add fail-on : better control over loader error handling ( #2360 )
...
Instead of a simple fail/don't-fail boolean switch, add fail-on, an enum which sets the sensitivity of loaders to errors.
There's a new sensitivity level which tries to detect truncated images, but ignores other types of error.

gifsave: expose bitdepth property ( #2429 )
...
Provides control over the maximum number of colours in the output
image palette, making the API more closely match that of pngsave.
Lowering the bitdepth to 7 (from the default value of 8), which
halves the maximum number of colours from 255 to 127, typically
reduces encoding time by ~20%.

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.

Fix two bugs:

- 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.
