       s3dw_widget - s3d widget information


       #include <s3dw.h>


           struct _s3dw_widget {
                int type;
                s3dw_widget *parent;
                s3dw_style *style;
                int nobj;
                s3dw_widget **pobj;
                int focus;
                int flags;
                float ax;
                float ay;
                float az;
                float as;
                float arx;
                float ary;
                float arz;
                float width;
                float height;
                uint32_t oid;
                void *ptr;
                float x;
                float y;
                float z;
                float s;
                float rx;
                float ry;
                float rz;


       This is the most basic widget type, it contains all the "general"
       widget information. If you want to move a widget, you´d change x,y,z,s
       and rx,ry,rz and call s3dw_moveit to turn your action reality. Every
       other widget has this type as first entry, so a simple typecast to
       s3dw_widget will give you the widgets "general" information. For
       typecast, you may use S3DWIDGET().

       The pointer ptr allows linking to user-specific data structures. That
       comes in handy if the widget is called back by an event, and the
       program must now find out on which data the user reacted.
