Wrong MIME type when converting asset

[renaatdemuynck]

I am working on a filter that converts fonts to different formats (e.g. when I request 'myfont.woff' it will convert it on-the-fly from 'MyFont.OTF'). The problem is that the MIME type will be application/x-font-opentype instead of application/woff. I've tried setting the mime type of the asset inside the filter but it is being overwritten later by one of the resolvers. So I thought "How does the MimeResolver do this for LESS assets?". Apparently this works as expected for LESS files because the mime type for LESS is text/css (which technically isn't correct) (The same goes for SASS and CoffeScript too). The problem seems to be that the MIME type is being determined based on the source asset and not on the extension of the requested asset. Simply changing the behavior of determining the MIME type would break BC. So how and where could this be fixed? (Or am I missing something here?)

@renaatdemuynck I agree that it should use the mime type of the requested asset.

It might also miss some mappings (I didn't check yet). I'm personally down with a BC-break for this, as it's invalid behavior.

Ok, I will fix this and create a pull request
