200
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.
