Emergency Light Feature

[Zeneric09]

Siren feature (improved vanilla siren) for GTA SA.

Vanilla GTA SA uses 2dfx for siren, that's it. It doesn't light texture up (like GTA SA's vehiclelight function that lights up the vehiclelight texture at night time).

Need to be able to light up the siren texture (And flash it).
imvehft + emergency light mod does this too but it uses two textures to switch between (non lighted up texture and lighted up texture - like vehiclelight and vehiclelight_on) - needs to be one texture and let script, configurable via ini or something, control brightness (for optimization sake).

Need to be able to add siren 2dfx with dummies/nodes (cannot do that with vanilla gta sa, is hard coded), up to 99 siren dummies/nodes maybe.

Need to be able to control siren lighting/color/shadow size/corona size/switching time/etc, both 2dfx and texture syncing together.

See picture of imvehft + emergency light mod configuration example on ambulance (id 416):
