The following commits neglected to amend tst_QImageReader::supportsOption() with the ImageOption enumerators they added to QImageIOHandler: - c0ba249a48fd85ee8e047ff47448a4ed32d6cd91 - 163af2cf53d3441b453744b99254c07a175af5de - ba323b04cd78fb43e9e63b891e973d24b08250af Fix first and foremost by adding the missing ImageOption::ImageFormat to the list of PNG-supported formats (which, curiously enough, predates the public history and therefore the above three commits), and second, by rewriting the whole test function to enable -Wswitch, so further additions are less likely to be forgotten.
