The HTML Media Element resource selection algorithm provides a way to select
between multiple resources specified using the <source> element according to
two criteria
- whether the 'type' attribute is supported by the media element
- whether the 'media' attribute 'matches the current environment'

The 'media' attribute is a media query and can be used, for example, to specify
different resources for different screen sizes.

MSE apps need a way to do the same kind of resource selection, but currently we
only have a way to check type support using 'isTypeSupported'.

We need a way to check whether a media query 'matches the current environment'.
