+//! Traits for items that can be modified using a variety of matrix transformations.
+//!
+//! Items in the world may be resizable or rotateable etc. in a variety of different ways. This
+//! module contains the traits that are used to interact with such objects in a way, that ensures the
+//! item is not transformed illegaly. For example, an item may be scaleable by a factor, but that does
+//! not necessarily mean that it can be scaled by different factors in x and y direction (stretched).
+//! If need be, this module contains the different types of transformations and transformation
+//! restrictions to make these features available and restricting them reliably.
