README

        Marlin-renderer

===============

Marlin is an open source (GPL2 + CP) Java2D ``RenderingEngine`` optimized for performance (improved memory usage (~ no GC) and footprint, better multi-threading) and better visual quality based on OpenJDK's Pisces implementation.

It handles shape rendering like ``Graphics2D draw(Shape) / fill(Shape)`` with stroke & dash attributes only but it does it very well !
