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.

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 gif dispose handling for DISPOSE_BACKGROUND and DISPOSE_PREVIOUS
...
- Add 'scratch' field to gif that holds temporary 'scratch buffer' used for rendering frames
- For DISPOSE_BACKGROUND: Set background color to transparent instead of 0
- For DISPOSE_BACKGROUND: Write background pixels into scratch after rendering current frame, so it will be used in next frame
- For DISPOSE_PREVIOUS: Save frames that are not disposed into 'previous' field in gif, when DISPOSE_PREVIOUS is specified start with that previous frame. see http://webreference.com/content/studio/disposal.html
