/* Use this script when you want to test APIs that use vendor prefixes
and define which objects need to be checked for prefixed versions, à la
<script src="vendor-prefix.js"
data-prefixed-objects='[{"ancestors":["navigator"], "name":"getUserMedia"}]'
data-prefixed-prototypes='[{"ancestors":["HTMLMediaElement"],"name":"srcObject"}]'></script>
data-prefixed-objects lets prefix objects in the global space
data-prefixed-prototypes adds prefixes to interfaces, for objects that
get created during the tests
NB: vendor prefixes are expected to go away in favor of putting
new features behind flag, so hopefully there will be only limited
need to use this
