Adjust ROI

After Photo Alignment, 3D Viewer should display the tie points and a yellow Region of Interest (ROI) box. The default ROI covers all of the scene. If you only need to reconstruct some region, you can adjust the ROI to reduce computation for future steps. Building Dense Cloud, Building DEM / DSM and Building DOM / TDOM only work in ROI.
