Stylesheets are a bit confusing but it seems that pixels in
stylesheets actually represent rendered pixels. Even if I'm wrong,
global transformation can be defined for svg file so 1 unit = 1
rendered pixel.

>From a quick look it seems its partly implemented. Osmarender will get
svg files from directory and include all their symbols in generated
file. or/p just include the whole svg file.
