    x11-toolkits/pangox-compat: fix build with clang 16

    Clang 16 has a new error about incompatible function types, which shows
    up when building x11-toolkits/pangox-compat:

    basic-x.c:687:23: error: incompatible function pointer types assigning to
'void (*)(PangoEngineShape *, PangoFont *, const char *, unsigned int, const
PangoAnalysis *, PangoGlyphString *, const char *, unsigned int)' (aka 'void
(*)(struct _PangoEngineShape *, struct _PangoFont *, const char *, unsigned
int, const struct _PangoAnalysis *, struct _PangoGlyphString *, const char *,
unsigned int)') from 'void (PangoEngineShape *, PangoFont *, const char *,
gint, const PangoAnalysis *, PangoGlyphString *)' (aka 'void (struct
_PangoEngineShape *, struct _PangoFont *, const char *, int, const struct
_PangoAnalysis *, struct _PangoGlyphString *)')
[-Wincompatible-function-pointer-types]
      class->script_shape = basic_engine_shape;
                          ^ ~~~~~~~~~~~~~~~~~~

    This is because the 'script_shape' callback function in pango 1.50 has
    the 'length' argument as 'unsigned int', and also two additional
    parameters 'paragraph_text' and 'paragraph_length'. Even though it looks
    like this callback function is never used, correct the arguments to fix
    the error.
