Fixes for bitmap mask files handling
src/ChangeLog addition:
2010-02-24 Didier Verna <didier@xemacs.org>
* glyphs.c: Clarify comment about potential_pixmap_file_instantiator.
* glyphs.c (xbm_mask_file_munging): Clarify comment, remove
unreachable condition and provide a cuple of assertions.
* glyphs.c (xbm_normalize): Clarify comments, error on mask file
not found.
* glyphs.c (xface_normalize): Ditto, and handle inline data properly.

| 29 Heavily modified / rewritten by Andy Piper. | |
| 30 | |
| 31 Earliest glyph support, Jamie Zawinski for 19.8? | |
| 32 subwindow support added by Chuck Thompson | |
| 33 additional XPM support added by Chuck Thompson | |
| 34 initial X-Face support added by Stig | |
| 35 Majorly rewritten/restructured by Ben Wing, including creation of | |
| 36 glyph and image-instance objects, for 19.12/19.13 | |
| 37 GIF/JPEG/etc. support originally in this file -- see glyph-eimage.c | |
| 38 Pointer/icon overhaul, more restructuring by Ben Wing for 19.14 | |
| 39 Many changes for color work and optimizations by Jareth Hein for 21.0 | |
| 40 Switch of GIF/JPEG/PNG to new EImage intermediate code by Jareth Hein for 21.0 | |
| 41 TIFF code by Jareth Hein for 21.0 | |
| 42 Generalization for ms-windows by Andy Piper for 21.0 | |

