## nfontmetrics

Arguments: stream fontmetrics

Modifies as necessary and returns the specified `fontmetrics` object so it describes the current font of stream.

This destructive version of fontmetrics may be useful for avoiding consing a lot of `fontmetrics` objects if frequent calls are required; this could be done by calling make-fontmetrics just once to create a single utility `fontmetrics` object, and then passing it to nfontmetrics each time a call to this function is needed (using the object temporarily within a single process where re-entrancy is not an issue).
