The most important resource is PLRM.pdf (available on Adobe's website,
though the location changes).

There is a reason this file is commented sparingly: it appears in
every PostScript file produced by LilyPond.

PostScript is a rather idiosyncratic language, so one can't really
replace knowing the language with liberal amounts of commenting.

There is no such things as a "rounded" line, but the corner join style
might be producing circles.

At any rate, this kind of rendition is only used when all of width,
height, and corner diameter are non-zero.  And calling painting
operations "objects" is a somewhat strange view.
