- Method "Geometry::draw()" has been modified to include a boolean argument "selected". If selected == true, means that current geometry is selected by user, and so it is drawn with a white contour (TODO: change in future versions).
- Added Q_UNUSED macros to Camera::draw()'s arguments for avoiding "Unused argument" warnings.
