PRESTO (LAYOUT ENGINE)

'Presto' is the name of the current (Opera 9 series) layout engine for the Opera web browser developed by Opera Software. It was first released (following several public betas and technical previews) on January 28, 2003 in Opera 7.0 for Windows. Presto replaced the Elektra engine used in versions 4–6 of Opera. Presto differs from Elektra in that it is dynamic: the page or parts of it can be re-rendered in response to DOM and script events. The Presto layout engine is only available 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.
