Transparency support

[luisbocanegra]

I just thought about transparency because it could do for a cool effect along with the Force Blur kwin effect. Imagine Qt Apps following the MY Breeze colour scheme (like Dolphin), with the same transparency as the panel : it would create some good looking coherency I think. Of course, the amount of work you say this would require is absolutely not justifiable just for this.

I think this'd be a great idea. Right now I'm using a mix of better blur, klear and klassy, and it works great honestly. Caveat is that klear is just not customizable, and I have to stick with having transparency in zoom if I want it elsewhere, which is not great.

Klear developer said he'd be trying to move it from kwin scripts to plasma addons.
