Play and Play Root icons

[blueyeti]

rebounding on the new icons of the V2.0.0a10, here is a proposal for one the play icon:

Thinking to new users, this icon could be for the action of playing the active window (with the tooltip "play window"): the window is represented by the rectangle. The regular play button could be for playing the global scenario.

In my opinion "play" and "play window" could be more clear for new users than "play root" and "play" (for playing the window)

I agree with the names, that's a good idea ! The icon also goes in the right direction, IMHO, but it's not very clear yet: it's not completely obvious the rectangle represents the window - maybe something more rectangle (like less height, so it's horizontally longer ?) and maybe with a little header or something ?

I've a preference to a "light" icon with simple geometry, to keep the play bar simple. The tooltip could help the beginners.
