I wonder what would be most efficient way to render the GUI elements.

When we're talking about constant-size elements (that can still be moving), the textures' atlas seems to be good.

But what with the resizeable elements?

Let's say the panel (with textured borders)?

Is there any better way than just render 9 rectangles with textures on them (I guess one texture and different textures coordinates for left-top corner, border, middle etc. used in shader)?
