Squashed commit of the following:
apps/graphics/twm4nx: The calibration seems to be functional. Needs more testing.
apps/graphics/twm4nx: Extend event handling to support receiving raw, uncalibaated touchscreen inputs. This is needed for touchscreen calibration.
apps/graphics/twm4nx: Extend event handling to support shutting down of externally controlled windows. This is need to end the calibration sequence.
apps/graphics/twm4nx: CCalibration now compiles okay, but is missing event handling logic for touchscreen input and for window termination.
apps/graphics/twm4nx: Move application-related files into different directories to separate them from the core Twm4Nx files.
apps/graphics/twm4nx: A little more progress on calibration display.
app/graphics/twm4ndx: Add files that will support a calibration display. This initial commit is simply the calibration display from NxWM and is not hooked into the configuration or build systems.
apps/graphics/twm4ndx: Compile out cursor support if we are using a mouse
