Collect statistics on the use of open source

TOAST UI ImageEditor applies Google Analytics (GA) to collect statistics on the use of open source, in order to identify how widely TOAST UI ImageEditor is used throughout the world. It also serves as important index to determine the future course of projects. location.hostname (e.g. > “ui.toast.com") is to be collected and the sole purpose is nothing but to measure statistics on the usage. To disable GA, use the following usageStatistics option when creating the instance.

const options = {
    ...
    usageStatistics: false
}

const imageEditor = new tui.ImageEditor('#tui-image-editor-container', options);

Or, include tui-code-snippet(v1.4.0 or later) and then immediately write the options as follows:

tui.usageStatistics = false;

💾 Install

Using npm

npm install --save @toast-ui/vue-image-editor

If you install other packages, you may lose dependency on fabric. You need to reinstall the fabric.

```
npm install --no-save --no-optional fabric@~4.2.0
```
