Finally I propose to focus on optimizing these 2 algorithms (methods) as it represents 55% of cpu time: - optimize / modify algorithms: integer instead of float ops, reduce number of condition statements (if) to improve branch prediction ...

I have been fancying a port to java of the agg liteweight rasterize ( http://www.antigrain.com/download/index.html) and indeed that code, besides producing high quality antialiased outputs, works with rescaled integers. Might be work having a look
