+current font (only valid for TrueType/OpenType/PostScript fonts loaded
+`natively', not TFM-based fonts). The left and right
+measurements are the glyph sidebearings, measured `inwards' from the
+origin and advance respectively, so for a glyph that fits completely
+within its `cell' they will both be positive; for a glyph that
+`overhangs' to the left or right, they will be negative. The actual
+width of the glyph's bounding box, therefore, is the character width
+(advance) minus both these sidebearings. The top and bottom are
+measured from the baseline, like \TeX's height and depth; the height of
+the bounding box is the sum of these two dimensions.}
