visual\viewport indicator for vrayLight directional amount

[gimiky]

i searched and could not find any requests for this yet (sorry if it's a duplicate).. the new directional option on vraylights is awesome, but can be pretty hard to tell exactly where the light will be falling without test rendering--especially in animated scenes. it would be really handy to have a viewport indicator for the spread of the light--similar to the "hotspot" and "falloff" controls on a standard max spotlight. obviously the area of the light affects this, but i imagine there'd be some way to estimate this?

thanks,
greg
