Subject: [PATCH] Decompile 3 functions in
 Source/Contents/Effects/RotateLineEffect.cpp,
 Source/Contents/Effects/RotateLineEffect.h

Batch #4067 by Yommy: 1 byte-identical, 2 confirmed by peer review.

- fn_19155 CRotateLineEffect::Close: logic confirmed by peer review
- fn_19156 CRotateLineEffect::Slot01: logic confirmed by peer review
- fn_19157 CRotateLineEffect::Slot06: byte-identical

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