Apply brightmaps to translucent and translated columns

[JNechaevsky]

Same idea and aproach as in fabiangreffrath/woof#1340. No new functions, just extended current ones to draw brightmapped pixels. Few remarks:

• For Doom we deffinitly needed, and it's easy to test with a testing map from Woof's PR. There is not translucent walls in original Specifics, it's a Boom-ism. Small expection was made long time ago for scrolling texture right, AFAIR, just as small possible nicification for NOVA.wad.
• For Heretic we probably need it. Testing translucent columns was easy, just set MF_SHADOW flag to Phoenix Rod, but testing translucent+translated columns - no idea how. Neigher I am able to run HeHacked, this is what always happening with 1.3 version for DOS (screenshot).
• For Hexen we most likely need it. Probably ACS allows to set mobj flags? Aside from that, mobj flags MF_SHADOW and MF_ALTSHADOW were used for testing translucent columns. Translucent+translated columns are the same dilemma as in Heretic.
• For Strife we don't need it, as there is no Crispy brightmaps, and Strife using own aproach with COLORMAP trick.

Thanks again!

My pleasure! Looks likes all small things are done for Crispy for now, and it's time to take care about Woof.
I'll explain very shortly, as it's wrong place to do it here. Basically, it's smooth lines for ZDoom color scheme. Until smoothing everything is fine:

With smoothing lines, however, this happens:

See that bright lines are going "too dark while smoothing", and dark brown lines are no longer neat. Bright lines can be fixed by reducing steps to +1 here: https://github.com/fabiangreffrath/woof/blob/master/src/am_map.c#L650-L651, but this is not optimal, does not fix dark brown lines and will break neat smoothing on overlay mode.

Okay, enough for now. It's a visual part, and I always treat the visual things with great trepidation, but I hate to complain without suggesting any solutions, so I'll have to investigate.
