// $Id$
//JVK
// On 2D panels all instruments include light sources were in night displayed
// with a red mask (instrument light). It is not correct for light sources
// (bulbs). There is added new layer property "emissive" (boolean) (only for
// textured layers).
// If a layer has to shine set it in the "instrument_def_file.xml" inside the
// <layer> tag by adding <emissive>true</emissive> tag. When omitted the default
// value is for backward compatibility set to false.
