c09dec0de1 Fixed jaggies in image resizing.
Split naming of T.81/T.42 type JPEG from normal JPEG. This is in preparation
for allowing the selective output of normal JPEG (like most people want)
and the T.81/T.42 type you might want for forwarding as T.37

365fc08719 Changed spandsp from using TRUE and FALSE to using C99 true and false. It seems
like the quirks we used to get using those with C++ have gone away.

df669f700a A cleanup of FAX image size/resolution matching accuracy. Squashing of bi-level
images should now be correct. This is now close to supporting grey scale and
colour.

45eaaf4178 Spandspi's FAX engine now gives separate size and resolution information about
the images on the line and the images in the file. The ties in with the recent
addition of image resizing and flattenign for colur images.

dfce47f26d Relaxed the constraints for declaring a clean end of call on FAX receive. If we
get an EOP, we no longer worry whether the final stages tidy up. This helps
tolerate the increasing number of VoIP calls which hang up before the audio has
flushed down the line.

A few little cleanups.
