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.

d3ccadf212 revise unpremultiply, again 
We were not detecting division by zero carefully enough, nor clipping
the alpha range sufficiently in unpremultiply.

difficult test case
