Function: RawImage_FromDevice
Params: ADC:

Returns:
This function is utilized when the function TBitmap.LoadFromDevice is called
The main use for this function is to get a screenshot. It may have other uses,
but this is the only one implemented here.
MWE: exept for the desktop, there is always a bitmep selected in the DC.
So get this internal bitmap and pass it to RawImage_FromBitmap
