package.

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.
