+Abstract base class for tile image provider. Real implementations must inherit from it, assign properties and override methods.
Note to implementors: take any of the existing implementations as base. Try to store all constants within the class declaration leaving no magic values in implementation. This way all values won't be scattered between methods and will be easy to modify.
