Paint supports translate, rotate, scale functions for transformation The origin of these transformation is center of the paint, thus you have to consider the center-aligned vertices if you'd like to use these transformation functions. This policy has been considered for scene transformation. Change-Id: I78b63d7965faec0ec5b9a98a7776993744534b54
