Improves SpriteTest.
It is easier to see if Sprite works as SpriteBatchNode (and vice-versa).
Needed for the new renderer.
Also adds `const` to title() and subtitle()
- Adds `CC_REQUIRES_NULL_TERMINATION` to methods that require a NULL at the end
- Removes more Hungarian notations in samples
- s/sprite/scene: fix from previous commit
- `CCLog` -> `log`
- `getLayerNamed` -> `getLayer`
- `getPropertyNamed` -> `getProperty`
- and other small fixes
Handy macros for callbacks.
Instead of:
std::bind(func_ptr, instnace, std::placeholder::_1)
you use:
CALLBACK_1(func_ptr, instance)
And also removes more warnings from the tests
Base class displays the Menu( <- O -> )
Improved in some tests the way to create entries.
Instead of defining the tests twice: the "create" method, and the entry
in the array, it is only needed in the array (ActionsTest, SpriteTest
and Texture2DTest)
