Description
OF 0.11 win10
if we resample a polyline to the same amount of vertices for getting another spacing, eg:
polyline = polyline.getResampledByCount(polyline.size()); // OF bug jumps! += 1
the result has a variable length +1, unless we put ceilf in the equation like:
assert(polyline.size() >= 2);
polyline = polyline.getResampledBySpacing(
ceilf(polyline.getPerimeter()) / (polyline.size() - 1)
);
this needs to be fixed in getResampledByCount()

Research direction
Start with ofPolyline::getResampledByCount() and the related getResampledBySpacing() behavior described in the issue. Reproduce the Windows 10 example with a target count equal to the current vertex count, then verify that the result has exactly the requested number of vertices without changing the intended spacing.
