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%.

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.

someone else's fault.

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
- Add "ANIMEXTS1.0" to Application Extension parser
- Graphic Control Extension parser refactor
- Compare file contents to expected images for animated gifs in foreign tests
