Subject: [PATCH] Decompile 4 functions in
 Source/Contents/Effects/RedLineEffect.cpp,
 Source/Contents/Effects/RedLineEffect.h

Batch #4730 by eAthena: 3 byte-identical, 1 confirmed by peer review.

- fn_19134 CRedLineEffect::CreateLines: logic confirmed by peer review
- fn_19135 CRedLineEffect::Close: byte-identical
- fn_19136 CRedLineEffect::Slot01: byte-identical
- fn_19137 CRedLineEffect::Slot06: byte-identical

Peer-reviewed-by: youko, Millenium
Accepted without human review: peers confirmed the logic ("same" ahead by at least 3, with 70% of the votes).
