Presto (layout engine)
From MedBib.com - Medicine & Nature
Presto is a layout engine for the Opera web browser developed by Opera Software. After several public betas and technical previews, it was released on January 28, 2003 in Opera 7.0 for Windows; it is the browser's current layout engine. Presto replaced the Elektra engine used in versions 4–6 of Opera. Unlike Elektra, Presto is dynamic: the page or parts of it can be re-rendered in response to DOM and script events. Presto is available only as a part of Opera browser or related products. The source or binary (DLL) forms of the engine are not publicly available. Subsequent releases have seen a number of bugs fixed and optimisations to improve the speed of the ECMAScript ("JavaScript") engine.
JavaScript engines
Two JavaScript engines are used in combination with Presto. The "linear_b" engine is used in versions based on the "Core" fork of Presto, Opera 7.0 through 9.27.[1] The "futhark" engine is used in versions based on the "Core 2" fork of Presto, Opera 9.5 and will be used in Opera 10.[2]
