 no, it will not be done at all.
 a typical virtual keyboard does the followings:
  - Draw the separated characters on its window using a specified font.
  - Process 'ButtonPress' events and catch them when the mouse is
    pointing to a (previously drawn) characters glyph.
  - Get the glyph code (previously stored) and Release a 'KeyPress' event that
    corresponds to the character followed by a 'KeyRelease' when it recieves
    a 'ButtonRelease' event.
 As you see, shaping is not needed at all and a virtual keyboard can work
 without even drawing the glyphs on its window given that you know their
 positions.
