/**
 * Describes primary purpose of the input widget. This information is
 * useful for on-screen keyboards and similar input methods to decide
 * which keys should be presented to the user.
 *
 * Note that the purpose is not meant to impose a totally strict rule
 * about allowed characters, and does not replace input validation. It
 * is fine for an on-screen keyboard to let the user override the
 * character set restriction that is expressed by the purpose. The
 * application is expected to validate the entry contents, even if it
 * specified a purpose.
 *
 * The difference between `GTK_INPUT_PURPOSE_DIGITS` and
 * `GTK_INPUT_PURPOSE_NUMBER` is that the former accepts only digits
 * while the latter also some punctuation (like commas or points,
 * plus, minus) and “e” or “E” as in 3.14E+000.
 *
 * This enumeration may be extended in the future; input methods
 * should interpret unknown values as “free form”.
