Update the fields of a vertex array object. We need to do a few special things for arrays that live in vertex buffer objects.

Parameters:

array	the array to update
dirtyBit	which bit to set in ctx->Array.NewState for this array
elementSize	size of each array element, in bytes
size	components per element (1, 2, 3 or 4)
type	datatype of each component (GL_FLOAT, GL_INT, etc)
stride	stride between elements, in elements
normalized	are integer types converted to floats in [-1, 1]?
ptr	the address (or offset inside VBO) of the array data
