Revert "Reland "Revert "remove legacy code for text attributes on paint"""

This reverts commit 3c03c851ad50308cc55eabcad149090a07a814d6.

Modification was to copy/assign fBitfieldsUInt rather than fBitfields,
since fBitfields might be smaller, and therefore ignore some bits that
we do use in hashing, etc.
