And just to be clear, because the pointers to the callback functions are
being passed to a C API, they *have* to be extern( C ) -- i.e. they have
to have the same calling convention that the C library expects. If the
library functions used the stdcall calling convention rather than cdecl,
then the callbacks would have to be extern( Windows ). So even a wrapper
that allows you to pass D delegates or function pointers would still
have to internally give GLFW a pointer to a function with the proper
calling convention.
