Functions
Gan_Image *	gan_image_set_gen_gl_ui (Gan_Image *img, unsigned long height, unsigned long width, unsigned long stride, Gan_Bool alloc_pix_data)
	Set format, type, dimension and stride attributes of an image.

	Form an image with specific format, type, dimensions and stride.
Gan_Bool	gan_image_get_active_subwindow_gl_ui (const Gan_Image *image, Gan_ImageWindow *subwin)
	Computes bounding box of non-zero pixels in grey-level image.
unsigned int *	gan_image_get_pixptr_gl_ui (const Gan_Image *img, unsigned row, unsigned col)
	Return a pointer to a pixel from a grey-level unsigned int image.
unsigned int **	gan_image_get_pixarr_gl_ui (const Gan_Image *img)
