Various embodiments utilize a layout viewport and a visual viewport separate from the layout viewport. The layout viewport is utilized for such things as page layout operations and reporting Document Object Model values to script. The layout viewport can be thought of as an initial rectangle which is equivalent in size to the initial containing block. The initial containing block is a containing block that contains web content that is initially visible to the user. The visual viewport is separate from the layout viewport and is allowed to be freely manipulated relative to the layout viewport. For example, the visual viewport may 'push' the layout viewport around when it collides with the layout viewport boundaries. The visual viewport can be thought of as the rectangle that is visible to the user.

Virtual viewport and fixed positioning with optical zoom

In one or more embodiments, a framework is provided in which image decoding can be delayed based on heuristics, and later initiated based on a use type associated with the image or the likelihood that the image is going to be used. For example, a use history and priority system can enable images that are currently being rendered and/or are likely to get rendered to be decoded before images that have a history of being downloaded but never used. Accordingly, by decoupling image download from image decoding, CPU resources and memory can be more efficiently utilized.

Delayed image decoding

Various embodiments enable repetitive gestures, such as multiple serial gestures, to be implemented efficiently so as to enhance the user experience. Other embodiments provide various approaches to zoom operations that consider a particular element's contextual surroundings in making a zoom decision that is designed to enhance the user experience and provide efficiently-zoomed content given a device's or rendering container's form factor.

Input pointer delay and zoom logic

The present visibility-aware service reduces power-intensive activities when a window associated with the visibility-aware service is not visible. The window is not visible when the window is minimized or when the window is switched from a foreground position to a background position on a display.
