Intrinsic for applying a color matrix to allocations.
If the element type is UNSIGNED_8,
it is converted to FLOAT_32 and
normalized from (0-255) to (0-1). If the incoming vector size
is less than four, a F32_4(RenderScript) is created by
filling the missing vector channels with zero. This value is
then multiplied by the 4x4 color matrix as performed by
rsMatrixMultiply(), adding a F32_4(RenderScript), and then
writing it to the output Allocation.
If the ouptut type is unsigned, the value is normalized from
(0-1) to (0-255) and converted. If the output vector size is
less than four, the unused channels are discarded.
Supported elements types are U8(RenderScript), U8_2(RenderScript), U8_3(RenderScript), U8_4(RenderScript),
F32(RenderScript), F32_2(RenderScript), F32_3(RenderScript), and F32_4(RenderScript).

| e | Element type for inputs and outputs, As of API 19, this parameter is ignored. The Element type check is performed in the kernel launch. |
Invoke the kernel and apply the matrix to each cell of input
Allocation and copy to the output Allocation.
If the vector size of the input is less than four, the
remaining components are treated as zero for the matrix
multiply.
If the output vector size is less than four, the unused
vector components are discarded.
