This file contains one class, called ColorDB, and several utility functions.
The class must be instantiated by the get_colordb() function in this file,
passing it a filename to read a database out of.
The get_colordb() function will try to examine the file to figure out what the
format of the file is. If it can't figure out the file format, or it has
trouble reading the file, None is returned. You can pass get_colordb() an
optional filetype argument.
Supporte file types are:
X_RGB_TXT -- X Consortium rgb.txt format files. Three columns of numbers
from 0 .. 255 separated by whitespace. Arbitrary trailing
columns used as the color name.
The utility functions are useful for converting between the various expected
color formats, and for calculating other color values.
