/*
* This test pokes around in platform folders/directories to try
* to find some fonts with which to test. It will do different things
* on different platforms and may not do anything at all if the platform
* directories aren't where it expects. For example if /usr/share/fonts
* is not used on a particular Linux distro or on Windows the fonts are
* not in c:\windows\fonts (which would be the right place on 99.99% of
* systems you will find today.
* It ought to be very reliable but it is not 100% guaranteed.
* Failure to find fonts to test is 'not a product bug'.
* Fonts on a system having different content than we expect based on
* file extension is also 'not a product bug'.
* The former will cause silent success, the latter may cause 'noisy' failure
* and the test would then need to be dialled back to be more cautious.
