+/// Sets the size limits of the specified window's content area.
+///
+/// This function sets the size limits of the content area of the specified 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.
+///
+/// The size limits are applied immediately to a windowed mode window and may cause it to be resized.
+///
+/// The maximum dimensions must be greater than or equal to the minimum dimensions. glfw.dont_care
+/// may be used for any width/height parameter.
+///
+/// Possible errors include glfw.Error.NotInitialized, glfw.Error.InvalidValue and glfw.Error.PlatformError.
+///
+/// If you set size limits and an aspect ratio that conflict, the results are undefined.
+///
+/// wayland: The size limits will not be applied until the window is actually resized, either by
+/// the user or by the compositor.
+///
+/// @thread_safety This function must only be called from the main thread.
