When using swf() in custom modules and themes you are able to provide html_alt in the options array to provide custom alternate text. This is very useful but recently it has been broken by the addition of a global filter on this text(74e8441c35fb6ca88b00090e6e612f9479745a5c). Filtering of user supplied input is code, but forced filtering of hard coded data can be frustrating.

I think the easiest workaround without further refactoring all everything around html_alt would be to allow an html_alt_format option that overrides the global variable.

I've gone ahead and marked this as major since its a regression of functionality and sites,modules,themes relying on this will be broken without changing the alt format.
