a252a35794 insert should be smalltile 
Joins can get very wide (eg. consider joining a set of tiles horizontally
to make a large image), we don't want mem use to grow as O(N**2). SMALLTILE
will guarantee we keep small and local.

38819a9050 better dzsave temp dir name

get lost

78acd9b7a0 use a better name for the dzsave temp dir 
see https://github.com/jcupitt/libvips/issues/242

dzsave with deepzoom layout and fs container writes a temp dir called
dzsave-temp-324857 or similar, and makes sure that this directory does
not exist

after write, the foo_files and foo.dzi files are picked out to the
current dir and the temp removed
