Unsafe /tmp usage in imagen about hevea HOT 2 OPEN

In my experience it pays off to create a single temporary directory as "root" dir
for all subsequent temporaries as soon as there are more than say one or two
temporary files. Cleanup will be simpler as only one directory must be blown away
on (whatever kind of) exit and maintenance will be simpler, too.

So, I'd like to suggest

IMAGEN_TMPROOT=$(posix_mktemp)
COM="$IMAGEN_TMPROOT/com"
TMPPNG="$IMAGEN_TMPROOT/png"

or something along that lines. Here follow up mkdir(1) calls are necessary, though.

Oh yeah, I almost forgot: speed! Only one invocation of m4(1). LOL.

Maybe, but I don't know how to do that :P
