Functions
Gan_Bool	gan_image_get_active_subwindow_gla_uc (const Gan_Image *image, Gan_ImageWindow *subwin)
	Computes bounding box of non-zero pixels in grey-level image.
Gan_GLAPixel_uc *	gan_image_get_pixptr_gla_uc (const Gan_Image *img, unsigned row, unsigned col)
	Return a pointer to a pixel from a grey-level alpha unsigned char image.
Gan_GLAPixel_uc **	gan_image_get_pixarr_gla_uc (const Gan_Image *img)
	Return the pixel array from a grey-level alpha unsigned char image.
Gan_Bool	gan_image_mask_window_gla_uc (Gan_Image *img, unsigned r0, unsigned c0, unsigned height, unsigned width)
	Clear image except in specified rectangular region.
Gan_Bool	gan_image_clear_window_gla_uc (Gan_Image *img, unsigned r0, unsigned c0, unsigned height, unsigned width)
