Window Types
#include <Windows.h>
These are the standard window types supported by the Window Manager
and the constants used to refer to them:
dBoxProc=1 plainDBox=2 altDBoxProc=3 rDocProc=16 (et.al)
documentProc=0 noGrowDocProc=4 zoomDocProc=8 zoomNoGrow=12

Notes: Use NewWindow to create the desired type of window, or create a 'WIND'
resource and call GetNewWindow. It is possible to create your own window
definition routine.
The “grow icon” seen in documentProc and zoomDocProc windows includes the
horizontal and vertical scrollbar delimiter lines. Note that neither the grow
icon nor these lines are drawn until you call DrawGrowIcon.
The rDocProc window is actually a family of window types allowing you to
specify the curvature of the rounded-corner rectangle which defines its
structure region:
Window types are also referred to as variant codes. The variant code allows a
single window definition function ('WDEF') to implement several related types
of windows as "variations on a theme". For example, the dBoxProc type of
window is a variation of the standard document window; both use the window
definition function whose resource ID is 0, but the document window has a
variation code of 0 while the dBoxProc window has a variation code of 1.
