Problems with Data Types, High Severity (3)

	Change	Effect
1	Size of this class has been increased from 468 bytes to 476 bytes.	1) An object of this class can be allocated by the applications and old size will be hardcoded at the compile time. Call of any exported constructor will break the memory of neighboring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.

RenderWindow.hpp

	Change	Effect
1	Size of this class has been increased from 32 bytes to 56 bytes.	1) An object of this class can be allocated by the applications and old size will be hardcoded at the compile time. Call of any exported constructor will break the memory of neighboring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.
