/**
* Font fingerprinting.
*
* Render serif, sans-serif, and monospace font
* in a span and collect the offsetWidth and
* offsetHeights.
*
* Once we gather this information, we can render
* a list of various fonts with serif, sans-serif,
* and monospace as fallbacks.
*
* If we compare the offsetWidth and offsetHeights
* of these new elements to the ones we collected
* initially we can determine if the user has the
* font installed on their system.
*
* Example from my M1 13 inch Macbook Air:
*
* serif:
* offsetWidth: 1653
* offsetHeight: 105
*
* sans-serif:
* offsetWidth: 1779
* offsetHeight: 104
*
* monospace:
* offsetWidth: 2160
* offsetHeight: 104
*
* If we test a font we already have, lets say Geneva, we would define the CSS as:
* font-family: "Geneva", serif; or
* font-family: "Geneva", sans-serif; or
* font-family: "Geneva", monospace;
*
* Geneva:
* offsetWidth: 2005
* offsetHeight: 113
*
* These numbers don't align with any of the fallback values so that means the font exists
* on our machine..
*
* However, let's try a font we don't have:
*
* Lobster:
* offsetWidth: 1653
* offsetHeight: 105
*
* These values match the serif font values which means it fell back because the font doesn't exist.
*
* If this happens, push the index of the font into an array, sort it, join it by commas and
* that's what this function returns.
*
