Update AFT examples

Added a note to example 3 specifying that it was demonstrating the
"float" property.

Added information about functionality I only just realized existed: the
ability to draw outside of the screen's draw cycle.

 	Because it is not drawing to the screen, an ActorFrameTexture's postion, rotation, and zoom have no affect. Diffuse and 
 	glow are applied to the children of an ActorFrameTexture the same way they are applied to the children of an ActorFrame.
+	Additionally, an ActorFrameTexture can draw to it's texture at any time, by calling the Actor method Draw. For all other
+	Actor classes, the Draw method will have no effect if called outside of the Screen's draw cycle.
 	
 	ActorFrameTextures draw only actors or parts of actors that are located within the range x = 0 to x = <width> and y = 0
 	to y = <height>. If an actor is sitting at x = 0 inside the ActorFrameTexture, only the right half of the Actor will draw.
