Functions
Gan_Bool	gan_image_get_active_subwindow_vfield2D_s (const Gan_Image *image, Gan_ImageWindow *subwin)
	Computes bounding box of non-zero pixels in grey-level image.
Gan_Vector2_s *	gan_image_get_pixptr_vfield2D_s (const Gan_Image *img, unsigned row, unsigned col)
	Return a pointer to a pixel from a 2D vector-field short image.
Gan_Vector2_s **	gan_image_get_pixarr_vfield2D_s (const Gan_Image *img)
