ThorVG patch releases are prone to regressions as they tend to backport features, so I'm a bit wary of updating so late in the cycle. On the other hand there's a few bug fixes here, notably a buffer overflow one that might be considered security-relevant, so we should probably update.

Let's try it out and keep an eye out for regressions in beta4.
