    Touch a window/widget/form to ensure it gets drawn by IDA.

    XXX/HACK:

      We need to ensure that widget we will analyze actually gets drawn
      so that there are colors for us to steal.

      To do this, we switch to it, and switch back. I tried a few different
      ways to trigger this from Qt, but could only trigger the full
      painting by going through the IDA routines.
