[Cuis-dev] Transparent Form ?

[Hilaire Fernandes]

Hi Juan,

Work nicely! Thanks.

Regarding speed, now I can tell you Cuis' Morph is super fast.

See https://youtu.be/beIZnmhx2HU

I have to record the video up to 60Hz to get a taste of the smoothness 
of the animation. And the youtube video does not show this.

For a smooth rendering, see:

The animation framework used to animate on a given duration comes from 
Pharo. Under Pharo it is not smooth at all.

With Cuis, one can make very nice and smooth UI.
