Typeface.NORMAL/BOLD/ITALIC/ITALIC_BOLD is used for specifying relative
from current Typeface. For example
Typeface face = Typeface.create("serif");
Typeface thickerFace = Typeface.create(face, Typeface.BOLD);
Typeface moreThickerFace = Typeface.create(tickerFace, Typface.BOLD);
For the purpose of providing font information, we should use weight/italic
value instead of style in Typeface.
The Columns.STYLE field was kept for preventing runtime crash of demo
apps.
