/**
*
* w/h is the total window width/height including all its
* decorations (e.g. title bar). cw/ch is the "client", or
* interior width/height. Negative values for w/h/cw/ch are
* treated as "not set". For example: setBounds(x, y, xSet,
* ySet, 800, 600, -1, -1) will make the window 800x600 pixels.
* The client area available for drawing will be smaller, e.g.
* 792x580 - it depends on the window decorations on different
* platforms. setBounds(x, y, xSet, ySet, -1, -1, 800, 600) will
* make the window client size to be 800x600 pixels. The area
* for drawing (FX scene size) will be exactly 800x600, but the
* total window size including decorations will be slightly
* bigger. For undecorated windows w/h and cw/ch are obviously
* the same.
*
* As this is a void function the native code should trigger an
* event to notify the system on actual change
*
