No bitwise OR, select ONE method only.

No default value. Client should choose one as default.

Different applications use different rendering methods, there is no universal solution.

Note: FramePool and PrintWindow support pseudo-minimize — when the target window is minimized, they make it transparent and click-through, then restore it without activation, allowing screencap to continue without disturbing the user.

Other screencap methods will fail when the target window is minimized.
