This methods locks the surface to allow direct access to the pixels using the

locking, you still need to call this method to enable the set/get pixel
methods. You should unlock the surface when you're doing modifying it.
- Note
Calling this method multiple times means that you need to call
unlock an equal number of times for the surface to become unlocked.
