示例1: IsResolution
bool Parser::IsResolution(const string_t& str)

// Using a regex such as "\\d{3,4}(p|(x\\d{3,4}))$" would be more elegant,
// but it's much slower (e.g. 2.4ms -> 24.9ms).
// *###x###*
if (str.size() >= 3 + 1 + 3)
{
size_t pos = str.find_first_of(L"xX\u00D7"); // multiplication sign
if (pos != str.npos)
