Roadmap

This is an ever-changing list of development priorities for the maintainers of librsvg. Check this often!

Short term

Fix issue #778 about incorrect offsetting for layers with opacity. Solving this should make it easier to fix the root cause of issue #1, where librsvg cannot compute arbitrary regions for filter effects and it only takes the user-specified viewport into account. See Render tree for details on this.
Continue with the revamp of Text layout.
Support CSS custom properties var(), at least the minimal feature set required for OpenType fonts. See CSS Custom Properties — var().
Make fuzzing good and easy - issue #1018. See the discussion in that issue for details of the pending work.
