73436ddfc2 add @properties flag to tiffsave 
writes all vips metadata to imagedescription tag

0deb640bc4 load and save TIFFTAG_IMAGEDESCRIPTION 
this often has useful metadata in, for example the OME spec has all the
metadata in there as an XML document

1504ca7cdc have a more formal max image dimension 
we now have VIPS_MAX_COORD for maximum image dimension, set to 10m
pixels ... we could go up to 2bn, but 10m seems a reasonable max, at
least for now

2409767679 add vips_image_new_from_memory_copy() 
takes a copy of a memory area when making an image ... this helps bindings
for languages which don't have much control over memory

2b46b7e889 many more const decls 
ruby gobject-introspection is quite fussy about needing a lot of const
declarations ... these changes help vips_image_matrix_from_array()
appear in Ruby

7495690cd6 remove vips__image_sizeof_bandformat 
we had main API macros which used an array behind the scenes,
vips__image_sizeof_bandformat[]. Swap this for a function,
vips_format_sizeof(), to help DLLs.

the array symbol is still there for compatibility
