LibGfx: Google Doodle Issue #2 and download GIF issue

[Lubrsi]

Here's how the current Google doodle appears:

I imagine it has something to do with this:

Unexpected application extension size: 1135

For some reason, it doesn't start animating until you resize the window.

While I was at it, I noticed the download GIF nows shows a background colour when the page flies across:

That might be an ICC profile, starting at offset 0x320. it's the first app extension that appears in the file, and it just defines color stuff, so likely not related to that issue.

Looks like an interlaced animated GIF :)

It does for me. Looks the same, though.

Thanks, will have a look at adding support for interlaced GIFs at the weekend 😄

I saw this same thing in a previous Google Doodle and it was some embedded XMP metadata that was not necessary to decode the image itself. Possibly the same thing here.
