I have been interested in hardware-accelerated SVG and OpenVG for some time but have not yet found any fully-compliant or complete implementation.

There is ShivaVG which covers only a small portion of the standard and appears to have gone stale about 10 years ago.

So, has anyone worked with a better, more modern & complete OpenVG implementation and can point me in the right direction?

Either commercial or FOSS is fine.
