The code resides in coders/tiff.c in ImageMagick or GraphicsMagick as
obtained from CVS or a source distribution. Without reviewing the
code and learning what IFDs/subIFDs are, I can't answer the second
question.
The writing is done by WritePTIFImage, but this is just a simple
wrapper which successively reduces the image size and hands off the
work to the normal TIFF writer, with tiling enabled.
This code was written by Bill Radcliffe, who may still be lurking on
this list.
