Draw calls

Each container has different draw call count

• A VerticalBox or SizeBox or such do have 1 Draw call.
• An overlay uses 2, cause of z Sorting
• A Canvas.. uses 3.. up to 5.. depending on Anchoring, pivot and z sorting

If you nest two Vertical Boxes.. you get 2 Draw calls Nest two Overlays.. you get 4 Draw calls Nest two Canvases.. you get 9-15 Draw Calls.. cause their Draw calls raise exponential
