Description
The PixelGetColor function with passed HWND parameter should analyze a DC of the specified window. Now it still analyze a entire screen DC instead.
Probably, the issue is passing NULL to GetDC function always. As I understand the GetDC function call is a part of the PixelGetColor implementation.
This is a log of WinAPI functions that have been called by PixelGetColor function work in an attachment.

Perhaps, this bug causes a strange behavior of the PixelCoordMode option switching. Now it seems that the default (absolute screen coordinates) mode is used always.

HWND used only if "PixelCoordMode" 0 or 2. If 1 then HWND is ignored. So it was always.

I have checked a behavior with "PixelCoordMode" option equal to 2. GetDC WinAPI function that is called before GetPixel still receive a NULL as input parameter.
It is strange why processing of the HWND parameter should be tied with "PixelCoordMode" option. Expected result of the passing HWND parameter is possibility of getting a pixel color from an overlapped window.
