22VCL positioning
23
24Window coordinates are parent relative, with exception of maState fields, they
25have screen coordinates.
26
27Every window has a parent window, usually the client area of an existing window,
28otherwise the desktop window.
29
30When a window is to be sized/moved, SetPosSize is called.
31Since coordinates are the position/size of client area, we need to calculate
32current window frame size/position and map to screen coordinates using the
33owner window position as offset.
