NAME: CONTROL_WINDOW
SYNOPSIS: Control window class
INTERFACE:
CONTROL_WINDOW() - constructor.
QueryCid() - return the CID private member.
ClaimFocus() - focus the current window
QueryFont() - return the current font handle
SetFont() - sets the current font, optionally redrawing
the control. Takes either a font handle or
a logical font object
SetControlValueFocus()
Redefines the CONTROL_VALUE::SetControlValueFocus to simply call
ClaimFocus.
Validate() - checks the control's contents for validity.
IndicateError() - indicates erroneous user input
PARENT: WINDOW, CONTROL_VALUE, FORWARDING_BASE
USES: CID, FONT
NOTES:
At its construction, each control checks its owning window
(to which it forwards all error reports and queries) to see
if it failed.

SYNOPSIS: Simple wrapper for creating a scrollbar control

SetPos() - set position within scrolling
SetRange() - set range of values

NOTES:
It would be interesting to make a version of this control
which adopts the embedded scrollbar of another control, e.g.
that of a MLE.
The SetXxx member functions do not redraw the control.
