When running rtcheck it is not possible to specify a grid dimension
over 32768. Worse, the program runs, but with the default grid
dimesnions (512x512). If the -g and -G options are used, it is
possible to get higher values.

There appears to be a model-size limit associated with this as well.
I can specify a grid size of 0.3mm on some geometry, but not on
others.

    This is caused because the RTUIF is allocating a pixel
    buffer. For large grids this consumes memory (or the malloc
    fails) even though the memory is not needed. We really
    should change the RTUIF to not malloc if the memory isn't
    needed.

    This was (one of) the impetus that caused g_qa to be written. Users should now
    use g_qa for this function.
