Summary     : PostScript Type 1 font rasterizer
Description :
T1lib is a rasterizer library for Adobe Type 1 Fonts. It supports
rotation and transformation, kerning underlining and antialiasing. It
does not depend on X11, but does provides some special functions for
X11.

AFM-files can be generated from Type 1 font files and font subsetting
is possible.

This update fixes several security flaws in t1lib (flaws in AFM parser and
when handling specially crafted Type1 fonts).
