don't call Len() when it can't change
...
updateData()'s loops checking gt.Len() turns out to have been costing
significant computation, not least because each call then in turn
called gt.vs.Stride().

Don't duplicate computations in gltriangles.go
...
The computation including a call to Stride() can't be optimized away
safely because the compiler can't tell that Stride() is effectively
constant, but we know it won't change so we can make a slice pointing
at that part of the array.
CPU time for updateData goes from 26.35% to 18.65% in my test case.
