commit 37ed508022e0be8b793caa4748cfee634c1c8a9c
Author: Tomaž Vajngerl <tomaz.vajng...@collabora.co.uk>

tdf#99130 use subdivision on B2DPolygon, angle based subdivision
Remove the subdivider we used until now as there is a better
way to subdivide a polygon with getDefaultAdaptiveSubdivision,
which in additiona also caches the result. The subdivider used in
getDefaultAdaptiveSubdivision was a limited count based subdivider
so this exchanges that with an angle based one which gives much
better results.
