/**
* <p> This class provides the primary method through which data is passed to
* and from RenderScript kernels. An Allocation provides the backing store for
* a given {@link android.renderscript.Type}. </p>
*
* <p>An Allocation also contains a set of usage flags that denote how the
* Allocation could be used. For example, an Allocation may have usage flags
* specifying that it can be used from a script as well as input to a {@link
* android.renderscript.Sampler}. A developer must synchronize across these
* different usages using {@link android.renderscript.Allocation#syncAll} in
* order to ensure that different users of the Allocation have a consistent view
* of memory. For example, in the case where an Allocation is used as the output
* of one kernel and as Sampler input in a later kernel, a developer must call
* {@link #syncAll syncAll(Allocation.USAGE_SCRIPT)} prior to launching the
* second kernel to ensure correctness.
*
* <p>An Allocation can be populated with the {@link #copyFrom} routines. For
* more complex Element types, the {@link #copyFromUnchecked} methods can be
* used to copy from byte arrays or similar constructs.</p>

* Only applies to an Allocation whose Element is a vector of length 3 (such as
* {@link Element#U8_3} or {@link Element#RGB_888}). Enabling this feature may make
* copying data from the Allocation to an array or vice-versa less efficient.
*
* <p> Vec3 Element cells are stored in an Allocation as Vec4 Element cells with
* the same {@link android.renderscript.Element.DataType}, with the fourth vector
* component treated as padding. When this feature is enabled, only the data components,
* i.e. the first 3 vector components of each cell, will be mapped between the array
* and the Allocation. When disabled, explicit mapping of the padding components
* is required, as described in the following example.
*
* <p> For example, when copying an integer array to an Allocation of two {@link
* Element#I32_3} cells using {@link #copyFrom(int[])}:
* <p> When disabled:
* The array must have at least 8 integers, with the first 4 integers copied
* to the first cell of the Allocation, and the next 4 integers copied to
* the second cell. The 4th and 8th integers are mapped as the padding components.
*
* <p> When enabled:
* The array just needs to have at least 6 integers, with the first 3 integers
* copied to the the first cell as data components, and the next 3 copied to
* the second cell. There is no mapping for the padding components.
*
* <p> Similarly, when copying a byte array to an Allocation of two {@link
* Element#I32_3} cells, using {@link #copyFromUnchecked(int[])}:
* <p> When disabled:
* The array must have at least 32 bytes, with the first 16 bytes copied
* to the first cell of the Allocation, and the next 16 bytes copied to
* the second cell. The 13th-16th and 29th-32nd bytes are mapped as padding
* components.
*
* <p> When enabled:
* The array just needs to have at least 24 bytes, with the first 12 bytes copied
* to the first cell of the Allocation, and the next 12 bytes copied to
* the second cell. There is no mapping for the padding components.
*
* <p> Similar to copying data to an Allocation from an array, when copying data from an
* Allocation to an array, the padding components for Vec3 Element cells will not be
* copied/mapped to the array if AutoPadding is enabled.
*
* <p> Default: Disabled.
