Well i have already worked on display optimization , I used to
- keep a bitmap buffer which represent the whole view scaled on the 
current zoom factor
- rebuild the bitmap from the original image each time user zoom with 
the virtual size
- blit only the displayed view from the bitmap buffer to the view with 
the device coord

How to know when zoom has been performed in the canvasView, can i catch 
an event ?
