A new major pixman release 0.20.0 is now available. Highlights of this
release:
* Gradient improvements
- Radial gradients follow the PDF specification [Andrea Canciani]
- Large linear gradients are rendered much more accurately [Andrea]
- Conical gradients now work much better [Søren Sandmann Pedersen]
* Performance improvements
- Faster image scaling [Siarhei Siamashka]
- Faster affine transformations [Søren]
- Improvements to the ARM NEON [Siarhei]
- Improvements to the SSE2 backend [Siarhei, Søren]
Plus a large number of bug and portability fixes, and improvements to
the test suite.
