I upgraded my copy of AGS, and now the font is displaying anti-aliased.
Thank you Calin Leafshade for all the support in IRC!
However, now I'm in an odd predicament:
The font is cut off at the top.

My font is imported to be 32px tall.
I tried a smaller height (24px) but it was still cut off.
Ah, nevermind. It was because I was using a TrueType font.

Converting the font to OpenType fixed the cut-off text issue.
