render_svg.c patch

[Mike Sowka <mike sowka com>]

Hello,
I've recently started using xml-docbook/svg for documenting my 4th year
project... I managed to find some bugs in render_svg.c code. The bug
occurs during rendering of arcs. It seems that the case of angles lying
across 0degree boundary was not handled and the large-arc-flag was not
being calculated properly... I've never sent a patch before...  here it
is. For some reason my svgs are still not getting rendered properly...
but at least the large-arc-flag is fixed....
Mike
