JAWTUtil/MacOSXWindowSystemInterface-pbuffer: Cleanup / More DEBUG info

JAWTUtil.getJAWT(..):
  - better local var names
  - one time init
  - add DEBUG trace
JAWTUtil.<init>:
  - add offscreenLayer info

MacOSXWindowSystemInterface-pbuffer.m:
  - remove warning: access of protected vars from outside class
  - better local var names
  - more DEBUG info (pbuffer texture)
