- changed DrawTexture so that the parameters get parsed in the varargs function directly and that the virtual function that is getting called gets the fully prepared data.

Browse source 
In order to avoid passing around tag lists, DrawTextV needs to parse everything itself and then pass a fully initialized structure to DrawTexture. This cannot be done if all variants require a varargs tag list.
Apparently the only reason for the old approach was the 'hw' parameter which was never used.
