21912	Add return filter to current_theme_supports()	DJPaul		"current_theme_supports() makes it hard for plugins to affect whether a theme supports a certain feature. 

The use case I have is that I am building a plugin that utilises bbPress (and soon, BuddyPress)-style template compatibility parts. In those template parts, I display something very, very similar to a post thumbnail or custom header. I want to use the ""Featured Image"" metabox on the Post screen to set that image.

If I use the plugin on a theme that doesn't support post thumbnails, the metabox correctly doesn't appear, and so users have no way of choosing a featured image. While there are ways around this -- manual conditional registering of the Featured Image metabox, creating my own metabox, or calling add_theme_support/remove_theme_support like a toggle -- none of them are particularly elegant.

While current_theme_supports has a return filter, it's not reached by all code execution paths. The attached patch reworks the function so that the return value is always passed through the filter."	enhancement	new	normal	Awaiting Review	Themes	3.4	normal		has-patch
