6804ff61df load non-transparent GIFs as RGB 
And GIFs with transparent elements as RGBA. This can make downstream
processing (eg. in vipsdisp) much quicker since it can save a
composite.

03f76b73b4 add "premultiply" param to tiffsave 
Some programs, like indesign, only work with premultiplied alpha in TIFF. To
make TIFFs which are compatible with these programs, we'll need an extra
TIFF save flag (perhaps premultiply?) to premultiply alpha and save as
EXTRASAMPLE_ASSOCALPHA.

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.
