; Parameters ....: $hWnd         -> GUI to contain scrollbars
;                  $iH_Scroll    -> Width in pixels of area to be scrolled
;                  $iV_Scroll    -> Height in pixels of area to be scrolled (default = 0)
;                  $iH_Tight     -> 1 = Adjust mean position of right edge of scrolled area to right (default = 0)
;                  $iV_Tight     -> 1 = Adjust mean position of bottom edge of scrolled area down (default = 0)
;                  $fBefore      -> True  = Scrollbars are being generated BEFORE controls
;                                   False = Scrollbars are being generated AFTER controls (default) - key scrolling possible
;                  $iRepeat      -> Number of lines/chars moved by a single cursor key press - default 0
;                  $bRegisterMsg -> True (default) = register WM_VSCROLL, WM_HSCROLL, WM_MOUSEWHEEL, WM_MOUSEHWHEEL & WM_KEYUP handlers
;                                   False = do not register handlers
; Requirement(s).: v3.3.6.0 or higher
; Return values .: Success - Returns a 4-element array (see remarks for details):
;                            [0] = Actual aperture width ; [1] = Actual aperture height]
;                            [2] = Width correction factor ; [3] = Height correction factor]
;                  Failure - Returns either 0 (UDF error) or negative integer (API error)
;                            If UDF error then @error set as follows:
;                               1 - hWnd not a valid handle
;                               2 - No scroll size parameters
;                               3 - Scrollbar creation or parameter setting failure
;                            If API error then @error and @extended as set by API error.  Return values:
;                               -1 - GetDC failure
;                               -2 - GetTextMetricsW failure
;                               -3 - GetClientRect failure
; Remarks .......; - The $fBefore parameter is needed because of the way Windows deals with scrollbars.  When the
;                    scrollbars are generated, the visible part of the scrollable GUI resizes to fit the in the
;                    remaining (smaller) client area.
;                    - If the scrollbars are generated BEFORE any controls, the UDF should be called with the
;                      $fBefore parameter set.  The new client size of the aperture window is returned so that
;                      controls can then be created using these values.
;                    - If controls have been created before the scrollbars are generated then the UDF should be
;                      called without the $fBefore parameter.  The correction factors returned can then be applied to
;                      any subsequent control positioning and sizing.  This is necessary because of the positions and
;                      sizes of existing controls will be slightly altered as the scrollbars are generated and the GUI
;                      resized.  Any controls created subsequently would therefore be slightly misplaced in relation
;                      to the existing ones unless the correction factors are used when positoning and sizing them.
;                    - If existing controls were fixed in place using GUICtrlResizing($GUI_DOCKALL) there is no need
;                      to apply the correction factors as the controls will not have moved with the GUI resizing.
;                  - If a value is set for $iRepeat then the UDF will register the WM_KEYUP message to allow scrolling
;                    with the cursor, pageup/down, home and end keys. Note that in this case any controls must be created
;                    after the GUISetState(@SW_SHOW) line or the key scrolling will not be activated
;                  - If there are existing message handlers for the WM_SIZE, WM_VSCROLL, WM_HSCROLL, WM_MOUSEWHEEL, WM_MOUSEHWHEEL & WM_KEYUP
;                    messages then $bMessageReg must be set to False and the relevant handler function(s) added to these handlers
;                    or registered separately
