              There is a funny corner case here where the clip isn't being set before a draw command is called. Added a check for the null clips and will paint the shape regardless of intersection. Also update the image drawing command to fire an page painter event to help insure the page is repainted for a long running image proxy.

              Check in a fix on the trunk and 5.0.1 branch.
