Why the metapost not updated the value of text variables that are
generated
inside luacode environment?
In the code below, If I have \startitemize[columns,two] then metapost
draw:
1. \Bolha[size=6cm]{text1}{text2}{text3},
2. and four \Bolha[size=4cm]{text1}{text2}{text3}, but text1, text2 and
text3 is not updated in every call;
Use useMPgraphic instead of uniqueMPgraphic.
uniqueMPgraphic recomputes the graphic only when the dimensions of
figure has changed; otherwise, it reuses the previously drawn graphic.
This behavior was useful for drawing page-backgrounds etc in MkII where
calling metapost was slow.
not only dimensions, also the overlay related colors (and if needed one
can extend the hash used) .. an other advantage (also in mkiv) is that
reuse also makes the pdf file smaller
