GDS renderer: changed criterion for rounding paths#973

Method QGDSRenderer._qgeometry_to_gds() checks several conditions to decide whether a shapely.geometry.LineString is drawn with rounded or sharp corners. One of them takes into account that if the fillet radius gets too small relative to the width of the line, the rounding cannot be applied correctly anymore, hence drawing the line with sharp corners. Before this commit, this was implemented via the criterion `qgeometry_element.fillet < qgeometry_element.width`; however, this criterion is too strict because corners can well be rounded also if 0.5*width < fillet radius < width. Therefore, this commit changes this criterion to `qgeometry_element.fillet < 0.5 * qgeometry_element.width`.
