You're welcome. No problem at all.

Sure. I usually just let my editor take care of it, but it looks like
the following is close enough for me:

    indent -i4 -bli0

Ah, since it is related, feel free to just leave it.

I looked at the SVG regressions a bit. So far, valgrind found a
missing:

	_cairo_color_init (&stop->color);

just before _cairo_color_set_rgb in cairo_pattern_add_color_stop.

And I noticed that a solid "red" pattern comes through as R=255, G=1,
B=1 instead of R=255, G=0, B=0. Haven't chased it further than that,
but it's also not a reason to hold up the commit.
