Tag Clouds

[mdawaffe]

#3723 introduces tags to WP core. Here's a port of bbPress tag cloud generating functions.

wp_generate_tag_cloud( $tags, $args )

Feed it prefetched tags (get_tags()) and some arguments that determine the sizes of the fonts in the cloud. Generic function that can accept whatever tags you throw into it (related tags, tags found on posts in category X, tags that start with Q, least used tags, whatever).

wp_tag_cloud( $args )

Grabs top tags and feeds them to wp_generate_tag_cloud().

wp_parse_args( $args, $defaults )

Helper function ryan and I would like to see fully adopted for 2.3.

Tweaks get_tags().

Small bug and use of wp_parse_args().

Forgot to mention wp_generate_tag_cloud() can output a whitespace separated list, a UL/LI list, or a raw array of links.

(In [5234]) Tag clouds from mdawaffe. fixes #4129
