(1) printing_unreadable_object -> printing_unreadable_object_fmt.
(2) printing_unreadable_lcrecord -> printing_unreadable_lisp_object
and fix up so it no longer requires an lcrecord.
These previous changes eliminate most of the remaining places where
the terms `lcrecord' and `lrecord' occurred outside of specialized
code.
(3) Fairly major change: Reduce the number of words in an lcrecord
from 3 to 2. The third word consisted of a uid that duplicated the
lrecord uid, and a single free bit, which was moved into the lrecord
structure. This reduces the size of the `uid' slot from 21 bits to
20 bits. Arguably this isn't enough -- we could easily have more than
1,000,000 or so objects created in a session. The answer is
(a) It doesn't really matter if we overflow the uid field because
it's only used for debugging, to identify an object uniquely
(or pretty much so).
(b) If we cared about it overflowing and wanted to reduce this,
we could make it so that cons, string, float and certain other
frob-block types that never print out the uid simply don't
store a uid in them and don't increment the lrecord_uid_counter.
(4) In conjunction with (3), create new macro NORMAL_LISP_OBJECT_UID()
and use it to abstract out the differences between NEWGC and old-GC
in accessing the `uid' value from a "normal Lisp Object pointer".
(5) In events.c, use zero_nonsized_lisp_object() in place of custom-
written equivalent. In font-mgr.c use external_object_printer()
in place of custom-written equivalents.

| 1551 Image-instance objects encapsulate the way a particular image (pixmap, | |
| 1552 etc.) is displayed on a particular device. In most circumstances, you | |
| 1553 do not need to directly create image instances; use a glyph instead. | |
| 1554 However, it may occasionally be useful to explicitly create image | |
| 1555 instances, if you want more control over the instantiation process. | |
| 1556 | |
| 1557 DATA is an image instantiator, which describes the image; see | |
| 442 | 1558 `make-image-specifier' for a description of the allowed values. |
| 428 | 1559 |
| 1560 DEST-TYPES should be a list of allowed image instance types that can | |
| 1561 be generated. The recognized image instance types are | |
| 1562 | |
| 2959 | 1563 `nothing' |
| 428 | 1564 Nothing is displayed. |
| 2959 | 1565 `text' |
| 428 | 1566 Displayed as text. The foreground and background colors and the |
| 1567 font of the text are specified independent of the pixmap. Typically | |
| 1568 these attributes will come from the face of the surrounding text, | |
| 1569 unless a face is specified for the glyph in which the image appears. | |
| 2959 | 1570 `mono-pixmap' |
| 428 | 1571 Displayed as a mono pixmap (a pixmap with only two colors where the |
| 1572 foreground and background can be specified independent of the pixmap; | |
| 1573 typically the pixmap assumes the foreground and background colors of | |
| 1574 the text around it, unless a face is specified for the glyph in which | |
| 1575 the image appears). | |
| 2959 | 1576 `color-pixmap' |
| 428 | 1577 Displayed as a color pixmap. |
| 2959 | 1578 `pointer' |
| 428 | 1579 Used as the mouse pointer for a window. |
| 2959 | 1580 `subwindow' |
| 428 | 1581 A child window that is treated as an image. This allows (e.g.) |
| 1582 another program to be responsible for drawing into the window. | |
| 2959 | 1583 `widget' |
| 428 | 1584 A child window that contains a window-system widget, e.g. a push |
| 442 | 1585 button, text field, or slider. |
| 1586 | |
| 1587 The DEST-TYPES list is unordered. If multiple destination types are | |
| 1588 possible for a given instantiator, the "most natural" type for the | |
| 1589 instantiator's format is chosen. (For XBM, the most natural types are | |
| 1590 `mono-pixmap', followed by `color-pixmap', followed by `pointer'. For | |
| 1591 the other normal image formats, the most natural types are | |
| 1592 `color-pixmap', followed by `mono-pixmap', followed by `pointer'. For | |
| 1593 the string and formatted-string formats, the most natural types are | |
| 1594 `text', followed by `mono-pixmap' (not currently implemented), | |
| 1595 followed by `color-pixmap' (not currently implemented). For MS | |
| 1596 Windows resources, the most natural type for pointer resources is | |
| 1597 `pointer', and for the others it's `color-pixmap'. The other formats | |
| 1598 can only be instantiated as one type. (If you want to control more | |
| 1599 specifically the order of the types into which an image is | |
| 1600 instantiated, just call `make-image-instance' repeatedly until it | |
| 1601 succeeds, passing less and less preferred destination types each | |
| 1602 time.) | |
| 1603 | |
| 1604 See `make-image-specifier' for a description of the different image | |
| 1605 instantiator formats. | |
| 428 | 1606 |
| 1607 If DEST-TYPES is omitted, all possible types are allowed. | |
| 1608 | |
| 442 | 1609 DOMAIN specifies the domain to which the image instance will be attached. |
| 1610 This domain is termed the \"governing domain\". The type of the governing | |
| 1611 domain depends on the image instantiator format. (Although, more correctly, | |
| 1612 it should probably depend on the image instance type.) For example, pixmap | |
| 1613 image instances are specific to a device, but widget image instances are | |
| 1614 specific to a particular XEmacs window because in order to display such a | |
| 1615 widget when two windows onto the same buffer want to display the widget, | |
| 1616 two separate underlying widgets must be created. (That's because a widget | |
| 1617 is actually a child window-system window, and all window-system windows have | |
| 1618 a unique existence on the screen.) This means that the governing domain for | |
| 1619 a pixmap image instance will be some device (most likely, the only existing | |
| 1620 device), whereas the governing domain for a widget image instance will be | |
| 1621 some XEmacs window. | |
| 1622 | |
| 1623 If you specify an overly general DOMAIN (e.g. a frame when a window was | |
| 1624 wanted), an error is signaled. If you specify an overly specific DOMAIN | |
| 1625 \(e.g. a window when a device was wanted), the corresponding general domain | |
| 1626 is fetched and used instead. For `make-image-instance', it makes no | |
| 1627 difference whether you specify an overly specific domain or the properly | |
| 1628 general domain derived from it. However, it does matter when creating an | |
| 1629 image instance by instantiating a specifier or glyph (e.g. with | |
| 1630 `glyph-image-instance'), because the more specific domain causes spec lookup | |
| 1631 to start there and proceed to more general domains. (It would also matter | |
| 1632 when creating an image instance with an instantiator format of `inherit', | |
| 1633 but we currently disallow this. #### We should fix this.) | |
| 1634 | |
| 1635 If omitted, DOMAIN defaults to the selected window. | |
| 1636 | |
| 444 | 1637 NOERROR controls what happens when the image cannot be generated. |
| 428 | 1638 If nil, an error message is generated. If t, no messages are |
| 1639 generated and this function returns nil. If anything else, a warning | |
| 440 | 1640 message is generated and this function returns nil. |

