Abstract: Content can be flowed through one or more containers that can be laid out analogously to printed material. Content is flowed into the first specified container until that container is “full” of content. Subsequent content is then flowed through subsequent containers, each of which is individually identified, and whose ordering is specified independently of their position and visual presentation. Multiple independent sources of content can be flowed through multiple independent collections of containers. Each container can format the content presented within it independently from other containers, and each container can comprise script, or other programmatic constructs, which can operate on, and modify, the content flowed into such a container. To provide for the rich layouts, content containers can be nested inside one another such that multiple layers, or levels, of the layout can be edited independently of one another.

Abstract: Techniques involving dynamic colorization of graphical user interfaces. One representative technique includes enabling a user to specify colors in which user interface elements will be colored in an application. An application colorization service is initiated in response to the user specification of the colors, which is used at least to obtain the colors specified by the user, and to create bitmap images of the application's user interface elements using the user-specified colors. A bitmap image output location is made accessible to the application to enable the application to retrieve the created bitmap images, and present the application using the application user interface elements having the user-specified colors.

Abstract: Many computer applications incorporate and support animation (e.g., interactive user interfaces). Unfortunately, it may be challenging for computer applications and rendering systems to render animation frames at a smooth and consistent rate while conserving system resources. Accordingly, a technique for controlling animation rendering frame rate of an application is disclosed herein. An animation rendering update interval of an animation timer may be adjusted based upon a rendering system state (e.g., a rate of compositing visual layouts from animation frames) of a rendering system and/or an application state (e.g., a rate at which an application renders frames) of an application. Adjusting the animation rendering update interval allows the animation timer to adjust the frequency of performing rendering callback notifications (work requests to an application to render animation frames) to an application based upon rendering system performance and application performance.
