527081 - Make handling of paletted images saner

Status: NEW

I was talking with Joe about how we handle paletted images. It didn't sounds that good. Here's my proposal:

- Start by decoding the first frame of a GIF to a paletted memory buffer.
- If there are frames that follow:
 - we know that we have an animated image that we're going to keep in paletted form.
 - decode the remaining frames into paletted form.
- Otherwise we have a single frame:
 - Convert from paletted to ARGB32 and discard the paletted buffer.

We still probably want this. At minimum, it will reduce the amount of memory animated GIFs use by a little bit.
