* rs_value_types.rsh: Numerical Types
*
* Scalars:
*
* RenderScript supports the following scalar numerical types:
*
* 8 bits 16 bits 32 bits 64 bits
* Integer: char, int8_t short, int16_t int32_t long, long long, int64_t
* Unsigned integer: uchar, uint8_t ushort, uint16_t uint, uint32_t ulong, uint64_t
* Floating point: half float double
*
*
* Vectors:
*
* RenderScript supports fixed size vectors of length 2, 3, and 4.
* Vectors are declared using the common type name followed by a 2, 3, or 4.
* E.g. float4, int3, double2, ulong4.
*
* To create vector literals, use the vector type followed by the values enclosed
* between curly braces, e.g. (float3){1.0f, 2.0f, 3.0f}.
*
* Entries of a vector can be accessed using different naming styles.
*
* Single entries can be accessed by following the variable name with a dot and:
* - The letters x, y, z, and w,
* - The letters r, g, b, and a,
* - The letter s or S, followed by a zero based index.
*
* For example, with int4 myVar; the following are equivalent:
* myVar.x == myVar.r == myVar.s0 == myVar.S0
* myVar.y == myVar.g == myVar.s1 == myVar.S1
* myVar.z == myVar.b == myVar.s2 == myVar.S2
* myVar.w == myVar.a == myVar.s3 == myVar.S3
*
* Multiple entries of a vector can be accessed at once by using an identifier that is
* the concatenation of multiple letters or indices. The resulting vector has a size
* equal to the number of entries named.
*
* With the example above, the middle two entries can be accessed using
* myVar.yz, myVar.gb, myVar.s12, and myVar.S12.
*
* The entries don't have to be contiguous or in increasing order. Entries can even be
* repeated, as long as we're not trying to assign to it. You also can't mix the naming
* styles.
*
* Here are examples of what can or can't be done:
* float4 v4;
* float3 v3;
* float2 v2;
* v2 = v4.xx; // Valid
* v3 = v4.zxw; // Valid
* v3 = v4.bba; // Valid
* v3 = v4.s032; // Valid
* v3.s120 = v4.S233; // Valid
* v4.yz = v3.rg; // Valid
* v4.yzx = v3.rg; // Invalid: mismatched sizes
* v4.yzz = v3; // Invalid: z appears twice in an assignment
* v3 = v3.xas0; // Invalid: can't mix xyzw with rgba nor s0...
* v3 = v4.s034; // Invalid: the digit can only be 0, 1, 2, or 3
*
*
* Matrices and Quaternions:
*
* RenderScript supports fixed size square matrices of floats of size 2x2, 3x3, and 4x4.
* The types are named rs_matrix2x2, rs_matrix3x3, and rs_matrix4x4. See
* Matrix Functions for the list of operations.
*
* Quaternions are also supported via rs_quaternion. See Quaterion Functions for the list
* of operations.
