Update orbiter to make it comply with the google's official material design standard

This is the document of the google's official material design standard.

It looks kinda big. And there's a large gap between the drag border and the top of the exit button.

@dli7319 Thanks David, the user can choose to change the offset value, and scale value to make the button smaller, and closer to the parent panel. The gap between the drag border and the top of the exit button was designed to fit a big orbiter.

Instead of manually closing the gap, maybe we should create a ticket to make the outer panel's boundary adaptive to the inner panel's orbiter size.

Happy New Year and thank you Adam!

The orbiter should be outside of the panel's "draggable region", and please make the orbiter's default position as "top left" and letting the close button aligning with the left edge of the panel, instead of placing to the "top left" corner --- I know it may be different from official guide, but aligning more with our UX design, thanks!
