/**
* Update the fields of a vertex array structure.
* Update the fields of a vertex array object.
* We need to do a few special things for arrays that live in
* vertex buffer objects.
*
* \param array the array to update
* \param dirtyBit which bit to set in ctx->Array.NewState for this array
* \param elementSize size of each array element, in bytes
* \param size components per element (1, 2, 3 or 4)
* \param type datatype of each component (GL_FLOAT, GL_INT, etc)
* \param stride stride between elements, in elements
* \param normalized are integer types converted to floats in [-1, 1]?
* \param ptr the address (or offset inside VBO) of the array data
