// The tweakTransition() is called from extension.js to tweak a window's open / close
// transitions - usually windows are faded in / out and scaled up / down by GNOME Shell.
// The parameter 'forOpening' is set to true if this is called for a window-open
// transition, for a window-close transition it is set to false. The modes can be set to
// any value from here: https://gjs-docs.gnome.org/clutter8~8_api/clutter.animationmode.
// The only required property is 'opacity', even if it transitions from 1.0 to 1.0. The
// current value of the opacity transition is passed as uProgress to the shader.
// Tweaking the actor's scale during the transition only works properly for GNOME 3.38+.
