/*!
* \brief WindowManager::launchRegionWindow is called when the user has dragged a region across the screen.
* This function launches the window allowing the user to see the region they have created,
* and to specify options for that region (name, threshold, notes). The user may only save a region IF that region has
* a name.
*
* This function also displays an image of the current frame with the region the user selected drawn on it.
* See the function saveFrameWhenRegionCreated for a description of that.
*
* \see RegionWindow.
*
* \param projName The project associated.
* \param vidName The video we are adding a region to.
* \param regionName The name of the region (if this is an edit/update).
* \param x The x of the region (pixels)
* \param y y of the region (pixels)
* \param width width of the region (pixels)
* \param height height of the region (pixels)
