NAME
       s3d_set_callback - sets a callback

SYNOPSIS
       #include <s3d.h>

       void s3d_set_callback(uint8_t event, s3d_cb func);

DESCRIPTION
       Sets a callback for a certain event. this is very useful for event-oriented applications. event callbacks will not interrupt each other or
       the mainloop.

	   Warning
	   Defining callbacks will only work after calling s3d_init()

	    #include <inttypes.h>

	    void obj_click(struct s3d_evt event)
	    {
		    printf("object id %"PRIu32" got clicked", *((uint32_t *)event->buf));
	    }
	    ...
	    s3d_set_callback(S3D_EVENT_NEW_OBJECT, obj_click);
	    // this will tell you when a object got clicked
