Hello Sergey,

We’ve resumed our work on smooth scrolling. However, this time we started from other end - we’ve implemented support of touch screen devices on Linux and Windows. I think we can extend it on precise scrolling deltas for high precision mouse devices. Currently we have only private API in our JBR but we’re going to discuss it on OpenJDK alias a bit later. This work is driven by Denis Konoplev. He’ll provide some more technical info soon.

Best Regards,
