This backend should work on any platform where there is a OpenVG
implementation conforming to the specification. For instance ShivaVG
does work on win32.

It isn't official in any other way than that the code is publicly
available. It isn't part of the main cairo repository yet and it
hasn't even gone through testing on actual OpenVG hardware I suspect
that this is something that probably is mainly interesting for mobile
devices, and perhaps through libraries like ShivaVG to achieve
rendering directly to GPU side textures using OpenGL.
Do note however that some backends might be better than others since
this backend doesn't make use of a core OpenVG feature has, persistent
handles for object (amongst them paths). Depending on the
implementation this might make a small or large impact on performance.
