Touchscreen users had no app specific onscreen input methods.
Solution:
Add a virtual numpad and keyboard and show them for editable fields
when [DISPLAY]TOUCHSCREEN in the INI file is 1, yes, or True.
Show the numpad when the field is numeric, else show the full
keyboard.
The input panel is placed below the control it is editing, unless any
part of the panel would be offscreen. In which case, the panel will
be positioned as closely to the control as possible without running
offscreen.
