Hi Sandro,

I once was asked to define a mapcanvas with a certain size, and tried it
in python, see:

https://github.com/rduivenvoorde/simplesvg/blob/master/src/simplesvg/mapsizer/MapSizerDialog.py#L93

the hard part (I think) is that the exact size of the mapcanvas was
defined relative to other (parent) widgets, and for example depending on
the OS....

would be cool though to be able to just SET it, given that is the most
important widget in QGIS...

Regards,

Richard
