Make #'find-function behave better with dumped functions, installed XEmacs
2010-01-30 Aidan Kehoe <kehoea@parhasard.net>
* loadup.el:
If any filename in load-history starts with the value of
source-lisp, delete that part of the string, so that
#'find-function works better with dumped functions in an installed
XEmacs (it will look in lisp-directory instead, where it will
probably succeed).

| 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 | |

| 1554 Image-instance objects encapsulate the way a particular image (pixmap, | |
| 1555 etc.) is displayed on a particular device. In most circumstances, you | |
| 1556 do not need to directly create image instances; use a glyph instead. | |
| 1557 However, it may occasionally be useful to explicitly create image | |
| 1558 instances, if you want more control over the instantiation process. | |
| 1559 | |
| 1560 DATA is an image instantiator, which describes the image; see | |
| 442 | 1561 `make-image-specifier' for a description of the allowed values. |
| 428 | 1562 |
| 1563 DEST-TYPES should be a list of allowed image instance types that can | |
| 1564 be generated. The recognized image instance types are | |
| 1565 | |
| 2959 | 1566 `nothing' |
| 428 | 1567 Nothing is displayed. |
| 2959 | 1568 `text' |
| 428 | 1569 Displayed as text. The foreground and background colors and the |
| 1570 font of the text are specified independent of the pixmap. Typically | |
| 1571 these attributes will come from the face of the surrounding text, | |
| 1572 unless a face is specified for the glyph in which the image appears. | |
| 2959 | 1573 `mono-pixmap' |
| 428 | 1574 Displayed as a mono pixmap (a pixmap with only two colors where the |
| 1575 foreground and background can be specified independent of the pixmap; | |
| 1576 typically the pixmap assumes the foreground and background colors of | |
| 1577 the text around it, unless a face is specified for the glyph in which | |
| 1578 the image appears). | |
| 2959 | 1579 `color-pixmap' |
| 428 | 1580 Displayed as a color pixmap. |
| 2959 | 1581 `pointer' |
| 428 | 1582 Used as the mouse pointer for a window. |
| 2959 | 1583 `subwindow' |
| 428 | 1584 A child window that is treated as an image. This allows (e.g.) |
| 1585 another program to be responsible for drawing into the window. | |
| 2959 | 1586 `widget' |
| 428 | 1587 A child window that contains a window-system widget, e.g. a push |
| 442 | 1588 button, text field, or slider. |
| 1589 | |
| 1590 The DEST-TYPES list is unordered. If multiple destination types are | |
| 1591 possible for a given instantiator, the "most natural" type for the | |
| 1592 instantiator's format is chosen. (For XBM, the most natural types are | |
| 1593 `mono-pixmap', followed by `color-pixmap', followed by `pointer'. For | |
| 1594 the other normal image formats, the most natural types are | |
| 1595 `color-pixmap', followed by `mono-pixmap', followed by `pointer'. For | |
| 1596 the string and formatted-string formats, the most natural types are | |
| 1597 `text', followed by `mono-pixmap' (not currently implemented), | |
| 1598 followed by `color-pixmap' (not currently implemented). For MS | |
| 1599 Windows resources, the most natural type for pointer resources is | |
| 1600 `pointer', and for the others it's `color-pixmap'. The other formats | |
| 1601 can only be instantiated as one type. (If you want to control more | |
| 1602 specifically the order of the types into which an image is | |
| 1603 instantiated, just call `make-image-instance' repeatedly until it | |
| 1604 succeeds, passing less and less preferred destination types each | |
| 1605 time.) | |
| 1606 | |
| 1607 See `make-image-specifier' for a description of the different image | |
| 1608 instantiator formats. | |
| 428 | 1609 |
| 1610 If DEST-TYPES is omitted, all possible types are allowed. | |
| 1611 | |
| 442 | 1612 DOMAIN specifies the domain to which the image instance will be attached. |
| 1613 This domain is termed the \"governing domain\". The type of the governing | |
| 1614 domain depends on the image instantiator format. (Although, more correctly, | |
| 1615 it should probably depend on the image instance type.) For example, pixmap | |
| 1616 image instances are specific to a device, but widget image instances are | |
| 1617 specific to a particular XEmacs window because in order to display such a | |
| 1618 widget when two windows onto the same buffer want to display the widget, | |
| 1619 two separate underlying widgets must be created. (That's because a widget | |
| 1620 is actually a child window-system window, and all window-system windows have | |
| 1621 a unique existence on the screen.) This means that the governing domain for | |
| 1622 a pixmap image instance will be some device (most likely, the only existing | |
| 1623 device), whereas the governing domain for a widget image instance will be | |
| 1624 some XEmacs window. | |
| 1625 | |
| 1626 If you specify an overly general DOMAIN (e.g. a frame when a window was | |
| 1627 wanted), an error is signaled. If you specify an overly specific DOMAIN | |
| 1628 \(e.g. a window when a device was wanted), the corresponding general domain | |
| 1629 is fetched and used instead. For `make-image-instance', it makes no | |
| 1630 difference whether you specify an overly specific domain or the properly | |
| 1631 general domain derived from it. However, it does matter when creating an | |
| 1632 image instance by instantiating a specifier or glyph (e.g. with | |
| 1633 `glyph-image-instance'), because the more specific domain causes spec lookup | |
| 1634 to start there and proceed to more general domains. (It would also matter | |
| 1635 when creating an image instance with an instantiator format of `inherit', | |
| 1636 but we currently disallow this. #### We should fix this.) | |
| 1637 | |
| 1638 If omitted, DOMAIN defaults to the selected window. | |
| 1639 | |
| 444 | 1640 NOERROR controls what happens when the image cannot be generated. |
| 428 | 1641 If nil, an error message is generated. If t, no messages are |
| 1642 generated and this function returns nil. If anything else, a warning | |
| 440 | 1643 message is generated and this function returns nil. |

