extern "C" {
Fixed a few win32 keyboard/mouse problems. First, the mouse hook now captures non-client area mouse messages. Previously, these were ignored (because i forgot about them) and they caused all kinds of problems because they weren't forwarded. For example, clicking on a window border would cause the window to start resizing when the mouse came back to the server screen. Moving inside a title bar meant that the mouse wouldn't move on the client screen. Second, because non-client messages are now handled, the full screen transparent window is no longer necessary to capture input so it's never displayed. (The window is still necessary for clipboard ownership so it's still created.) No transparent window means no screen flashing. It also means we don't have to become the foreground and active window. This plays better with apps that minimize or restore when they're no longer the foreground application/active window. Third, fixed the low level keyboard hook to forward toggle key updates, which it was neglecting to do. Finally, keyboard and mouse input is always forwarded from the hook to the primary screen handler which then shadows the current key and mouse button state. If we're using low level hooks then this isn't really necessary and GetKeyState() always returns the right info but without low level hooks it means we can just use the shadow state. It also means we don't have to show our window in order to get the system's key state table up to date, fixing the screen flash when checking for the scroll lock state.
