[Mesa-dev] [PATCH v2] swr: [rasterizer core] Remove dead code Clipper::ClipScalar()

[Bruce Cherniak]

v2: includes bugzilla reference, same code change


Clipper::ClipScalar() is dead code and should be removed.  It is causing
an error with gcc-7 because it references a now defunct member.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=99633
CC: "13.0 17.0" <mesa-stable at lists.freedesktop.org>
