Keep our byte-writing within bounds. 

Now that we're writing both 16-bit and 32-bit integers, it's starting to
matter a little more how we slam even scalars into memory. This is maybe
not the fastest way to accomplish this, and I'm not crazy about the way
GLType works in general, but it does have the virtues of clarity and
expediency.
