Subject: [PATCH] Decompile 3 functions in Source/UI/Text/UIStaticText.cpp

Batch #12172 by cremane: 0 byte-identical, 3 confirmed by peer review.

- fn_10966 UIStaticText::SetTextFittedCodePage: logic confirmed by peer review
- fn_10820 UIStaticText::Paint: logic confirmed by peer review
- fn_10962 UIBmpTextButton::AddTextStyle: logic confirmed by peer review

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