I don't feel too strongly about this, and I would certainly be fine
with the change if e.g. Alexandre preferred it that way, but note that
using NULL here slightly obfuscates the fact that we write the result
to offset 0 in the currently bound buffer object. (I.e., "map_ptr[0]",
compared to "map_ptr[1]" in the line following the changed one)
