NAME
    max - returns the maximum of two scalars or each respective component of
    two vectors

SYNPOSIS
      float  max(float  a, float  b);
      float1 max(float1 a, float1 b);
      float2 max(float2 a, float2 b);
      float3 max(float3 a, float3 b);
      float4 max(float4 a, float4 b);
 
      half   max(half  a, half  b);
      half1  max(half1 a, half1 b);
      half2  max(half2 a, half2 b);
      half3  max(half3 a, half3 b);
      half4  max(half4 a, half4 b);
 
      fixed  max(fixed  a, fixed  b);
      fixed1 max(fixed1 a, fixed1 b);
      fixed2 max(fixed2 a, fixed2 b);
      fixed3 max(fixed3 a, fixed3 b);
      fixed4 max(fixed4 a, fixed4 b);

PARAMETERS
    a       Scalar or vector.

    b       Scalar or vector.

DESCRIPTION
    Returns the maximum of two same-typed scalars *a* and *b* or the
    respective components of two same-typed vectors *a* and *b*. The result
    is a three-component vector.

REFERENCE IMPLEMENTATION
    max for float3 vectors could be implemented this way:

      float3 max(float3 a, float3 b)
      {
        return float3(a.x > b.x ? a.x : b.x, 
                      a.y > b.y ? a.y : b.y, 
                      a.z > b.z ? a.z : b.z);
      }

PROFILE SUPPORT
    max is supported in all profiles. max is implemented as a compiler
    built-in.

    Support in the fp20 is limited.
