“At the heart of PDF is its ability to describe the appearance of sophisticated graphics and typography. This ability is achieved through the use of the Adobe imaging model, the same high-level, device-independent representation used in the PostScript page description language.” PDF Reference, 6th ed. (2006), pp. 34.
“At the heart of liberty is the right to define one’s own concept of existence, of meaning, of the universe, and of the mystery of human life. Beliefs about these matters could not define the attributes of personhood were they formed under compulsion of the State.” Planned Parenthood v. Casey, 505 U.S. 833, 852 (1992).
