SNAFU 使用教學（暫定）

這篇文章會簡單描述如何使用 SNAFU Python installer manager。

這個專案源自我對社群不懂 Windows 又愛亂教的不滿。如果有興趣讀相關故事，以及一些背後邏輯，可以參考我在碼天狗上的抱怨文。

特點

A-Frame orientation bug on Firefox Android

A-Frame no longer responds to device motion on Firefox on Android after Firefox version 53.

Cause

Kip removed Cardboard support in bug 1250244, which caused the problem. However, A-Frame orientation still works on other non-WebVR non-Cardboard mobile browsers.

Why doesn't the WebVR polyfill kick in and wire up orientation API support?

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics
