gr_corona Implentation

I see that there is a command called "gr_corona" for SRB2's OpenGL mode. I don't plan on using coronas, but I'm curious on how you can create them.

There doesn't appear to be any documentation on them on the Wiki, but I know they must exist in some form, because of the command and this part of the source: https://github.com/STJr/SRB2/blob/master/src/hardware/hw_light.h

They're commented out in the source code. Go into src/hardware and open hw_light.h, then add #define ALAM_LIGHTING and compile to enable them.

Or alternatively, you can use my build:
https://www.dropbox.com/s/o2mgumrvl34q7fl/srb2coronas.exe
https://www.dropbox.com/s/tpj9zrifrt5ihvg/r_opengl.dll

Ah. Well, they're not worth it if they require another .exe, but whatever.

Thanks!
