Gets the colour at the specified location on the DC.
This method isn't available for ``wx.PostScriptDC`` or ``wx.MetafileDC`` nor
for any DC in wxOSX port, and simply returns ``wx.NullColour`` there.
.. note:: Setting a pixel can be done using DrawPoint().
.. note:: This method shouldn't be used with ``wx.PaintDC`` as accessing the
DC while drawing can result in unexpected results, notably in wxGTK.
