OGL: PIT: Many of the panels in Java2Demo are blank when Antialias is de-selected

I am launching Java2Demo using the current PIT build (b77) with OpenGL flag turned on. I am surprised to see some of the demo panels appearing blank when I de-select the Antialias checkbox. They appear properly when antialias is enabled.

Do the following:
1. Launch Java2Demo with OpenGL flag on 03/14 or 03/18 PIT build
2. Go to ARCS_CURVES tab and de-select the 'Antialias' checkbox.
3. Proceed to Clipping Tab. You would see 'Areas', 'Intersection' panels appearing blank. 'JAVA' text shown in 'Text' panel will not be filled properly.
4. Goto Colors Tab. BullsEye will not be rendered at all. Rotator3D will not have any colors on it.
5. Goto 'Fonts' tab. The bounding rectangle in the 'Highlighting' panel will not be seen.
6. Goto 'Lines' tab. You will not see 'Joins'. You will not see the circle in 'LineAnim'

Likewise, there are issues in almost every tab. All these issues are reproducible only on the current PIT build (b77) and not reproducible on Mustang-b76. The above issues are noticed only when Antialias is deselected.
I am able to reproduce this on SolSparc10 as well as WinXP. This is indeed a regression in the current PIT.
