double type for vertex attributes is a 1.0 feature, actually. Albeit prior to
1.1 you couldn't use glVertexPointer and friends... Not to mention buffer
objects...
(Albeit I'd say you really should avoid it usually in any case, it will just
get converted to float somewhere. Unless your data naturally comes as doubles,
so it has to be converted somewhere no matter what.)
