Extended with tiled background images

[ghost]

Extends background_fill with an extra argument tile.

Usage: Set background_fill to tile (eg background_fill=tile) and tile to an image path or url (eg `tile=http://domain.ext/image.jpg).

Example:

the_post_thumbnail( 'width=650&height=300&crop=1&resize=true&background_fill=tile&tile=path-or-url-to-tile-image' );

Please review before adding. Works for me but was coded quite fast.

A fallback to solid fill needs to be added if no or invalid tile image was provided.

@daankortenbach how do you feel about making unit tests for this?

[ghost]

@joehoyle I was already looking into it. Can't promise any dates though.

I think this would probably be better as a WP Thumb addon plugin, as I think the functionality is not "mainstream", you can hook into wpthumb_image_post and subclass WP_Thumb_Background_Fill to make this pretty lightweight I'd think. Re-open if needed :)

Agreed, it's an edge case anyway.
