* Read the unit back instead of switching to 0, this avoids messing around with the state manager's
* gl states. The current texture unit should always be a valid one.
*
* To be more specific, this is tricky because we can implicitly be called
* from sampler() in state.c. This means we can't touch anything other than
* whatever happens to be the currently active texture, or we would risk
* marking already applied sampler states dirty again.
*
* TODO: Track the current active texture per GL context instead of using glGet
