Documentation conceptual index: zoom factor for canvas

[Hannes Hirzel]

The answer to the question:

    How do I control the zoom factor of the display of a sketch?

is not easily found in the documentation.

A solution is to update the conceptual index.

The method index has a reference to a method #scale:

https://www.gnu.org/software/dr-geo/doc/en/Index.html#Index_fn_letter-S

This leads to
https://www.gnu.org/software/dr-geo/doc/en/Smalltalk-sketch.html#index-scale_003a-on-DrGeoCanvas
Method on DrGeoCanvas: scale: anInteger

An example in the documentation which illustrates how the scaling works would also be useful.

Can you post here a code snipped to integrate in the documentation?
As far as I remember, you wrote some.
