Subject: SHERLOCK: RT: Fix inventory tooltips when in a scene with a mask

ScummVM simplifies tooltip handling by drawing tooltips directly to the
screen surface. This works well in most cases, but in mask scenes, the
screen is recopied at the end of rendering to apply the mask overlay,
so the tooltip needs to be redrawn after again in order to be seen
