Always good to get a concensus.

I beleive so.  But I'm not yet sure how best to do it.  libz has a
function that reads in files, uncompressing those that are
compress(1)ed or gzip(1)ed and reading other files as is.  One could
read the file into mem with that and call FT_New_Memory_Face on the
resulting buffer.  But is that the best way to do it?

I'm concerned about the memory pressure from reading the whole file
into heap.  But I don't see any way around it.

In any case, I think ftcommon.i's install_font_file() will need
significant reimplimentation to best explain to other ft users (that
is the intent of ft2demos, yes?) how best to uncompress on the fly.
