Add extra room to transform stack; 

Currently the transform stack doesn't take into account the fact that internal functions use
transforms.  Performing error checking for the transform stack in the internal functions is kind of
difficult (right now we just segfault), so it's easier to just reserve a few of the transforms for
internal use.
