I would investigate these backends before deciding to go with OpenGL, but still you might find OpenGL a good choice.

<br>
I have used an older version of Cairo with a Windows Surface
backend using the pre-compiled libraries from the Gtk for Windows
project in a couple of internal projects using Borland C++
Developer Studio 2006. This was a few years back but it worked
fine.<br>

I can't comment on using an OpenGL backend with Cairo because I have
never tried it. If you need it to be OpenGL enabled, I think
someone else may have better inputs.<br>

"working under Linux, Mac and Windows"... well, the Cairo code may
work but you'll still have to either use something cross-platform
for the platform-specific surfaces, etc. or will need some platform
specific code there anyway.<br>

As a library alone, it would... not sure about the OpenGL part.<br>

Are you using XE3? Even XE3 will only give you Mac OS and Windows,
not Linux. I have not tried using Cairo under Firemonkey but now
there's a thought! You would still need a Mac to compile the MacOS
executable.<br>
<br>
Let me know how it turns out... this is something I'm also keen to
see :)<br>
