[cairo] Subpixel antialiasing for arbitrary paths

[litherum]

Hello,

I'm interested in subpixel antialiasing of text, but the version of Cairo that I am using is compiled without support for any underlying text rendering engine (such as Freetype). Therefore, I'm left with the User Fonts backend, which seems to use Cairo's native path rendering APIs to render the glyph contours. Is it possible to achieve LCD subpixel filtering using this code path?

Thanks,
