-v9.4). </p> <p>The following diagram provides an overview of the Window Server

-</fig> <p>Below we list some of the key features of the Window Server, including
-differences between the two architectures. The term <b>surface</b> is used
-in ScreenPlay for a hardware-independent memory buffer for holding an image
-or part of a scene. The <b>UI surface</b> is a special surface onto which
-the Window Server renders all of the UI content. It is created automatically
-during system start up. An <b>external surface</b> is any other surface—for
-example, a surface that holds a video or to which OpenGL ES content is rendered. </p> <ul>
-<li id="GUID-A56D68E9-99E0-528A-9DDD-977BECE50A45"><p>The Window Server has
-a render stage framework, which enables the last stage of the Window Server
-rendering to be customizable through plug-ins called <b> render stages</b>.
-These can be chained to form a rendering pipeline, which takes the drawing
-operations that are produced by the Window Server and ultimately passes them
-to the UI surface. Render stages can selectively filter, modify, or redirect
-the draw operation stream, as required—for example, to perform transition
-effects (TFX). </p> </li>
-<li id="GUID-A6589F28-B8B5-5FBA-B241-6E526D6A9BF1"><p>In ScreenPlay, composition
-takes place in two stages. First, the render stages render the drawing to
-the UI surface. Then the composition engine combines the UI surface and any
-external surfaces into elements (sometimes called <b>layers</b>) and composes
-them to the screen. This enables the composition to be performed in software
-or hardware accelerator chips. </p> </li>
-<li id="GUID-BA8D10A1-F0CB-56F7-817B-F1425AC1DA56"><p>In the non-ScreenPlay
-variant, the concept of surfaces is not used and the Window Server composes
-directly onto the <b>frame buffer</b> which is then displayed on the screen. </p> </li>
-<li id="GUID-FC88013B-E5A4-5DD6-9906-A526D137CF43"><p>There are differences
-in the plug-in framework APIs in the two architectures. In addition, in ScreenPlay,
-fading effects are implemented by using render stages, whereas when ScreenPlay
-is not enabled they are implemented by using a separate fader plug-in type
-(not shown on the diagram). </p> </li>
-<li id="GUID-86A8FB36-B9DF-50F2-AE0B-798D717899A6"><p>In ScreenPlay, the Window
-Server provides advanced pointer features, such as support for multiple pointers
-and proximity and pressure coordinates. The non-ScreenPlay variant does not
-provide this support. </p> </li>
-<li id="GUID-46123A93-AF91-5FAB-995E-CDEAE9C8B961"><p>ScreenPlay provides
-support for externally connected displays, such as TV-out. The non-ScreenPlay
-variant considers the size of each display to be fixed. However, for High-Definition
-Multimedia Interface (HDMI) and composite video connectors, there are a range
-of resolutions that can change dynamically. ScreenPlay provides an optional
-feature that supports switching between resolutions at runtime and notifications
-to Window Server clients when there are changes to the resolution and connectedness. </p> </li>

+<entry><p>The client-side API library for remote graphic contexts in ScreenPlay.
+Remote graphic contexts store draw operations so that they can be played back
+later. It is "remote" because the draw operations are generally played back
+in a different location from where they are stored. For example, the draw
+operations are frequently stored on the client side and then a transformation
+engine uses them on the server side to make an effect. </p> </entry>
