Mozilla's next generation, high performance layout engine based on open
Internet standards such as HTML 4.0, CSS 1/2, XML 1.0, and the Document Object Model (DOM). NGLayout is also very fast.
NGLayout was designed to be used as a component independently from Mozilla. The Gnome project is using NGLayout in their new file manager thingy, Nautilus.
NGLayout was the first layout engine to sucessfully render the acid box test properly.
Sometimes refered to as Gecko by the Netscape marketdroids.
