This change avoids inadvertent capture of certain system windows (e.g. the Start menu, other taskbar menus, and notification toasts) when capturing a specific window on Windows. It stops using EnumWindows for detection of overlapping windows, because this API excludes these system windows from its enumeration. Using FindWindowEx instead enumerates these windows. The enumeration logic is refactored somewhat because a callback is no longer necessary.
