-opens the given font(s), loads and renders all glyphs at the given ppem
-value, and reports failing glyphs if there are less than ten fails, or the
-number of fails only if there are more fails.
+opens the given font(s), loads and renders glyphs at the given ppem value.
+For successfully rendered glyphs, it calculates the bitmap MD5 checksum
+for regression testing as well as horizonal (X) and vertical (Y) acutances
+for quality assessment.  The acutance is equal to 2.0 for monochrome bitmap
+fonts and approaches this value for hinted anti-aliased fonts.
