1009126 - Use multiple progress indicator images

Status: RESOLVED DUPLICATE of bug 759252

When loading multiple tabs, they all look identical. I'm assuming this is because they all use the same apng (or svg?) and so only actually get loaded into memory once and drawn into multiple places. This is really noticable when restoring a bunch of tabs at once (which we don't really do anymore, so... opening a folder of bookmarks?)

What if we used multiple images with different starting offsets? Or it might even just be enough to have different copies of the same image. Or maybe there's some magical graphics things I don't know about (not impossible) that allows us to not reuse the same rendering.

Now might be an interesting time to experiment with the new progress indicators.

The previous indicators had the same behavior. When we switch to a CSS animation this will no longer occur since they will have different starting times.
