When you load an image and bind it as a texture I can delete the loaded image data and the texture still works. This means that the texture data is either copied to VRAM or another copy is made in System RAM. Am I wrong? If I don''t delete the loaded data, will my app eat 2x as much memory? So is it correct to do: Load() glTexImage2D(...) delete [] image->data and then use the texture?
