After converting SVG Full (using Illustrator) and trying the resulting SVG 
Tiny on my mobile phone it looked pretty ok.
The only remark is that the navigation keys on the left of the map were not 
functional (which is a feature of minor importance for mobile phones 
according to my opinion)
However, I totally agree that we should verify the resulting SVG Tiny more 
thoroughly.
So if you have any Tiny SVGs that you could send me for testing, please do 
so. I will be able to inform you on anything you need.
