-You can do scaling if you are getting sprites from a texture with SDL_RenderCopy() but i cannot guarantee you antialiasing.
-
-With function SDL_RenderCopy() you pass 4 params:
-
-    a pointer to a renderer (where you are going to renderize).
-    a pointer to a texture (where you are going to get the sprite).
-    pointer to source rect(the area and position where you get the sprite on the texture).
-    and pointer to dest rect(the area and position on the renderer you are going to draw).
-
-You should only modify your dest rect like for example, if you are going to render an image 300 x 300 and you want it scaled, your dest rect should be like 150 x 150 or 72 x 72 or whatever value you wanted to scale.
