That's fine. 8 bits is the standard size on almost every board today.
[Ob3D] A stencil buffer is used to restrict drawing to only parts of the
screen. In Croquet, you see other worlds through portals. This works by
just rendering a world as if it was the only world on the screen, but
masking off everything that is not visible through the portal. With an 8
bit stencil buffer you could see a portal inside a portal inside a portal
up to a recursive depth of 256. Should be enough for starters.
See TPortal>>enter:depth: if you're interested ;-)
