  First of all -- thanks for the response. Now, that leads to these
  two additional questions:

    1. what would be an ideal application to use for factoring out
    the grid layout issues ? Basically what app makes the best out
    of FreeType rasterization ? Would it be ftview ?

    2. I'm a software developer myself so I'm willing to work
    on Xterm to address the grid positioning issues. Can you 
    please provide me with any pointers to how this is supposed
    to be addressed ?
