The Stretchy package (stylized as \stretchylogo) is a package for creating ``stretched'' symbols.
These are symbols which can be arbitrarily stretched in some way, for example the e and t in the Stretchy logo
itself.
Stretchy is a plain-\TeX{} package, but works with \LaTeX{} as well.
Stretchy works with both pdf\TeX{} and Lua\TeX.

\bwarning
    Stretchy only currently supports the Computer Modern Roman 10pt font.
    Further support may or may not be added in the future.

Stretchy works by injecting PDF code directly into the underlying file in order to draw shapes that connect
parts of preexisting glyphs.
For example, take the Stretchy logo:

\centerline{\stretchylogo}

\noindent the e is made from two horizontal halves of the e glyph, connected by two bars drawn using PDF code,
via \macro\pdfliteral s.
The PDF code is injected so that the added graphical elements line up at roughly the correct placement, but
this is done through measurements of the glyph, not by studying its source.
This generally gives good results, but due to the fact that Stretchy mixes PDF path and glyph painting,
PDF consumers do not always produce visually pleasing results at all levels of magnification.
This is unavoidable (when using the method used by Stretchy) unfortunately.
