The glyphs cache only tracked the number of glyphs in the cache, which isn't very useful when the glyphs vary in size from a few bytes to dozens of megabytes. In terms of memory footprint, we are interested not just in the number of cached glyphs, but also in the total memory usage. We now track the pixel-size of each glyph and drop as many as necessary to fall below the set threshold which is currently 4 MBs. There was no performance loss observed after this patch on a diverse set of documents of all types (if anything, a very modest performance win was hinted in some cases), with significant memory reduction in some cases where dozens of megabytes were previously left stale in the cache.
