[cairo] How can I draw a curve (with cairo_curve_to) on GPU

[Jeong-Joon Yoo]

Dear cairo member,

I heard that most of 2D drawing APIs are not accelerated on GPU.
To check it, I would like to test the performance of cairo_curve_to
when I use a GPU.
Can anybody show me some example of cairo source code or related URL?

Finally, I would like to test the performance of tiger bench (shown in
cairo test suite) when I use a GPU.

Thank you in advance.
