This looks like a lot but its a few small changes.

Summary: standardized imageformat functions(make function names similar, and
parameters in same order where relavant), small code cleanups, and
added a description of how to add an image format to blender.

Kent

Specifics:
merged png_decode.c and png_encode.c to png.c and cleaned function calls.

fixed some spacing in IMB_imbuf_types.h

casting cleanups:
        intern/amiga.c
        intern/ham.c
        intern/iris.c

Modified switch statements to have a default type to insure values are set:
        intern/antialias.c

Initalization of some vars and make types similar.
        intern/bitplanes.c

cleaned function calls, and changed if else to if's with return:
        intern/jpeg.c

added {}'s in multidemensional arrays.
        intern/matrix.h

Made a little cleaner to read, and matched above changes.
        intern/readimage.c
        intern/writeimage.c
