Hi All,

Here's an update to the proposal on adding absolute delta to 
MouseWheelEvent: it turns out, that Windows, since Windows 8, actually 
/does /offer Mac-like absolute scrolling deltas. That data 
is available for clients of Direct Manipulation API 
in device-independent pixels. We're working on integrating this "modern" 
API (along with the corresponding Mac- and Linux-side improvements).

Thus, 2 of the 3 major OSes already provide absolute scrolling deltas – 
that's an additional argument in favor of the Java's MouseWheelEvent 

Besides, it seems plausible that Linux will also embrace this trend and 
include absolute scrolling deltas in XInput2 and (especially) libinput.

Sincerely, Pavel
