Make _ScreenCapture_CaptureWnd convert HWnd

[NerdFencer]

The code in _ScreenCapture_CaptureWnd (from ScreenCapture.au3) can capture window controls as well as windows, but this is not apparent because it is not mentioned and fails if passed the raw handle returned by a GUICtrlCrate function.
This can easily be fixed by modifying one line of the header, and adding another to the function.
line 100:
; Description ...: Captures a screen shot of a specified window
Change to:
; Description ...: Captures a screen shot of a specified window or control

Insert before line 125:
If Not(IsHWnd($hWnd)) Then $hWnd=GUICtrlGetHandle($hWnd)

Before:

Local $tRect = _WinAPI_GetWindowRect($hWnd)

After:

If Not(IsHWnd($hWnd)) Then $hWnd=GUICtrlGetHandle($hWnd)
Local $tRect = _WinAPI_GetWindowRect($hWnd)

This simple change makes the function fail less easily, and makes its full ability more apparent.