| 5523 display tables that apply (obtained by calling `specifier-instance' on | |
| 5524 `current-display-table' and any overriding display tables specified in | |
| 5525 currently active faces). The first entry found that matches the | |
| 5526 character determines how the character is displayed. If there is no | |
| 5527 matching entry, the default display method is used. (Non-control | |
| 5528 characters are displayed as themselves and control characters are | |
| 5529 displayed according to the buffer-local variable `ctl-arrow'. Control | |
| 5530 characters are further affected by `control-arrow-glyph' and | |
| 5531 `octal-escape-glyph'.) | |
| 5532 | |
| 5533 Each instantiator in this specifier and the display-table specifiers | |
| 5534 in faces is a display table or a list of such tables. If a list, each | |
| 5535 table will be searched in turn for an entry matching a particular | |
| 5536 character. Each display table is one of | |
| 5537 | |
| 5538 -- a vector, specifying values for characters starting at 0 | |
| 5539 -- a char table, either of type `char' or `generic' | |
| 5540 -- a range table | |
| 5541 | |
| 5542 Each entry in a display table should be one of | |
| 5543 | |
| 5544 -- nil (this entry is ignored and the search continues) | |
| 5545 -- a character (use this character; if it happens to be the same as | |
| 5546 the original character, default processing happens, otherwise | |
| 5547 redisplay attempts to display this character directly; | |
| 5548 #### At some point recursive display-table lookup will be | |
| 5549 implemented.) | |
| 5550 -- a string (display each character in the string directly; | |
| 5551 #### At some point recursive display-table lookup will be | |
| 5552 implemented.) | |
| 5553 -- a glyph (display the glyph; | |
| 5554 #### At some point recursive display-table lookup will be | |
| 5555 implemented when a string glyph is being processed.) | |
| 5556 -- a cons of the form (format "STRING") where STRING is a printf-like | |
| 5557 spec used to process the character. #### Unfortunately no | |
| 5558 formatting directives other than %% are implemented. | |
| 5559 -- a vector (each element of the vector is processed recursively; | |
| 5560 in such a case, nil elements in the vector are simply ignored) | |
| 5561 | |
| 5562 #### At some point in the near future, display tables are likely to | |
| 5563 be expanded to include other features, such as referencing characters | |
| 5564 in particular fonts and allowing the character search to continue | |
| 5565 all the way up the chain of specifier instantiators. These features | |
| 5566 are necessary to properly display Unicode characters. | |
