Subject: add new test_min_edge_stem_arrow_overlap_simple test
X-Git-Tag: 6.0.2~34^2~2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=aea4357c2bd818b275ca6925bd7e3ab6fa6278cf;p=graphviz

add new test_min_edge_stem_arrow_overlap_simple test

An upcoming commit series will add separate fixes for different parts
of the overlap problems. Having separate test cases for checking
maximum or minimum overlap will make it easier to see that the fixes
have the intended effect.
