Advanced TextMetrics properties unavailable for Chromium < 77 #48
Description
When using maplibre-gl with older browsers, including Chromium < 77 which is still used by a majority of my users, all glyphs and symbols will be missing due to the lack of advanced TextMetrics support.
There are still 1 in 50 guys using these browsers, so I was wondering if we could still keep the backward compatibility, then some oldish browsers can still render maps properly with tiny-sdf!
