       bool SDL_SetTextureAlphaMod(SDL_Texture *texture, Uint8 alpha);

DESCRIPTION

       When  this  texture  is  rendered,  during the copy operation the source alpha value is modulated by this
       alpha value according to the following formula: srcA=srcA*(alpha/255)  Alpha  modulation  is  not  always
       supported by the renderer; it will return false if alpha modulation is not supported.
