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.

1e015654c3 deprecate heifload autorotate 
heifload autorotate is now always on, and we always delete EXIF
orientation tags. If a HEIC image fails to rotate upright, at least it's
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

John Cupitt
d1094847a3 remove no-alpha webp support 
We used to try to spot webp images with no alpha and load them as plain
RGB, but it turns out this is difficult to do reliably, especially
for animated images.

This patch simply removes support, so all webp images now load as RGBA.
