(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.

/* Overview of functions provided here:
 *
 * AllocFgGC()
 *	Given a foreground pixel & a font, return an appropriate GC
 *
 * AllocBackgroundGC()
 *	Given a widget, return a GC for painting the background color
 *
 * AllocShadeGC()
 *	Given foreground, background, a contrast value & be_nice_to_colormap
 *	flag, return a GC suitable for rendering in an intermediate color,
 *	as determined by contrast.  May return a dither pattern or a
 *	solid color, as appropriate.
 *
 *	Contrast 0 = background color, 100 = foreground color.  It is legal
 *	for contrast to be more than 100 or less than 0.
 *
 * AllocGreyGC()
 *	Given widget, foreground, font, contrast & be_nice_to_colormap,
 *	return a shade GC (see above) based on foreground and widget
 *	background.
 *
 * AllocTopShadowGC()
 *	Given widget, contrast & be_nice_to_colormap, return a GC suitable
 *	for rendering the top shadow.
 *
 *	Contrast 0 = use background pixel.  Contrast > 0 = use brighter
 *	colors.
 *
 * AllocBotShadowGC()
 *	Given widget, contrast & be_nice_to_colormap, return a GC suitable
 *	for rendering the bottom shadow.
 *
 *	Contrast 0 = use background pixel.  Contrast > 0 = use darker
 *	colors.
 *
 * AllocArmShadowGC()
 *	Given widget, contrast & be_nice_to_colormap, return a GC suitable
 *	for rendering the "armed" shadow.
 *
 *	Contrast 0 = use background pixel.  Contrast > 0 = use darker
 *	colors.
 *
 * AllocShadowPixel()
 *	Given a widget & scale factor, allocate & return a color darker
 *	or lighter than the background pixel, as determined by scale.
 *
 *	Scale 100 = use background pixel.  Scale > 100 = brighter color,
 *	Scale < 100 = darker color.
 *
 * AllocGreyPixel()
 *	Given two pixel values and scale factor, allocate & return a
 *	pixel value between them, according to scale.
 *
 *	Scale == 0:	background color
 *	Scale == 100:	foreground color
 *	0<Scale<100:	intermediate color
 *	Scale > 100:	more foreground
 *	Scale < 0:	more background
 *
 *
 * AllocGreyPixelC()
 *	Given two color values and scale factor, allocate & return a
 *	pixel value between them, according to scale.
 *
 *	Scale == 0:	background color
 *	Scale == 100:	foreground color
 *	0<Scale<100:	intermediate color
 *	Scale > 100:	more foreground
 *	Scale < 0:	more background
 *
 * Draw3dBox()
 *	Given box dimensions, shadow width, top shadow GC & bottom shadow GC,
 *	draw a 3-d box.
