Zoom / Canvas Size Changed #73

Hi All,

  I want to create function for zooming using pinch gesture, but there is something strange, every time pinch zoom already changes the canvas size, it's blank all the canvas and rerender.  Is there any option or way to avoid canvas blank when rerender the page using new changed size?
Thanks

Best Regards,
Santo

Whenever the canvas is drawn, it is drawn from scratch, yes, that's how the 
canvas drawing model works.  I think there may be a way of using surface to get 
around that.
