The code for generating round line joins is optimized with a shortcut for the inner, normally invisible joins. For certain joins of a tightly turning bezier, this optimization would lead to visible painting error. Fix by avoiding the optimization if the next control point is so close as to allow such tight turns. As a driveby, make the angle > 90 test cheaper, since absolute precision is not required in the optimization choice.
