This fixes a couple of problems in the setting of the WM_NORMAL_HINTS
window manager property.
The flags were set indicating that the width, height, x, and y fields
were valid, but these fields in fact contained garbage. Since the
fields are obsolete now (starting with X11R5), I simply removed the
code that set the corresponding flags.
Also, the base_width, base_height, width_inc, and height_inc fields
were not set. This caused the window manager to display incorrect
values for window size while resizing it.
I have sent this patch to DEC SRC.
