[Bf-committers] poll: uv/col mirror might not work for bmesh ngons

[Wael EL ORAIBY]

Indeed, the problem with the current code is that it only switch the
uvs of parallel edges in a quad, so this is what they call axis, of
course, this is possible for an ngon with even vertex count, but still
require to select a base edge for the operation. In the case of odd
vertex count we need to select a vertex. Too much work for little use
imho (more work on UI than on the code itself).

I wonder if this is not a very old zombie code from the early versions
of blenders
