title: object not rotating properly after translate transform in wpf?
body: <p>I have canvas with several cutom controls inherited from panel class, dynamically added to it at runtime with rendertransform=(.5,.5). But when apply translate transform (50,50) and rotate it by 100 degrees, it does not rotate on its place, it rotates in radius of 50, why? 
  Am I doing wrong something ?</p>
