Borderless Full Screen

I'm writing a GUI overlay using NEWT (similar behaviour to JWindow, click through, always on top, transparent, etc) but I can't seem to find a way to hide the taskbar icon without making the GLWindow a fullscreen application. I could use JNA to achieve this but I was curious as to wether or not NEWT had the ability to stop the application from showing up in the taskbar.

Here is my code (it's Kotlin):

Hi

There is a request for enhancement about this feature:
https://jogamp.org/bugzilla/show_bug.cgi?id=940

Feel free to help us to implement it. Note that we use GlueGen (JNI) instead of JNA and there is no plan of using Kotlin in JogAmp.
