Scaling issue

[rs9899]

While running the command
pyfractal.GUI().run() from jupyter notebook on a windows machine, the canvas generated is not scaled as per screen size. Pinch too zoom did correct the canvas size later, put initial left side canvas was too big to see the output.

Maybe the canvas can be adjusted as per the window size of the user.

Thanks
