So, when I have an application, that uses a background image (which is the
origincal background for my question), the appropriate way to "redraw" a
text would be:

- calculate the surface of a text one wants to draw
- store this specific piece of the old surface somewhere
- draw the text

now, when redrawing the text:
- blit the old surface over the text surface
- repeat the above 3 steps for the new text

Or is it done in another way? I'm not that familiar with SDL programming,
maybe I'm just doing it wrong.

Best regards & joyeux noel,

Don't go that way: next thing user will ask is to restore what was behind
the text on the surface.