| 1555 Image-instance objects encapsulate the way a particular image (pixmap, | |
| 1556 etc.) is displayed on a particular device. In most circumstances, you | |
| 1557 do not need to directly create image instances; use a glyph instead. | |
| 1558 However, it may occasionally be useful to explicitly create image | |
| 1559 instances, if you want more control over the instantiation process. | |
| 1560 | |
| 1561 DATA is an image instantiator, which describes the image; see | |
| 442 | 1562 `make-image-specifier' for a description of the allowed values. |
| 428 | 1563 |
| 1564 DEST-TYPES should be a list of allowed image instance types that can | |
| 1565 be generated. The recognized image instance types are | |
| 1566 | |
| 2959 | 1567 `nothing' |
| 428 | 1568 Nothing is displayed. |
| 2959 | 1569 `text' |
| 428 | 1570 Displayed as text. The foreground and background colors and the |
| 1571 font of the text are specified independent of the pixmap. Typically | |
| 1572 these attributes will come from the face of the surrounding text, | |
| 1573 unless a face is specified for the glyph in which the image appears. | |
| 2959 | 1574 `mono-pixmap' |
| 428 | 1575 Displayed as a mono pixmap (a pixmap with only two colors where the |
| 1576 foreground and background can be specified independent of the pixmap; | |
| 1577 typically the pixmap assumes the foreground and background colors of | |
| 1578 the text around it, unless a face is specified for the glyph in which | |
| 1579 the image appears). | |
| 2959 | 1580 `color-pixmap' |
| 428 | 1581 Displayed as a color pixmap. |
| 2959 | 1582 `pointer' |
| 428 | 1583 Used as the mouse pointer for a window. |
| 2959 | 1584 `subwindow' |
| 428 | 1585 A child window that is treated as an image. This allows (e.g.) |
| 1586 another program to be responsible for drawing into the window. | |
| 2959 | 1587 `widget' |
| 428 | 1588 A child window that contains a window-system widget, e.g. a push |
| 442 | 1589 button, text field, or slider. |
| 1590 | |
| 1591 The DEST-TYPES list is unordered. If multiple destination types are | |
| 1592 possible for a given instantiator, the "most natural" type for the | |
| 1593 instantiator's format is chosen. (For XBM, the most natural types are | |
| 1594 `mono-pixmap', followed by `color-pixmap', followed by `pointer'. For | |
| 1595 the other normal image formats, the most natural types are | |
| 1596 `color-pixmap', followed by `mono-pixmap', followed by `pointer'. For | |
| 1597 the string and formatted-string formats, the most natural types are | |
| 1598 `text', followed by `mono-pixmap' (not currently implemented), | |
| 1599 followed by `color-pixmap' (not currently implemented). For MS | |
| 1600 Windows resources, the most natural type for pointer resources is | |
| 1601 `pointer', and for the others it's `color-pixmap'. The other formats | |
| 1602 can only be instantiated as one type. (If you want to control more | |
| 1603 specifically the order of the types into which an image is | |
| 1604 instantiated, just call `make-image-instance' repeatedly until it | |
| 1605 succeeds, passing less and less preferred destination types each | |
| 1606 time.) | |
| 1607 | |
| 1608 See `make-image-specifier' for a description of the different image | |
| 1609 instantiator formats. | |
| 428 | 1610 |
| 1611 If DEST-TYPES is omitted, all possible types are allowed. | |
| 1612 | |
| 442 | 1613 DOMAIN specifies the domain to which the image instance will be attached. |
| 1614 This domain is termed the \"governing domain\". The type of the governing | |
| 1615 domain depends on the image instantiator format. (Although, more correctly, | |
| 1616 it should probably depend on the image instance type.) For example, pixmap | |
| 1617 image instances are specific to a device, but widget image instances are | |
| 1618 specific to a particular XEmacs window because in order to display such a | |
| 1619 widget when two windows onto the same buffer want to display the widget, | |
| 1620 two separate underlying widgets must be created. (That's because a widget | |
| 1621 is actually a child window-system window, and all window-system windows have | |
| 1622 a unique existence on the screen.) This means that the governing domain for | |
| 1623 a pixmap image instance will be some device (most likely, the only existing | |
| 1624 device), whereas the governing domain for a widget image instance will be | |
| 1625 some XEmacs window. | |
| 1626 | |
| 1627 If you specify an overly general DOMAIN (e.g. a frame when a window was | |
| 1628 wanted), an error is signaled. If you specify an overly specific DOMAIN | |
| 1629 \(e.g. a window when a device was wanted), the corresponding general domain | |
| 1630 is fetched and used instead. For `make-image-instance', it makes no | |
| 1631 difference whether you specify an overly specific domain or the properly | |
| 1632 general domain derived from it. However, it does matter when creating an | |
| 1633 image instance by instantiating a specifier or glyph (e.g. with | |
| 1634 `glyph-image-instance'), because the more specific domain causes spec lookup | |
| 1635 to start there and proceed to more general domains. (It would also matter | |
| 1636 when creating an image instance with an instantiator format of `inherit', | |
| 1637 but we currently disallow this. #### We should fix this.) | |
| 1638 | |
| 1639 If omitted, DOMAIN defaults to the selected window. | |
| 1640 | |
| 444 | 1641 NOERROR controls what happens when the image cannot be generated. |
| 428 | 1642 If nil, an error message is generated. If t, no messages are |
| 1643 generated and this function returns nil. If anything else, a warning | |
| 440 | 1644 message is generated and this function returns nil. |

| 5574 display tables that apply (obtained by calling `specifier-instance' on | |
| 5575 `current-display-table' and any overriding display tables specified in | |
| 5576 currently active faces). The first entry found that matches the | |
| 5577 character determines how the character is displayed. If there is no | |
| 5578 matching entry, the default display method is used. (Non-control | |
| 5579 characters are displayed as themselves and control characters are | |
| 5580 displayed according to the buffer-local variable `ctl-arrow'. Control | |
| 5581 characters are further affected by `control-arrow-glyph' and | |

| 5584 Each instantiator in this specifier and the display-table specifiers | |
| 5585 in faces is a display table or a list of such tables. If a list, each | |

| 5587 character. Each display table is one of | |
| 5588 | |
| 5589 -- a vector, specifying values for characters starting at 0 | |
| 5590 -- a char table, either of type `char' or `generic' | |
| 5591 -- a range table | |

| 5595 -- nil (this entry is ignored and the search continues) | |
| 5596 -- a character (use this character; if it happens to be the same as | |
