'outlinetext' feature

[jemmybutton]

There's outlinetext function in ConTeXt's font loading system, which is sometimes very useful, and which, at the moment, seems to be missing in LuaLaTeX's set of MetaPost tools. In ConTeXt it's a part of font loading system. For this reason I though it might be a feature of luaotfload latex3/luaotfload#271 to make things more similar.
With mplibglyph function #132 luamplib seems to be closer to the implementation of outlinetext than luaotfload and more logical at that.

v2.31 provides a new metapost operator mpliboutlinetext. Please give it a try.

This works absolutely fantastic! Thank you so much! In fact, it seems to work even better than the original outlinetext in some respects. For instance, it seems to respect RtL scripts, which outlinetext had troubles with ( https://tracker.luatex.org/view.php?id=1023 ) and, as of now, as I just tested, still has.

Oh, sorry, the issue can be closed
