Description
When the TEXT_ANTIALIAS hint is set to ON, then optimized
text antialiasing loops are used to render the text.

But, when the regular ANTIALIASING hint is set to ON, a
general path is used to render the text from gray-bits
masks.

The results are visually the same, but the optimized text
antialiasing loops go through much less code to produce
those results.

This can be seen by running J2DBench with the various
combinations of the Graphics AA and Text AA hints.  The
performance is nearly 4x faster with the Text AA hint
on Solaris/Sparc.

EVALUATION We need to update the loop selection when we do pipe validation. ###@###.### 2005-06-15 00:15:56 GMT
