Ok, thank you Anton.

I'll wait for your patch.

Bye

> the set of possible argument lists for which all arguments have the same
> element type as the result vector, and the total number of elements is equal

> (float4)( float2, float, float )
> (float4)( float, float2, float )
> (float4)( float, float, float2 )
> (float4)( float2, float2 )
> (float4)( float3, float )
> (float4)( float, float3 )
> (float4)( float )"
