I have added new function IsVolumetricShadowsEnabled()

[TracerDS]

Do you have any void type lua functions? How would that work here?

[Xenius97]

Resolves #2777 too, or is this a different shadow-type?

it should be "areVolumetricShadowsEnabled", not "isVolumetricShadowsEnabled" since "shadows" is a plural noun ;), now, i may think that this function accept "Element" at first argument, but it doesn't.

could be are but are rarely used, but is looks way familiar, I do not know really if that worth change it also there is no such thing as disabled shadows per element. @CrosRoad95
