Description

After the Slicer update introduced in #131, annotations can not be scaled using Right-Click near annotation line & drag.

Originally described in the "Mouse operations" section of the README:

Turns out that Scale/Translate/Rotate functionalities are available.

• <Alt> + Right Click near annotation line to scale -> :x: (Crash)
• <Alt> + Left Clicknear annotation line to rotate -> :heavy_check_mark:

It was not working on Ubuntu because the Alt + Right Click was intercepted by the windows manager, this was addressed re-binding to <Super> + Right click. See https://askubuntu.com/questions/521423/how-can-i-disable-altclick-window-dragging
