The Marlin renderer integrated in OpenJDK9 (JEP 265) corresponds to Marlin 0.7.4.
This enhancement for JDK10 brings changes provided by Marlin 0.7.5, already integrated in OpenJFX9, including:
- added the double-precision variant (DMarlinRenderingEngine) for higher accuracy (double vs float)
- MarlinFX backports (Dasher, Stroker changes from OpenPisces)
- Improved MarlinTileGenerator to efficiently handle asymetric tiles (W x H) with almost full / empty fills
- higher precision of the cubic / quadratic curve conversion to line segments (but up to 10% slower); use the following properties to revert to the previous quality settings: -Dsun.java2d.renderer.cubic_dec_d2=2.5 -Dsun.java2d.renderer.cubic_inc_d1=1.0 -Dsun.java2d.renderer.quad_dec_d2=1.0
- syntax / comment corrections

The default RenderingEngine will use the double-precision variant.
