Download MSVC compiler/linker & Windows SDK without installing full Visual Studio

This downloads standalone 64-bit MSVC compiler, linker & other tools, also headers/libraries from Windows SDK into portable folder, without installing Visual Studio. Has bare minimum components - no UWP/Store/WindowsRT stuff, just files & tools for 64-bit native desktop app development.

Run python.exe and it will download output into msvc folder. By default it will download latest available MSVC & Windows SDK - currently v14.32.17.2 and v10.0.22621.0.

You can list available versions with python.exe --show-versions and then pass versions you want with --msvc-version and --sdk-version arguments.

To use cl.exe/link.exe from output folder, first run setup.bat - after that PATH/INCLUDE/LIB env variables will be setup to use all the tools as usual. You can also use clang-cl.exe with these includes & libraries.

To use clang-cl.exe without running setup.bat, pass extra /winsysroot msvc argument (msvc is folder name where output is stored).

This document records my conclusions of experimenting Firefox 68 and Chromium 74 font fallback mechanism on Windows, as dated of the writing time.

Definition of font fallback

Both Firefox and Chromium allow users to configure the desired fonts used for displaying HTML in various languages. The HTML language is specified in the <html lang={lang}> tag. For instance, a Chinese webpage could be written as <html lang="zh"> or more specifically <html lang="zh-CN">. English webpage is <html lang="en"> or simplify lefting out the lang tag (although strongly discouraged by the W3C standard). The per-script font setting in Chromium is unlocked with the Advanced Font Settings extension.

When the webpage specify the font list to be used for certain element in CSS, the browsers will first search its font cache for
