/*! @brief Sets the size limits of the specified window.
*
* This function sets the size limits of the client area of the specified
* window. If the window is full screen, the size limits only take effect if
* window. If the window is full screen, the size limits only take effect
* once it is made windowed. If the window is not resizable, this function
* does nothing.
