*
* 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 target="_parent" 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 target="_parent" href=
* "http://developer.android.com/guide/topics/renderscript/index.html">Renderscript
* developer guide</a> and the <a target="_parent" href=
* "http://developer.android.com/resources/samples/RenderScript/index.html">
