[Xcircuit-dev] Re: xcircuit colormap err

[Eric Y. Chang]

Hi Tim.  Do you need any help or investigation on this matter?  Of
course, my system does not have the LookupColor bug, but I can
easily retrigger the limited color table size problem.  How does
removing the line help the case in which the pixel value that 
comes back from LookupColor is bogus?  I first thought that the
color table generation routine had problems, but it is in fact what
saved the day when the colors were limited.
