I have questions.
Which benchmark are you using?
How does it improve?
Why is it using the single move paths?
Why is cairo_path_extents slower for the case?

[Fujii Hironori]

Oops. I misread and misunderstood.
This is not a speed-up, but a bug fix.
Do you have a test case?

Could you explain here what's wrong exactly. Are we rendering anything incorrectly? does this fix any test? or can we add a new one?

This could be a single line.

r- for comment#4.

Sorry, I should have been clearer. This fixes the new fast/svg/bounding-rect-for-path-with-only-move-command.html test which was added recently, I will add that to the changelog, and fix the formatting issue. Thanks for taking a look.
