About the DLL problem (I was already flamed to death in past for this
subject).
DLLs are binary modules which contain code loadable and callable at runtime.
Windows has DLLs. Linux, BSD, Solaris etc.etc. have shared libraries (look
into /usr/lib for all those .so files...). VMS has shared libraries. I
presume that Mac's have a similar mechanism, OSX being a Mach kernel + GNU
tools is in the U*X pack.
The only OS which I know for sure that 1) has a pov version 2) has nothing
like DLLs is MS-DOS. So, should you decide that MSDOS is dead (well,
actually it was never alive...) you can assume that you have the .dll/.so
capability in ANY case.
With respect to optimizations, you should not put too-atomic ops into
separate code, but try to create macro-ops which, even with the added
overhead of call, gain speed (I don't know if it is possible). A proposal
for a custom compile: create a multithreaded engine which can take advantage
of multi CPU boards (render a different set of lines on each CPU and merge
the result.). The speedup would be almost linear (what about a quad 1GHz
Athlon PC?)
