c1f1a7c1b3 improve sharpen for screen work 
it was a bit granular (since it was designed for offset work), make sharpen
easier to adjust for smaller effects

- new 'sigma' parameter
- greater parameter range
- more self-tests

01238a0fd5 more progressive jpg changes 
- Remove the nocache stuff for prog jpg images. There was no saving in
  practice, since operations downstream could be cached.

  nocache is for objects that can change, not for memory saving

- Call _destroy on the decompress object much earlier, it frees a huge
  amount of memoey for prog jpg images.

6f94cb5ed4 don't cache progressive jpg images 
progressive jpg images need loads of memory, we shouldn't cache them by
default ... our called can hold a ref if they want to keep the image
around

ef6d8f5979 make test for matlab files more specific 
Previously vips just called Mat_Open() to test if a file was a Matlab
save file, but this is rather unreliable. For example, some JPEG files
can crash libmatio, and it can incorrectly think that at least some JP2
files are Matlab save files.

Instead, look for "MATLAB 5.0" at the start of the file. This is really too
specific, the first 116 bytes of a Matlab save file are freeform text,
but in practice all Matlab writers use the first few bytes to record the
file type.

8e667fbb3e still not quite there 
works, but is no faster, how odd

john@kiwi:~/pics$ time vips magickload nipguide.pdf[40] x.tif
real	0m0.244s
user	0m0.212s
sys	0m0.040s

$ time vips magickload nipguide.pdf x.tif --page 40
real	0m7.035s
user	0m6.900s
sys	0m0.152s

both give same result
