HID multitouch display support in JavaFX

[Michael Paus]

Having proper and consistent Multitouch support on all platforms is 
certainly
an interesting goal, especially if your development is targeting a 
mobile platform. If one
could test the input behavior already on the desktop, this would be an
enormous time saver because the turn-around times 
(edit-compile-build-deploy-debug-curse)
for mobile are currently still extremely high and thus not very 
development-friendly.
I learned from your mail that the situation on Windows seems to be better
than on macOS, which is my current development environment. That gives
me an idea :-)
