Re: [GD-Windows] Out of window mouse up messages

SetCapture() is the correct way to handle mouse drag (press button, move
mouse around, release button) functionality. It's important to handle
WM_CAPTURELOST as well. SetCapture() is appropriate here because it's a
temporary state.

SetCapture() is NOT the correct way to receive all mouse input even if the
mouse is outside the window, because this is not temporary. In fact,
receiving mouse input when the mouse is outside the window should be done
only in drag situations (but I know this is not always possible).
