Siggraph show commit!

- pending commit for OSX intel systems, with intel graphics. These now call
  an extra swapbuffers after glFlush(). Code is ifdeffed, and doesnt affect
  other systems.

- show-off commit: option to have transparent nodes over the composite
  result. Only draws Image for active Viewer Node now, and image doesnt
  translate nor zoom (which isnt bad though).
  Set in themes the alpha color of "node backdrop" to make nodes
  transparent.
