Revert "Splitting up rendering of text on screens with a vertical resolution > 25 into separate display lists to see it if might help with the ATI driver crash."

This reverts commit 774ca1268b84664fac3167b1d1972de13386b817.
Getting rid of tessellator, maybe that'll fix the ATI crash... read somewhere that ATI drivers derp when VBOs are used inside display lists.
