GUI features - Transparency and masks?

Blitz3D Forums/Blitz3D Programming/GUI features - Transparency and masks?

1) FUI (I use it, and it does), NGUI, and Swift's GUI do it I know, I'm not sure about the others.

2) Not quite sure. I know FUI has 'skins' but that might just be color scheme changes. I think Sswift's GUI could do it, but it doesn't have windows style gadget as it is more designed for games.
