* provide new TeX macros to reduce typing toil. \mpfig ... \endmpfig is roughly the abbreviation of \begin{mplibcode}[@mpfig] beginfig(0) token list declared by \everymplib[@mpfig] ... token list declared by \everyendmplib[@mpfig] endfig; \end{mplibcode} \mpfig* ... \endmpfig is roughly the abbreviation of \begin{mplibcode}[@mpfig] ... \end{mplibcode} These macros are protected and unexpandable. In these macros \mpliblegacybehavior{false} is forcibly declared. As both share the same instance name, MetaPost codes are inherited among them. The instance name (default: @mpfig) can be changed by redefining `\mpfiginstancename'. * instance names are allowed in plain TeX as well. The syntax is: \mplibcode[name] ... \endmplibcode \everymplib[name]{ ... } \everyendmplib[name]{ ... } These macros are now protected and unexpandable. * provide new MetaPost operators `mplibtexcolor' and `mplibrgbtexcolor' which convert TeX color expressions to MetaPost color expressions. The latter one forces rgb model results (#112). For instance, mplibtexcolor "olive" % => (0, 0, 1, 0.5) mplibrgbtexcolor "olive" % => (0.5, 0.5, 0) As spot colors are always forced to cmyk or rgb model, it is not recommended to use these operators for them. * write down MetaPost messages into the log file
