201Rendition bitsets contain information about colour, font, font styles and
202similar information for each screen cell.
203
204The following "macros" deal with changes in rendition sets. You should
205never just create a bitset, you should always modify an existing one,
206as they contain important information required for correct operation of
207rxvt-unicode.

211=item $rend = urxvt::DEFAULT_RSTYLE
212
213Returns the default rendition, as used when the terminal is starting up or
214being reset. Useful as a base to start when creating renditions.

221
222Return the bit that enabled bold, italic, blink, reverse-video and
223underline, respectively. To enable such a style, just logically OR it into
224the bitset.

237specified one.

240
241Return the "custom" value: Every rendition has 5 bits for use by
242extensions. They can be set and changed as you like and are initially
243zero.
