/*
 * convert: Convert numerical vectors
 *
 * Converts a vector from one numerical type to another.  The conversion are done entry per entry.
 *
 * E.g calling a = convert_short3(b); is equivalent to doing
 * a.x = (short)b.x; a.y = (short)b.y; a.z = (short)b.z;.
 *
 * Converting floating point values to integer types truncates.
 *
 * Converting numbers too large to fit the destination type yields undefined results.
 * For example, converting a float that contains 1.0e18 to a short is undefined.
 * Use clamp() to avoid this.

/*
 * rsPackColorTo8888: Create a uchar4 RGBA from floats
 *
 * Packs three or four floating point RGBA values into a uchar4.
 *
 * The input values are typically between 0.0f and 1.0f inclusive.  For input values outside
 * of this range, the resulting outputs will be clamped to be between 0 and 255.  As this
 * clamping may be done after the input is multiplied by 255.f and converted to an integer,
 * input numbers greater than INT_MAX/255.f or less than INT_MIN/255.f result in
 * undefined behavior.
 *
 * If the alpha component is not specified, it is assumed to be 1.0, i.e. the result will
 * have an alpha set to 255.
 *
 * Parameters:
 *   r: Red component.
 *   g: Green component.
 *   b: Blue component.
 *   a: Alpha component.
 *   color: Vector of 3 or 4 floats containing the R, G, B, and A values.
