This code is before my time, but it seems like its not quite scaling the
image as maximally as requested.  There's probably a good reason...

Most of the explosion code (the code that places the explosions into the
model) are in client/cl_fx.c client/cl_newfx.c see CL_ExplosionParticles in

For the code where the a rocket (or whatever) hitting something is turned
into calls to CL_ExplosionParticles etc. check out CL_ParseTEnt in cl_tent.c

The code is mildly convoluted, I don't think Id was really focused on clean
design ;-)

Hope that helps.
