Possible bug with app:apsv_model_offset="10dp"

When set app:apsv_model_offset="10dp" the circles get cut by the edges of the view, the solution is in the line 827 of the ArcProgressStackView.java

Change
final float modelOffset = (mProgressModelSize * i) +
(paintOffset + shadowOffset) - (mProgressModelOffset * i);

With
final float modelOffset = (mProgressModelSize * i) +
(paintOffset + shadowOffset) + (mProgressModelOffset * i);

if you put + (mProgressModelOffset * i); works perfectly

Hope this help
Best Regards
