Simple Shadows from PrBroom+

[Async-Unicorn]

Duplicated from Doomworld thread as requested, =)

"Is there any way to implement these OpenGL "Simple Shadows" from PrBoom+?

I loved them very much and it would be nice to see their return...

Though I don't know honestly if they're compatible with "Indexed Lighting" mode (there should be a reason why they were removed apart from the menu rewrite, I suppose), but maybe they can be adapted? "

A bit of an update on this... I have tested simply migrating the feature over from before DSDA-Doom cut them... But I think the main reason it was cut was due to it not being compatible via the "Indexed renderer".

I'll keep this issue open, but it'll take a whole new implementation to get the shadows working under "Indexed". In a way I sorta see this as a good thing, as if I were to add this feature back, I'd also like to have something that was software compatible.
