Not sure to fully understand the problem. In what ShivaVG would solve a situation better than with Athens? If I understand well, a then working with Cairo uses the hardware acceleration right?
What is it not enough for you need?

First, OpenVG is more complete and i would say thoroughly designed API than Cairo.
Second, i don't want to go�� Athens -> Cairo -> OpenGL
if i can do directly Athens->OpenGL.
Putting extra dependency out of the loop is advantageous, OpenGL is widely supported industry standard, which today you can find even on portable devices, while you cannot say same about Cairo.
��(not mentioning avoiding costs of having multiple layers to get to the hardware).

ShivaVG implements OpenVG API using OpenGL, since OpenVG is vector graphics framework
it can serve as a good source to look how to implement OpenGL backend for Athens.
