apps/graphics/tmw4nx and apps/graphics/slcd:  This seems the last of the show stopper bugs.  All seems functional.

    apps/graphics/slcd:  Correct some errors found in early texting.  Now the Twm4Nx::CClock window comes up, but there are problems with the way that the segments are being displayed.

    apps/graphicx/twm4nx:  CClock is complete and compiles correctly.  Crashes with a hardware when the clock is selected from the Main Menu, however.
