The context as such is only used for the commands. Tools are activated
through commands as shown in the simple_tool.py example so getting hold
of the context shouldn't be a problem.

In the tool object itself you can use self.view if you need to access
the map window the tool is operating on. That self.view is the same as
context.mainwindow.canvas.
