2.5

Useful goodies: most buttons for Image window back.
Not every button works! But what you can do:

- press Nkey to show/hide options
- use curves, with realtime updating
- image properties panel, load, browsing layers,
  setting types
- paint panel
- plus new paint color picker panel! (why it wasn't
  there in 2.4x is probably obvious, but now it can!)

Hrm... radial control should be added here too, and a nice
paint size cursor?
