[XeTeX] Stroking a TeX rule in XeTeX

[Philip Taylor (RHUoL)]

The following code applies a 3 pt blue stroke to red-filled glyphs, but
has the undesirable side-effect of changing the colour of TeX rules to
the stroke colour.  Is it possible, does anyone know, to control the
stroke and fill colour of TeX rules (a) independently, and (b)
orthogonally to that of TeX glyphs ?

Yes, both in pdftex in xetex the stroke colour and fill colour are
independent. You can even change the rendering mode of text and print glyph
outlines in one colour with a specified line width and fill them with
another colour. It is shown in my article:
Zdeněk Wagner: Tisk obrysu písma v PDF
which is available here: http://bulletin.cstug.cz/bul2013-1.shtml
It is written in Czech but I hope you can find the code.
