Easy way to resize Electron window to a specific size (e.g. for video production)

[tkoolen]

Currently using

open(vis, Blink.Window(Dict(:width => 1280, :height => 720, :useContentSize => true)))

Need to turn that into modifying an existing window, and perhaps adding a toolbar menu option for this.

I've updated the title of this issue following the dependency change in v0.16.0, from Blink.jl to Electron.jl.