| 5567 Display tables are used to control how characters are displayed. Each | |
| 5568 time that redisplay processes a character, it is looked up in all the | |
| 5569 display tables that apply (obtained by calling `specifier-instance' on | |
| 5570 `current-display-table' and any overriding display tables specified in | |
| 5571 currently active faces). The first entry found that matches the | |
| 5572 character determines how the character is displayed. If there is no | |
| 5573 matching entry, the default display method is used. (Non-control | |
| 5574 characters are displayed as themselves and control characters are | |
| 5575 displayed according to the buffer-local variable `ctl-arrow'. Control | |
| 5576 characters are further affected by `control-arrow-glyph' and | |
| 5577 `octal-escape-glyph'.) | |
| 5578 | |
| 5579 Each instantiator in this specifier and the display-table specifiers | |
| 5580 in faces is a display table or a list of such tables. If a list, each | |
| 5581 table will be searched in turn for an entry matching a particular | |
| 5582 character. Each display table is one of | |
| 5583 | |
| 5584 -- a vector, specifying values for characters starting at 0 | |
| 5585 -- a char table, either of type `char' or `generic' | |
| 5586 -- a range table | |
| 5587 | |
| 5588 Each entry in a display table should be one of | |
| 5589 | |
| 5590 -- nil (this entry is ignored and the search continues) | |
| 5591 -- a character (use this character; if it happens to be the same as | |
| 5592 the original character, default processing happens, otherwise | |
| 5593 redisplay attempts to display this character directly; | |
| 5594 #### At some point recursive display-table lookup will be | |
| 5595 implemented.) | |
| 5596 -- a string (display each character in the string directly; | |
| 5597 #### At some point recursive display-table lookup will be | |
| 5598 implemented.) | |
| 5599 -- a glyph (display the glyph; | |
| 5600 #### At some point recursive display-table lookup will be | |
| 5601 implemented when a string glyph is being processed.) | |
| 5602 -- a cons of the form (format "STRING") where STRING is a printf-like | |
| 5603 spec used to process the character. #### Unfortunately no | |
| 5604 formatting directives other than %% are implemented. | |
| 5605 -- a vector (each element of the vector is processed recursively; | |
| 5606 in such a case, nil elements in the vector are simply ignored) | |
| 5607 | |

| 5609 be expanded to include other features, such as referencing characters | |
| 5610 in particular fonts and allowing the character search to continue | |
| 5611 all the way up the chain of specifier instantiators. These features | |
