MIME Type Icons¶
MIME type icons are used to depict documents and files. They come in four sizes: 16px, 22px, 32px, and 64px. MIME type icons use the monochrome style for 16px and 22px sizes, and the colorful style for 32px and 64px sizes.

For video files, the background is a horizontal rectangle that looks like a filmstrip:

For audio files, the background is a CD sleeve with a CD partially visible:

For documents and everything else, the background is a vertical rectangle with the top-right corner folded over, and the fold casts a shadow:

As with the Places icons, the foreground symbol does not cast a shadow.
