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

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.
