When joining two strokes in paint mode using the auto merge option, the join was very hard if the thickness was too different. This patch adds a smooth to the join in order to get better transition. Also fixed the problem to join existing strokes very far from actual stroke. Some cleanup and rename of old code is included in order to make code more readable.
