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
