Blender now supports the 10.7+ "Full screen" mode, which pushes a window to a permanent
other "screen", with animated zoom and sliding.
Available via the icon in window header (right), Apple+F, or "Window" menu in top.
Works much nicer than Blender's own "full screen" option.
Todo: the zoom effect is still draws a bit ugly, because Blender doesn't have "live resize"
yet.
