It would be nice interface to have IFF FreeType did not have the
renderer module interface.

You have to implement (and maintain) hooks instead of maintaining
renderer modules. You are asking secondary libraries to implement
hooks instead of the renderer module. There is nothing absolutely
nothing easier, or more logical, or simpler. It buys you absolutely
nothing!!! They are just an extra unnecessary layer. I don't buy the
arguments about maintaining cost: you now have the whole new interface
to look after.

Given that hooks do not exist and have to be implemented, my question
remains. Why hooks are better than modules? Werner, why?

I would be more happy with a single module for a single library (just
make a choice already!) without any of these hooks. Then we can decide
later once other libraries want to be supported.
