graphics/twm4nx/src/window.cxx: Add flags to CWindow initializer to support customization of toolbar buttons and other window properties. Add framework to handle toolbar button presses. Window minimization (aka, iconification) does not work. graphics/twm4nx/src/input.cxx: Add support to scaling touchscreen. Not needed for the current testing because the touchscreen naturally matches the display size. But will be needed, along with calibration scren, in the future.
