Bug 801: Revise Graph VBAA (Add border dropping MSAA; Test diff. AA modes incl. FXAA2) ; Test exp. LineAA ; Misc Changes

- Revise VBAA
  - Add border to FBO dropping MSAA
    - This automatically gives AA for edges on FBO boundary

  - Correcting ceil-diff, use object-diff instead of win-diff (diff := ceil(a)-a, w/ float a)

  - Reorg shader - using includes to test diff. AA modes:
    - [poles, wholeedge] * [equalweight, propweight]
    - fxaa2

- Exp. LineAA (disabled)
  - Test ROESSLER-2012-OGLES for detected rectangles only
  - Test boundary line detection

See screenshots: <http://jogamp.org/files/screenshots/graphui/20140322/>
