Subject: Patch by kragen@pobox.com: When tracing is turned on, lines shorter
X-Git-Tag: v2.1a1~464
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a659efe5c75711eab0cca8261254994f6ec44103;p=thirdparty%2FPython%2Fcpython.git

Patch by kragen@pobox.com: When tracing is turned on, lines shorter
than a pixel don't get drawn at all. If you're building long curves
made of such lines, this is a bad thing.
