 WordPress's oembed support follows the spec quite nicely, but doesn't
 really allow for expandability.

 In particular, the fetch() function in WP_oEmbed only realistically allows
 for maxwidth and maxheight parameters. Adding onto these parameters isn't
 easily possible.

 Modifying the fetch function to support arbitrary parameters from the
 embed shortcode to be passed on to the provider, as per provider support,
 is relatively easy, but can't be done with a plugin due to the lack of
 filters.

 Example: https://dev.twitter.com/docs/api/1/get/statuses/oembed

 Simple patch attached to support arbitrary filters.

 Example of an embed code after the patch, using the align parameter to
 pass align=center to twitter's oembed call:

 [embed
 align=center]https://twitter.com/Otto42/status/210198339386482688[/embed]
