It's hard to judge, but I'm quite sure inlining is only a small and
minor optimisation available.
GEOS and GGL follow completely different programming paradigms.
GGL is strongly based on static polymorphism resolved and calculated in
compile-time. This increases changes that compilers will apply finest
possible optimisations.
