Train Sim World 4 - Improved signal visuals

Hey guys. This mod dramatically improves the look and behaviour of the signals and its flares in TSW, but especially so for new TSW 4 British routes.

Nonetheless, this will benefit ALL TSW routes. The details of what routes are benefited from it and how it affects then is listed below:

TSW 5 and 4 British routes ONLY

• Brand new high-resolution signal textures
• Brand new signal emissive visuals (brighter looking light source coming from the signals)
• Brand new signal emissive colours (more colour accurate reds, yellows and greens)
• Brand new lens flare visuals (much more realistic looking, with the old low-resolution variant replaced)
• Brand new lens flare brightness (much brighter from a distance, especially so at night)
• Significantly increased lens flare render distance, especially so at night (lens flares can now be seen from MUCH further away)
• New lens flare behaviour (the flare size responds to the distance away from it in a much more realistic way. It no longer 'grows' unrealistically)

ALL other TSW routes, even older ones

• Brand new lens flare visuals (much more realistic looking, with the old low-resolution variant replaced)
• Brand new lens flare brightness (much brighter from a distance, especially so at night)
• Significantly increased lens flare render distance, especially so at night (lens flares can now be seen from MUCH further away)
• New lens flare behaviour (the flare size responds to the distance away from it in a much more realistic way. It no longer 'grows' unrealistically)
