This information is all easily available: just look at the definitions
of the structures. For a sample, it is:

        sizeof(SAMPLE) + sample->len;

For a bitmap:

        sizeof(BITMAP) + (bmp->h * sizeof(char *)) + (bmp->w * bmp->h);

RLE sprites, MIDI files, etc, can be measured in a similar manner...
