Subject: [PATCH] tools: Set unit of SVG surface explicitly
Set unit of created surface to CAIRO_SVG_UNIT_PT since current
Cairo defaults to CAIRO_SVG_UNIT_USER which corresponds
to CAIRO_SVG_UNIT_PX (1/96th of inch) although documentation
of cairo_svg_surface_create() says that it requires width
and height in points.
