The short guide about branding and logo usages
(from /Telegram/Resources/art) in Kepka:
1. logo_256.png/logo_256_no_margin.png -
used in /Telegram/SourceFiles/window/main_window.cpp for loading logo
(nowrap logo is used on Mac), in /Telegram/SourceFiles/messenger.[cpp|h],
in /Telegram/SourceFiles/platform/linux/specific_linux.cpp and in qrc.
Required for branding;
2. icon64.png - Doxyfile and MacOS image assets (they are duplicated in
/Telegram/Telegram/Images.xcassets/[Icon.iconset|AppIcon.appiconset);
3. icon[<resolution>[@x2]].png - MacOS image assets. We will update
these icons in next commit;
4. favicon.ico - seems unused;
5. icon256.ico - Windows Resource for EXE;
There is also a dangling reference inside
/Telegram/Resources/uwp/AppX/AppxManifest.xml. It shoud be fixed in some
of next commits.
