I can't see any mention that support for Text is optional. Is it reasonable with browsers approaching major releases ? The TextMetrics MUST return have 2 Float readonly properties : the width and height. The width alone is not enough. The methods fillText() and strokeText() could have a 5th optional boolean argument called wrapText ( false by default ) to specify if the text should wrap or the font-size be decrease in case the text is wider than maxWidth. It is unclear whether the transformations affect the text. -- Mathieu 'p01' HENRI JavaScript developer, Opera Software ASA
