Also, pushClipRet really needs the bClip parameter. It prevents leaf<br>nodes from setting their own clip rectangle. Images and other leaf nodes<br>have clip rects that are exactly as big as the item itself, so they<br>don't really clip anything.

But: the stencil buffer is never<br>antialiased, so we'll have jaggies at the edges if we clip.</blockquote><div> </div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
