[Patch] removing trailing whitespace from svg-output

[Arun P. <ape...@lb...>]

Hi

attached is a patch that removes some whitespace from svg-output. It
replaces the function SVG_PathLimit that was used called after each M or
L command to wrap long lines with another functions that either adds the
newline or adds a space and the trailing space is removed from the
commands M and L.

It also removes a few traling whitespaces from the svg-header.

Works for me, but I don't use any extras that seem to be available in
the header.

cheers

Arun
