+Description
+===========
+   The PointSprites sample shows how to use the new Direct3D point sprites
+   feature. A point sprite is simply a forward-facing, textured quad that is
+   referenced only by (x,y,z) position coordinates. Point sprites are most
+   often used for particle systems and related effects.
+
+   Note that not all cards support all features for point sprites. For more
+   information on point sprites, refer to the DirectX SDK documentation.

+User's Guide
+============
+   The following keys are implemented. The dropdown menus can be used for the
+   same controls.
+      <Enter>     Starts and stops the scene
+      <Space>     Advances the scene by a small increment
+      <F1>        Shows help or available commands.
+      <F2>        Prompts user to select a new rendering device or display mode
+      <Alt+Enter> Toggles between fullscreen and windowed modes
+      <Esc>       Exits the app.
+
+
+Programming Notes
+=================
+   Without Direct3D's support, point sprites can be implemented with four
+   vertices, that are oriented each frame towards the eyepoint (much like a
+   billboard). With Direct3D, though, you can refer to each point sprite by
+   just it's center position and a radius. This saves heavily on processor
+   computation time and on bandwidth uploading vertex information to the
+   graphics card.
+
+   In this sample, a particle system is implemented using point sprites. Each
+   particle is actually implemented using multiple alpha-blended point sprites,
+   giving the particle a motion-blur effect.
+
+   This sample makes use of common DirectX code (consisting of helper functions,
+   etc.) that is shared with other samples on the DirectX SDK. All common
+   headers and source code can be found in the following directory:
