1) Is there a way to get the current states of these for a given
context? I don't see any "getters" in CGContext.h
2) So, generally speaking, I should set BOTH ShouldAntialias(true) and
ShouldSmoothFonts(true) to ensure that the user gets what they want as
set via the Appearance options?
I'm trying to figure out right now why text I'm drawing via ATSUI
doesn't have the same anti-aliasing/smoothing that the same
text/font/size does in TextEdit.app. I'm asking some ATSUI-related
questions though on carbon-dev -- perhaps this list would be more
appropriate?

Three options of rendering text:
1) Non-antialiased text (these are the the 1 bit hinted bitmaps). In
this case antialiasing is off
2) Antialiased text (this is the same as "Standard" font smoothing in
the Font Smoothing setting in Appearance pane of System Preferences.
3) LCD based antialiasing, which uses the r,g,b subpixels to render
text. In this case Font Smoothing and antialiasing are both true. The
quality of the font smoothing is determined by the Font Smoothing
setting in Appearance pane of System Preferences.

What is the difference betweeen Font Smoothing and Antialiasing?
Or perhaps a better question, what exactly is Font Smoothing?
Can the font smoothing and antialiasing GState fields contain
opposing values (font smoothing without antialiasing, or vice-versa)?
