2ce79d76a0 output double histogranms for large images 
since images with more than 2*32 pixels will overflow a uint accumulator

29599e00eb avoid NaN in mapim 
We were not avoiding NaN in float transform images, leading to segvs in
some cases.

Thanks afontenot

d8ed630d77 better 8/16 bit casting for pngsave 
pngsave was just using the image format to decide whether to save as 8
or 16 bit PNG. With this patch it checks Type as well.

This means that eg. a uint32 image tagged as sRGB will save as png8, but
a uint32 image tagged as RGB16 will save as png16.

e1a9397c15 better error detection in spngload 
Do a speculative spng_get_trns() in header read to force all chunks to
be parsed.

98be88bf80 add sourceginput 
This is a source which wraps a GInputStream. You can use this to eg.
efficiently load a PNG file from a GFile object.

b2fa1f89e8 revise ppmload, fixing a couple of bugs 
- ppmload was not setting interpretation, filename, etc. for files read via
  mmap
- files not read via mmap were never byteswapped
- some cleanups

3996f3279b fix range clips for casts to and from int 
Fix two bugs:

- clip in casts from int32 and uint32 could overflow -- do these as gint64 now

- clip in casts from float to int could overflow since float32 can't
  represent the full range of int32 without losing precision -- do these
  as double

And add some more tests.

Thanks ewelot.

2585565b3e better test for output to target 
We used to enable write to stdout if the first character of an output filename
was ".", eg.:

	vips copy x.jpg .png

But this will also enable write to stdout for things like:

	vips copy x.jpg ./y.png

This patch also tests that the rightmost "." in a filename is also the
first character.

acc579cc9d force binary mode for connections on win 
stdin / stdout (for example) are created in text mode by default on
win. We need to flip them to binary mode for connection read and write.
