 * Renderscript is a high-performance runtime that provides graphics rendering and

 * compute operations at the native level. Renderscript code is compiled on devices

 * at runtime to allow platform-independence as well.

 * This reference documentation describes the Renderscript runtime APIs, which you

 * can utilize to write Renderscript code in C99. The Renderscript header

 * files are automatically included for you, except for the rs_graphics.rsh header. If

 * you are doing graphics rendering, include the graphics header file like this:

 *

 * <code>#include "rs_graphics.rsh"</code>

 *

 * To use Renderscript, you need to utilize the Renderscript runtime APIs documented here

 * as well as the Android framework APIs for Renderscript.

 * For documentation on the Android framework APIs, see the <a href=

 * "http://developer.android.com/reference/android/renderscript/package-summary.html">

 * android.renderscript</a> package reference.

 * For more information on how to develop with Renderscript and how the runtime and

 * Android framework APIs interact, see the <a href=

 * "http://developer.android.com/guide/topics/renderscript/index.html">Renderscript

 * developer guide</a> and the <a href=

 * "http://developer.android.com/resources/samples/RenderScript/index.html">

 * Renderscript samples</a>.
