+ − 276 In this case, the function is really equivalent to

+ − 290 In general, it is OK to pass an instance object (e.g. as returned
+ − 291 by `face-property-instance') as an instantiator in place of
+ − 292 an actual instantiator. In such a case, the instantiator used
+ − 293 to create that instance object will be used (for example, if
+ − 294 you set a font-instance object as the value of the 'font
+ − 295 property, then the font name used to create that object will

+ − 299
+ − 300 If PROPERTY is not a built-in property, then this function will
+ − 301 simply set its value if LOCALE is nil. However, if LOCALE is
+ − 302 given, then this function will attempt to add VALUE as the
+ − 303 instantiator for the given LOCALE, using `add-spec-to-specifier'.

+ − 1123
+ − 1124 The actual behavior of this function is somewhat messy, in an attempt to

+ − 1128 \"intuitive\" results gets messy, particularly with a system as complicated
+ − 1129 as specifiers, whose complexity results from an attempt to work well in
+ − 1130 many different circumstances.)
+ − 1131
+ − 1132 The meaning of LOCALE is the same as for `specifier-spec-list', i.e.:
+ − 1133
+ − 1134 -- If LOCALE is nil, omitted, or `all', this will attempt to \"frob\" all
+ − 1135 font specifications for FACE to make them appear bold (i.e. the

+ − 1137 font names have been changed to the closest bold font).
+ − 1138
+ − 1139 -- If LOCALE is a locale type \(`buffer', `window', etc.), this frobs all
+ − 1140 font specifications for locales of that type.
+ − 1141
+ − 1142 -- If LOCALE is a particular locale, this frobs all font specifications for
+ − 1143 that locale.
428
+ − 1144
872
+ − 1145 If TAGS is given, this only processes instantiators whose tag set includes
+ − 1146 all tags mentioned in TAGS. In addition, if EXACT-P is non-nil, only
+ − 1147 instantiators whose tag set exactly matches TAGS are processed; otherwise,
+ − 1148 additional tags may be present in the instantiator's tag set.
+ − 1149
+ − 1150 This function proceeeds in three stages.
+ − 1151
+ − 1152 STAGE 1: Frob the settings that are already present.
+ − 1153 STAGE 2: (if called for) Ensure that *some* setting exists in the locale
+ − 1154 that was given, finding it in various ways and frobbing it as in
+ − 1155 stage 1. This ensures that there is an actual setting for
+ − 1156 the locale, so you will get the expected buffer-local/frame-local
+ − 1157 behavior -- changes to the global value, to other locales, won't
+ − 1158 affect this locale, (b) the face will actually look bold in
+ − 1159 the locale.
1137
+ − 1160 STAGE 3: (if called for)
872
+ − 1161
+ − 1162 The way the frobbing works depends on the device type -- first on whether
+ − 1163 or not it's TTY, and second, if it's a window-system device type, on which
+ − 1164 particular window-system device type. For locales with a specific device
+ − 1165 type, we do the frobbing in the context of that device type -- this means
+ − 1166 that for TTY device types we set the highlight flag, and for window-system
+ − 1167 device types we modify the font spec according to the rules for font specs
+ − 1168 of that device type. For global locales, we may process both the highlight
+ − 1169 flag and the font specs (depending on the device types compiled into this
+ − 1170 XEmacs). When processing font specs, we check the tag set associated with
+ − 1171 each font spec to see if it's specific to a particular device type; if so,
+ − 1172 we frob it in the context of that type, else we use the type of the current
+ − 1173 device. (A hack, but works well in practice -- and if a new device is
+ − 1174 created, we will automatically frob all the standard fonts to make sure
+ − 1175 they display OK on that device.)
+ − 1176
+ − 1177 If LOCALE is not a locale type, and both TAGS and EXACT-P are omitted, we
+ − 1178 do further frobbing in an attempt to give more intuitive behavior.
428
+ − 1179
872
+ − 1180 First, if there are no specifications in LOCALE (if LOCALE is `all', we act
+ − 1181 as if it were `global' for this step), we do our utmost to put a
+ − 1182 specification there; otherwise, this function will have no effect. For
+ − 1183 device, frame, or window locales, the face's font is instantiated using the
+ − 1184 locale as a domain, and the resulting font is frobbed and added back as a
+ − 1185 specification for this locale. If LOCALE is `global', we retrieve the
+ − 1186 fallback specs and frob them. If LOCALE is a buffer, things get tricky
+ − 1187 since you can't instantiate a specifier in a buffer domain \(the buffer can
+ − 1188 appear in multiple places, or in different places over time, so this
+ − 1189 operation is not well-defined). We used to signal an error in this case,
+ − 1190 but now we instead try to do something logical so that we work somewhat
+ − 1191 similarly to buffer-local variables. Specifically, we use
+ − 1192 `get-buffer-window' to find a window viewing the buffer, and if there is
+ − 1193 one, use this as a domain to instantiate the font, and frob the resulting
+ − 1194 value. Otherwise, we use the selected window for the same purpose.
+ − 1195
+ − 1196 Finally, if the frobbing didn't actually make the font look any different
+ − 1197 in whatever domain we instantiated the font in (this happens, for example,
+ − 1198 if your font specification is already bold or has no bold equivalent; note
+ − 1199 that in this step, we use the selected device in place of `global' or `all'
+ − 1200 -- another hack, but works well in practice since there's usually only one
+ − 1201 device), and the font currently looks like the font of the `default' face,
+ − 1202 it is set to inherit from the `bold' face.
+ − 1203
+ − 1204 NOTE: For the other functions defined below, the identity of these two
+ − 1205 standard faces mentioned in the previous paragraph, and the TTY properties
+ − 1206 that are modified, may be different, and whether the TTY property or
+ − 1207 properties are set or unset may be different. For example, for
+ − 1208 `make-face-unitalic', the last sentence in the previous paragraph would
+ − 1209 read \"... and the font currently looks like the font of the `italic' face,
+ − 1210 it is set to inherit from the `default' face.\", and the second sentence in
