Does Cairo support subpixel antialiasing on arbitrary paths?
I'm interested in subpixel antialiasing on 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 codepath?
Behdad Esfahbod says this is not possible. http://lists.cairographics.org/archives/cairo/2015-February/025982.html
