effect: Add DeformEffect DeformEffect is an abstract class that should be used to write effects that change the geometry of an actor before submitting it to the GPU. Just like the ShaderEffect class, DeformEffect renders the actor to which it has been applied into an FBO; then it creates a mesh and stores it inside a VBO. Sub-classes can control vertex attributes like position, texel coordinates and the color.

Move header inclusion guard at the top GCC has some optimization for the inclusion guard, but they only work if the check is the outermost one. We're fairly inconsistent because of historical reasons, so we should ensure that we follow the same pattern in every public header.
