void Graphics::drawBufferedLine( int16_t x , int16_t y , int16_t* buffer , uint16_t w , Image& img )
Graphics::drawBufferedLine will render the buffered line onto the specified graphics object. The class inheriting from Graphics will have to implement this. Whoever is calling this has to make sure that the buffer is set correctly (rgb565 vs indexed).
If you are using this in your game you are probably doing something wrong!
