/**
 * @file panel_prev_model.h
 * @brief Defines a panel which is to be added to a wxFileDialog via
 * SetExtraControl();
 * The panel shows a preview of the module being edited and provides controls
 * to set the offset/rotation/scale of each model 3d shape as per KiCad's
 * current behavior. The panel may also be used in the 3D configuration dialog
 * to tune the positioning of the models without invoking a file selector dialog.
