heavy internal modifications to introduce the concept of
"module services". This is the first step towards a massive
simplification of the engine's internals, in order to
get rid of various numbers of hacks.
Note that this changes will break source & binary compatibility
for authors of external font drivers.
Maybe 2.1.6 will be called 2.2.0 after all :-)
