;; | containing four or six integers in base 10 that correspond to: the
;; | pixmap width and height, the number of colors, the number of
;; | characters per pixel (so there is no limit on the number of colors),
;; | and, optionally the hotspot coordinates and the XPMEXT tag if there is
;; | any extension following the <Pixels> section.
;; | 
;; | <width> <height> <ncolors> <cpp> [<x_hotspot> <y_hotspot>] [XPMEXT]
;; | 
;; | The Colors section contains as many strings as there are colors, and
;; | each string is as follows:
;; | 
;; | <chars> {<key> <color>}+
;; | 
;; | Where <chars> is the <chars_per_pixel> length string (not surrounded
;; | by anything) representing the pixels, <color> is the specified color,
;; | and <key> is a keyword describing in which context this color should
;; | be used. Currently the keys may have the following values:
;; | 
;; |     m  for mono visual
;; |     s  for symbolic name
;; |     g4 for 4-level grayscale
;; |     g  for grayscale with more than 4 levels
;; |     c  for color visual
;; | 
;; | Colors can be specified by giving the colorname, a # followed by the
;; | RGB code in hexadecimal, or a % followed by the HSV code (not
;; | implemented). The symbolic name provides the ability of specifying the
;; | colors at load time and not to hardcode them in the file.
;; | 
;; | Also the string None can be given as a colorname to mean
;; | ``transparent''. Transparency is supported by the XPM library by
;; | providing a masking bitmap in addition to the pixmap. This mask can
;; | then be used either as a clip-mask of an Xlib GC, or a shape-mask of a
;; | window using the X11 Nonrectangular Window Shape Extension [XShape]. 
;; | The <Pixels> section is composed by <height> strings of <width> *
;; | <chars_per_pixel> characters, where every <chars_per_pixel> length
;; | string must be one of the previously defined groups in the <Colors>
;; | section.
;; | 
;; | Then follows the <Extensions> section which must be labeled, if not
;; | empty, in the <Values> section as previously described. This section
;; | may be composed by several <Extension> subsections which may be of two
;; | types:
;; | 
;; |   . one stand alone string composed as follows:
;; | 
;; |     XPMEXT <extension-name> <extension-data>
;; | 
;; |   . or a block composed by several strings:
;; | 
;; |     XPMEXT <extension-name>
;; |     <related extension-data composed of several strings>
;; | 
;; | Finally, if not empty, this section must end by the following string:
;; | 
;; | XPMENDEXT
;; | 
;; | Extensions can be used to store any type of data one might want to
;; | store along with a pixmap, as long as they are properly encoded so
;; | they do not conflict with the general syntax. To avoid possible
;; | conflicts with extension names in shared files, they should be
;; | prefixed by the name of the company. This would ensure uniqueness.
