While font support isn't perfect, it is much better now than
it has been. Some of the projects Red Hat will be working on in the
future to improve things even further will be a graphical
configuration tool for adding and removing fonts and font
directories, and further development of the X Font Server. During
the course of Red Hat Linux 6.0's development, we became aware of a
number of large security holes in xfs's
network code, and for this reason we were forced to temporarily
disable support for TCP connections. We understand that there are
some environments which rely on xfs to
act in a more traditional, network font serving fashion, and we will
be providing an update to X which provides an unmodified binary for
such purposes shortly. As a longer term solution, we hope to remove
all such vulnerabilities in the font server and bring the code into
the modern era, as it has been neglected for several years while the
rest of X has seen more attention.
X still does not support font smoothing, also
known as anti-aliasing. Font smoothing makes small curves in a
character appear less jagged by filling in gaps with gray colors,
instead of simply drawing the character in black and white. This is
a physical limitation of the current X font model, but people are
actively pursuing solutions to overcome this hurdle.
