Could you provide patches as git commits (google for git format-patch). I am not sure about the problem that you are fixing. If the extents are large enough to overflow the fixed point calculations, wouldn't other code (which also uses the fixed point numbers) possibly run into the same overflows? So while I agree that fixing this is a good idea, I am not sure that this actually means that it becomes safe to use a recording surface with large-ish coordinates.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
