In [changeset:"0f7d3d5628d0cf598c27ffe69e6fb25e8d05fe5d/git" 0f7d3d5/git]:
{{{#!CommitTicketReference repository="git"
revision="0f7d3d5628d0cf598c27ffe69e6fb25e8d05fe5d"
Clean up and add another special case to lw_dist2d_pt_seg()
When the seg is vertical or horizontal, we construct the
nearest points to avoid getting a difference between
the more-exact distance calculation that doesn't construct
and the naturally constructive process of building
a bbox, which can result in a situation where the
"real distance" between two objects can be less than
the "box distance", which is simply not allowed.
