Some browsers may decide that one Coordinate -> one VBO. Sometimes<br>
this is good (reuse VBO), sometimes bad (if the VBO is actually really<br>
huge).<br>
<br>
And it means that browsers have to do extra work to calculate optimal<br>
(tighter) bounding volumes. A browser that calculates bounding volume<br>
of Shape based on Coordinate contents (not a subset of Coordinate that<br>
is actually used by indexes) will have large bounding box for all<br>
shapes. This applies to CGE/view3dscene (through there's a flag now to<br>
activate slower bbox calculation that looks at indexes, but I heavily<br>
discourage from relying on it -- it is slower).<br>
