I was trying to accelerate path filling using stencil buffer, For<br>
antialiasing, we rely on GPU multisampling.<br>
So, I want to know Does webkit support Multisampling for accelerated<br>
2D Canvas? how to switch on it?<br>
Thanks for you help.<br></blockquote><div><br></div><span style="font-family:arial,helvetica,sans-serif;font-size:13px">I believe the details of this depend on which port you're using.</span><div style="font-family:arial,helvetica,sans-serif;font-size:13px">
