Ton Roosendaal 0ce9abf41d - converted full materialbuttons... 
EEEK! It doesn't look well yet! Hopefully it inspires others to come
  with great solutions.
- the material buttons have 6 panels, three of them merged
- some drawing errors in preview render
- made settings for new Material that makes sense for Flares
