OS X doesn't have the same concept of maximized windows as Windows does. There's no mode that prevents a normally-resizable window from being resized. If a window is "zoomed", it mostly fills the screen but the user can still move or resize it, at which point it ceases to be in the zoomed state. So, users are confused and frustrated when they can't resize a window that's maximized. To get similar behavior while still respecting Win32 semantics, we now let the user try to resize maximized windows. (The resize cursors are shown at the edges of the window frame.) When they start, a request is submitted to the app to restore the window. Unless and until the window is restored, we don't actually allow the window to change its size. The user expects to resize the window from its current (maximized) position. It should not jump to its normal position upon being restored. So, we set the window's normal position to its current position before restoring it.
