Routine Description:

    This function takes a bitmap that needs to be displayed and stretches it 
    using GDI. Once the bitmap is stretched to the required dimentions we display
    it using BitBlt. We have to do this decause some buggy video drivers and or
    hardware hang on using StretchBlt.
    Or the StretchBlt would generate a corupted bitmap.

Arguments:

    hdcDest         destination device-context handle    
    nXOriginDest    x-coordinate of origin of destination rectangle    
    nYOriginDest    y-coordinate of origin of destination rectangle    
    nWidthDest      width of destination rectangle    
    nHeightDest     height of destination rectangle    
    hdcSrc          source device-context handle    
    nXOriginSrc     x-coordinate of origin of source rectangle    
    nYOriginSrc     y-coordinate of origin of source rectangle    
    nWidthSrc       width of source rectangle    
    nHeightSrc      height of source rectangle    
    fdwRop          raster operation

Return value:

    TRUE == SUCCESS
