ComponentsInfoBox: arange text to the left border if no picture is painted

changed isPainted() to isPicPainted(), return of isPicPainted() value was
not marked-down to false and isPainted() means the container frame and
isPicPainted() means the picture itself, so the last state was wrong. Now
it should work fine.

Btw: scope of x_text reduced, is only required in member paintText()
