+PostScript glyph drawing operations can be expressed in multiple different

+``hlineto`` operator which draws a horizontal line, removing the need to
+specify a ``dx`` coordinate, and a ``vlineto`` operator which draws a
+vertical line, removing the need to specify a ``dy`` coordinate. As well
+as decompiling :class:`fontTools.misc.psCharStrings.T2CharString` objects

+    #

+    #  - 'h' for horizontal, ie. zero X and non-zero Y,
+    #  - 'v' for vertical,   ie. non-zero X and zero Y,
+    #  - '0' for zeros,      ie. zero X and zero Y.
+    #
+    # The '0' pseudo-operators are not part of the spec, but help simplify the following
+    # optimization rounds.  We resolve them at the end.  So, after this, we will have four
+    # moveto and four lineto variants:
+    #
+    #  - 0moveto, 0lineto
+    #  - hmoveto, hlineto
+    #  - vmoveto, vlineto
+    #  - rmoveto, rlineto
+    #
+    # and sixteen curveto variants.  For example, a '0hcurveto' operator means a curve
+    # dx0,dy0,dx1,dy1,dx2,dy2,dx3,dy3 where dx0, dx1, and dy3 are zero but not dx3.
+    # An 'rvcurveto' means dx3 is zero but not dx0,dy0,dy3.
+    #
+    # There are nine different variants of curves without the '0'.  Those nine map exactly
+    # to the existing curve variants in the spec: rrcurveto, and the four variants hhcurveto,
+    # vvcurveto, hvcurveto, and vhcurveto each cover two cases, one with an odd number of
+    # arguments and one without.  Eg. an hhcurveto with an extra argument (odd number of
+    # arguments) is in fact an rhcurveto.  The operators in the spec are designed such that
+    # all four of rhcurveto, rvcurveto, hrcurveto, and vrcurveto are encodable for one curve.
+    #
+    # Of the curve types with '0', the 00curveto is equivalent to a lineto variant.  The rest
+    # of the curve types with a 0 need to be encoded as a h or v variant.  Ie. a '0' can be
+    # thought of a "don't care" and can be used as either an 'h' or a 'v'.  As such, we always
+    # encode a number 0 as argument when we use a '0' variant.  Later on, we can just substitute
+    # the '0' with either 'h' or 'v' and it works.
+    #
+    # When we get to curve splines however, things become more complicated...  XXX finish this.
+    # There's one more complexity with splines.  If one side of the spline is not horizontal or
+    # vertical (or zero), ie. if it's 'r', then it limits which spline types we can encode.
+    # Only hhcurveto and vvcurveto operators can encode a spline starting with 'r', and

+
+    This class merges multiple files into a single OpenType font, taking into
+    account complexities such as OpenType layout (``GSUB``/``GPOS``) tables and
+    cross-font metrics (for example ``hhea.ascent`` is set to the maximum value
+    across all the fonts).
+
+    If multiple glyphs map to the same Unicode value, and the glyphs are considered
+    sufficiently different (that is, they differ in any of paths, widths, or
+    height), then subsequent glyphs are renamed and a lookup in the ``locl``
+    feature will be created to disambiguate them. For example, if the arguments
+    are an Arabic font and a Latin font and both contain a set of parentheses,
+    the Latin glyphs will be renamed to ``parenleft.1`` and ``parenright.1``,
+    and a lookup will be inserted into the to ``locl`` feature (creating it if
+    necessary) under the ``latn`` script to substitute ``parenleft`` with
+    ``parenleft.1`` etc.
+
+    Restrictions:
+
+    - All fonts must have the same units per em.
+    - If duplicate glyph disambiguation takes place as described above then the
+      fonts must have a ``GSUB`` table.
