Bruce Evans 2610c9f2b2 Add teken_256to16() to convert xterm-256 256-color codes to xterm 16-color
codes.  This will be used to fix bright colors.

Improve teken_256to8().  Use a lookup table instead of calculations.  The
calculations were inaccurate since they used indexes into the xterm-256
6x6x6 color map instead of actual xterm colors.  Also, change the threshold
for converting to a primary color: require the primary's component to be
2 or more higher instead of just higher.  This affects about 1/5 of the
table entries and gives uniformly distributed colors in the 6x6x6 submap
except for greys (35 entries each for red, green, blue, cyan, brown and
magenta, instead of approx. only 15 each for the mixed colors).  Even
more mixed colors would be better for matching colors, but uniform
distribution is best for preserving contrast.

For teken_256to16(), bright colors are just the ones with luminosity >=
60%.  These are actually light colors (more white instead of more
saturation), while xterm bright colors except for white itself are
actually saturated with no white, so have luminosity only 50%.

These functions are layering violations.  teken cannot do correct
conversions since it shouldn't know the color maps of anything except
xterm.  Translating through xterm-16 colors loses information.  This
gives bugs like xterm-256 near-brown -> xterm-16 red -> VGA red.

FreeBSD Source:

This is the top level of the FreeBSD source directory. This file was last revised on: FreeBSD

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.

The buildkernel and installkernel targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags.

Building a kernel is a somewhat more involved process. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.

Note: If you want to build and install the kernel with the buildkernel and installkernel targets, you might need to build world before. More information is available in the handbook.

The kernel configuration files reside in the sys/<arch>/conf sub-directory. GENERIC is the default configuration used in release builds. NOTES contains entries and documentation for all possible devices, not just those commonly used.
