Make an option to disable shadows at View level.

[Borgo1971]

In my project I normally enable shadows for elevation, but in some Views I won't see them. I found I can hide shadows making Design Fills on 3D type elements, transparent with Graphic Overrides. But  shadows are even there, and are saved to file If we esport the design (for example to DWG). I guess shadows will even weigh down the drawing. So I think it could be useful to have a setting to disable at all shadows for each view, maybe in Model View Options. And while we're at it, it could be nice to have there the complete control of shadows, so we can set different sun positions and fill types for the same Elevation.
