+Under Mozilla 1.7, VideoLink sets the assumed screen resolution to
+40 dpi, which I reckon to be the average resolution of a standard
+definition TV display.  This should mean that text with a font size
+expressed in millimetres or points will appear around the specified
+size.  Unfortunately this setting has a different effect under
+Mozilla/XULRunner 1.8:
+
+Mozilla   Assumed    Requested     Actual size
+version  resolution    size     (pixels) (inches)
+           (dpi)
+
+  1.7    default:96    20 px       20      0.5
+  1.7    default:96    36 pt       48      1.2
+  1.7        40        20 px       20      0.5
+  1.7        40        36 pt       20      0.5
+  1.8    default:96    20 px       20      0.5
+  1.8    default:96    36 pt       48      1.2
+  1.8        40        20 px       48      1.2
+  1.8        40        36 pt       48      1.2
+
+From version 0.10, until I have a proper solution, VideoLink will not
+set the assumed screen resolution under Mozilla 1.8.  I must advise
+against using font sizes in millimetres or points since they will vary
+between browser versions.
