+Description
+===========
+   The StencilMirror sample uses stencil buffers to implement a mirror effect.
+   In the sample, a watery terrain scene is rendered with the water reflecting
+   a helicopter that flies above.
+
+   Stencil buffers are a depth buffer technique that can be updated as
+   geometry is rendered, and used again as a mask for drawing more geometry.
+   Common effects include mirrors, shadows (an advanced technique), dissolves,
+   etc..
+
+   Note that not all cards support all features for all the various stencil
+   buffer techniques (some hardware has no, or limited, stencil buffer
+   support). For more information on stencil buffers, 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
+=================
+   In this sample, a stencil buffer is used to create the effect of a 
+   reflection coming off the water. The geometry of the water is rendered into
+   the stencil buffer. Then, the stencil buffer is used as a mask to render the
+   scene again, this time with the geometry translated and rendered upside
+   down, to appear as if it was reflected in the mirror.
+
+   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:
