 Background:

 Plupload ships with a client-side upload resizer that was included with
 Core in 3.3 but had the action removed because of
 [http://core.trac.wordpress.org/ticket/19174 browser inconsistencies] so I
 implemented it as [http://wordpress.org/extend/plugins/enable-image-
 scaling-option-on-upload/ a plugin] at the time. Everything works just
 fine and dandy with zero problems except that the `resize_height` and
 `resize_width` vars are defaulted to the Large image sizes defined in
 media settings. It would be nice to be able to filter one or both of the
 dimensions outside the scope of the 'Large' size (when 'Original' becomes
 the same size as 'Large', you effectively lose an image size).

 Patch attached.

 You'll have to re-add this action to test:

 `add_action( 'post-upload-ui', 'media_upload_max_image_resize' );`
