[Dgame] Is there Multiple Window support?

[Jack via Digitalmars-d-learn]

Hello, so I've been experimenting with the framework and I tried 
to implement a game that has more than two windows.

The first window is the main game and the second window is a 
smaller one with the various commands you can select.

So I tried to render sprites onto the first window and the second 
window, and failed.

------------------

window_1.clear();
window_2.clear();
window_1.draw(sprite_1);
window_2.draw(sprite_2);
window_1.display();
window_2.display();
-------------------

So far, when two windows are called to clear, draw and display, 
it didn't render anything. There was no error message, but once I 
commented out the window_2 calls, it rendered the first window 
without flaw.

So are multiple windows supported here?
