#### do as we'll be creating new files taking up space when its impossible for the user
#### to modify the drawing anyway?
#### Possible work arounds:
#### 1) Always modify a 'tmp' drawing file and have the applet return to this page with
#### a particular action 'postDrawingEdit' for example. And at this point check if the
#### tmp file was modified i.e. diff between the 'original' and the 'tmp' if so then do
#### versioning and redirect to 'browse' on the current page.
#### 2) Too tired.. there must be others..ideas ?
