Apologies if this is posted somewhere else (I did search, promise), but does the TomTomTraffic module have to be round?

I should add that I am extremely new to this (about 2 weeks). I initially started with the GoogleMapsTraffic but just could not get my API key to work. TomTom worked first try.

I have had a look in the files that come with TTT but could not see anything that looked like a height/width setting, just the size (radius).

I would prefer a rectangle as I think it looks better, the functionality is fine.
