several cosmetic changes to the node-editor

+ changed lines connecting nodes:
   they now use a linewidth of 1.5px for the light foreground and 4px for the dark background.
   this should fix node-lines not being visible on almost black or all white backdrops.
+ muted nodes now also show a red tinted header if they are hidden (collapsed)
+ both active and selected nodes show a (now properly antialiased) highlighting frame
+ fixed a small error in dropshadow code resulting in a gap at borders
+ fixed a tiny error for the collapsing indicators (triangles) - they were not symmetrical.

Ton will add proper theme colors for the node-editor in the coming days.
