Subject: svgwrite_diagram: return "something" from draw_centered_text()
X-Git-Url: https://git.ao2.it/flexagon-toolkit.git/commitdiff_plain/1cd1b488690ff3007df258adbfb198f5bdedfb80?ds=inline

svgwrite_diagram: return "something" from draw_centered_text()

Add a quick and dirty way to advance text when calling
draw_centered_text() just for consistency with the cairo backend.

The return value is just a rough estimate, it does not consider the
particular font in use.
