/******************************************************************************
 * Variant-Formats {OLEAUT32}
 *
 * NOTES
 *  When formatting a variant a variety of format strings may be used to generate
 *  different kinds of formatted output. A format string consists of either a named
 *  format, or a user-defined format.
 *
 *  The following named formats are defined:
 *| Name           Description
 *| ----           -----------
 *| General Date   Display Date, and time for non-integer values
 *| Short Date     Short date format as defined by locale settings
 *| Medium Date    Medium date format as defined by locale settings
 *| Long Date      Long date format as defined by locale settings
 *| Short Time     Short Time format as defined by locale settings
 *| Medium Time    Medium time format as defined by locale settings
 *| Long Time      Long time format as defined by locale settings
 *| True/False     Localised text of "True" or "False"
 *| Yes/No         Localised text of "Yes" or "No"
 *| On/Off         Localised text of "On" or "Off"
 *| General Number No thousands separator. No decimal points for integers
 *| Currency       General currency format using localised characters
 *| Fixed          At least one whole and two fractional digits
 *| Standard       Same as 'Fixed', but including decimal separators
 *| Percent        Multiply by 100 and display a trailing '%' character
 *| Scientific     Display with exponent
 *
 *  User-defined formats consist of a combination of tokens and literal
 *  characters. Literal characters are copied unmodified to the formatted
 *  output at the position they occupy in the format string. Any character
 *  that is not recognised as a token is treated as a literal. A literal can
 *  also be specified by preceding it with a backslash character
 *  (e.g. "\L\i\t\e\r\a\l") or enclosing it in double quotes.
 *
 *  A user-defined format can have up to 4 sections, depending on the type of
 *  format. The following table lists sections and their meaning:
 *| Format Type  Sections Meaning
 *| -----------  -------- -------
 *| Number       1        Use the same format for all numbers
 *| Number       2        Use format 1 for positive and 2 for negative numbers
 *| Number       3        Use format 1 for positive, 2 for zero, and 3
 *|                       for negative numbers.
 *| Number       4        Use format 1 for positive, 2 for zero, 3 for
 *|                       negative, and 4 for null numbers.
 *| String       1        Use the same format for all strings
 *| String       2        Use format 2 for null and empty strings, otherwise
 *|                       use format 1.
 *| Date         1        Use the same format for all dates
 *
 *  The formatting tokens fall into several categories depending on the type
 *  of formatted output. For more information on each type, see
 *  VarFormat-Dates(), VarFormat-Strings() and VarFormat-Numbers().
 *
 *  SEE ALSO
 *  VarTokenizeFormatString(), VarFormatFromTokens(), VarFormat(),
 *  VarFormatDateTime(), VarFormatNumber(), VarFormatCurrency().

/******************************************************************************
 * VarFormat-Strings {OLEAUT32}
 *
 * NOTES
 *  When formatting a variant as a string, it is first converted to a VT_BSTR.
 *  The user-format string defines which characters are copied into which
 *  positions in the output string. Literals may be inserted in the format
 *  string. When creating the formatted string, excess characters in the string
 *  (those not consumed by a token) are appended to the end of the output. If
 *  there are more tokens than characters in the string to format, spaces will
 *  be inserted at the start of the string if the '@' token was used.
 *
 *  By default strings are converted to lowercase, or uppercase if the '>' token
 *  is encountered. This applies to the whole string: it is not possible to
 *  generate a mixed-case output string.
 *
 *  In user-defined string formats, the following tokens are recognised:
 *| Token  Description
 *| -----  -----------
 *| '@'    Copy a char from the source, or a space if no chars are left.
 *| '&'    Copy a char from the source, or write nothing if no chars are left.
 *| '<'    Output the whole string as lower-case (the default).
 *| '>'    Output the whole string as upper-case.
 *| '!'    MSDN indicates that this character should cause right-to-left
 *|        copying, however tests show that it is tokenised but not processed.
