Subject: remove unused taper0
X-Git-Tag: 2.47.3~29^2~8
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=32a22bd179ecefca514672e5fca32181a5919a63;p=graphviz

remove unused taper0

This function’s only use is in test code and the header declaring its prototype
is not shipped. It is simpler to omit this (and utility function halffunc) from
the libcommon build entirely. Squashes one -Wmissing-prototypes warning.
