CTAN update: luamplib

Dohyun Kim submitted an update to the luamplib package. Version: 2.28.0 2024-04-12 License: gpl2 Summary description: Use LuaTeX’s built-in MetaPost interpreter Announcement text:

---

* provide a new metapost operator 'mplibgraphictext', which is similar to ConTeXt's 'graphictext'. But the syntax is not the same: mplibgraphictext "Text" fakebold 2 scale 3 fillcolor red drawcolor blue where 'fakebold' and 'scale' are fontspec's font options. 'fakebold', 'scale', 'drawcolor' and 'fillcolor' are optional and default values are '2', '1', "black" and "white" respectively. When color expressions are given as string, they are regarded as xcolor's or l3color's expressions. The operator generates a metapost picture, which can be drawn or assigned to a variable. For compatibilty with 'graphictext', 'withdrawcolor' and 'withfillcolor' are synonyms of 'drawcolor' and 'fillcolor'. Because the implementation is quite different from the \ConTeXt's, there are some limitations such that we can't apply shading (gradient colors) to the text. * support metafun's new shading method. Color expressions given as string are regarded as xcolor's or l3color's expressions. Spot colors defined by the color commands of l3color package are also acceptable (currently '\DocumentMetadata{ }' is needed for spot colors). * fix the y-position of text figures, which means the result of 'infont' operator, not of the 'textext' operator.
