Cursor should reflect current drawing tool

[GoogleCodeExporter]

Provide a brief description of the requested feature:

To give the user a better understanding of the size of the affected area under 
the cursor by the current drawing tool, the mouse cursor should change into 
something that reflects the current drawing tool, and possibly gives hints 
about the area size to be affected.
