I don't know if this will help, but here goes. Before I started working with SVG 
I had never used vector graphics. It took me a while to figure out how some 
things worked. Here's one of the things I had trouble wrapping my head around, 
lines have a width of 0.

I mean I knew that from math and trig from school, but coming to the realization 
of this fact helped me to understand why SVG behaved the way it did in some 
cases. Lines have to have strokes to be visible and it has been my experience 
that SVG renders stroke-widths of less than 1 as lighter colors so they look 
smaller but the minimum stroke width is still 1 pixel.
