IMPORTANT: Some renamings. Will need to be applied carefully to the carbon repository, in the following order: -- pixel_to_char_size -> pixel_to_frame_unit_size -- char_to_pixel_size -> frame_unit_to_pixel_size -- pixel_to_real_char_size -> pixel_to_char_size -- char_to_real_pixel_size -> char_to_pixel_size -- Reverse second and third arguments of change_frame_size() and change_frame_size_1() to try to make functions consistent in putting width before height. -- Eliminate old round_size_to_char, because it didn't really do anything differently from round_size_to_real_char() -- round_size_to_real_char -> round_size_to_char; any places that called the old round_size_to_char should just call the new one. 2. IMPORTANT FOR CARBON: The set_frame_size() method is now passed sizes in "frame units", like all other frame-sizing functions, rather than some hacked-up combination of char-cell units and total pixel size. This only affects window systems that use "pixelated geometry", and I'm not sure if Carbon is one of them. MS Windows is pixelated, X and GTK are not. For pixelated-geometry systems, the size in set_frame_size() is in displayable pixels rather than total pixels and needs to be converted appropriately; take a look at the changes made to mswindows_set_frame_size() method if necessary. 3. Add a big long comment in frame.c describing how frame geometry works. 4. Remove MS Windows-specific character height and width fields, duplicative and unused. 5. frame-displayable-pixel-* and set-frame-displayable-pixel-* didn't use to work on MS Windows, but they do now. 6. In general, clean up the handling of "pixelated geometry" so that fewer functions have to worry about this. This is really an abomination that should be removed entirely but that will have to happen later. Fix some buggy code in frame_conversion_internal() that happened to "work" because it was countered by oppositely buggy code in change_frame_size(). 7. Clean up some frame-size code in toolbar.c and use functions already provided in frame.c instead of rolling its own. 8. Fix check_frame_size() in window.c, which formerly didn't take pixelated geometry into account.

;;; Code:

(defvar use-default-ascent (make-char-table 'generic)
     "UNIMPLEMENTED.
Char table of characters whose ascent values should be ignored.
If an entry for a character is non-nil, the ascent value of the glyph
is assumed to be what specified by _MULE_DEFAULT_ASCENT property of a font.

This affects how a composite character which contains
such a character is displayed on screen.")

(defvar ignore-relative-composition (make-char-table 'generic)
     "UNIMPLEMENTED.
Char table of characters which is not composed relatively.
If an entry for a character is non-nil, a composition sequence
which contains that character is displayed so that
the glyph of that character is put without considering
an ascent and descent value of a previous character.")

(defvar compose-chars-after-function 'compose-chars-after
    "UNIMPLEMENTED.
Function to adjust composition of buffer text.

The function is called with three arguments FROM, TO, and OBJECT.
FROM and TO specify the range of text of which composition should be
adjusted.  OBJECT, if non-nil, is a string that contains the text.

This function is called after a text with `composition' property is
inserted or deleted to keep `composition' property of buffer text
valid.

The default value is the function `compose-chars-after'.")

(defvar composition-function-table (make-char-table 'generic)
    "UNIMPLEMENTED.
Char table of patterns and functions to make a composition.

Each element is nil or an alist of PATTERNs vs FUNCs, where PATTERNs
are regular expressions and FUNCs are functions.  FUNC is responsible
for composing text matching the corresponding PATTERN.  FUNC is called
with three arguments FROM, TO, and PATTERN.  See the function
`compose-chars-after' for more detail.

This table is looked up by the first character of a composition when
the composition gets invalid after a change in a buffer.")

(defun compose-region-internal (start end &optional components mod-func)
  "UNIMPLEMENTED.
Internal use only.

Compose text in the region between START and END.
Optional 3rd and 4th arguments are COMPONENTS and MODIFICATION-FUNC
for the composition.   See `compose-region' for more detial."
  nil)

(defun compose-string-internal (string start end &optional components mod-func)
  "UNIMPLEMENTED.
Internal use only.

Compose text between indices START and END of STRING.
Optional 4th and 5th arguments are COMPONENTS and MODIFICATION-FUNC
for the composition.   See `compose-string' for more detial."
  nil)

(defun find-composition-internal (pos limit string detail-p)
  "UNIMPLEMENTED.
Internal use only.

Return information about composition at or nearest to position POS.
See `find-composition' for more detail."
