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

SYNOPSIS
      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.
