/**
* <p>
* Memory allocation class for renderscript. An allocation combines a
* {@link android.renderscript.Type} with the memory to provide storage for user data and objects.
* This implies that all memory in Renderscript is typed.
* </p>
*
* <p>Allocations are the primary way data moves into and out of scripts. Memory is user
* synchronized and it's possible for allocations to exist in multiple memory spaces
* concurrently. Currently those spaces are:</p>
* <ul>
* <li>Script: accessable by RS scripts.</li>
* <li>Graphics Texture: accessable as a graphics texture.</li>
* <li>Graphics Vertex: accessable as graphical vertex data.</li>
* <li>Graphics Constants: Accessable as constants in user shaders</li>
* </ul>
* </p>
* <p>
* For example, when creating a allocation for a texture, the user can
* specify its memory spaces as both script and textures. This means that it can both
* be used as script binding and as a GPU texture for rendering. To maintain
* synchronization if a script modifies an allocation used by other targets it must
* call a synchronizing function to push the updates to the memory, otherwise the results
* are undefined.
* </p>
* <p>By default, Android system side updates are always applied to the script accessable
* memory. If this is not present, they are then applied to the various HW
* memory types. A {@link android.renderscript.Allocation#syncAll syncAll()}
* call is necessary after the script data is updated to
* keep the other memory spaces in sync.</p>
*
* <p>Allocation data is uploaded in one of two primary ways. For simple
* arrays there are copyFrom() functions that take an array from the control code and
* copy it to the slave memory store. Both type checked and unchecked copies are provided.
* The unchecked variants exist to allow apps to copy over arrays of structures from a
* control language that does not support structures.</p>
*
