5.19.9 Italic Corrections
-------------------------

When typesetting adjacent glyphs from typefaces of different slants, the
space between them may require adjustment.

 -- Escape sequence: \/
     Apply an "italic correction": modify the spacing of the preceding
     glyph so that the distance between it and the following glyph is
     correct if the latter is of upright shape.  For example, if an
     italic 'f' is followed immediately by a roman right parenthesis,
     then in many fonts the top right portion of the 'f' overlaps the
     top left of the right parenthesis, which is ugly.  Use this escape
     sequence whenever an oblique glyph is immediately followed by an
     upright glyph without any intervening space.

 -- Escape sequence: \,
     Apply a "left italic correction": modify the spacing of the
     following glyph so that the distance between it and the preceding
     glyph is correct if the latter is of upright shape.  For example,
     if a roman left parenthesis is immediately followed by an
     italic 'f', then in many fonts the bottom left portion of the 'f'
     overlaps the bottom of the left parenthesis, which is ugly.  Use
     this escape sequence whenever an upright glyph is followed
     immediately by an oblique glyph without any intervening space.
