* 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.
