[w3m-dev 03837] Re: gif animation with no delay_time

Browse Source 
* w3mimg/fb/fb_gdkpixbuf.c (get_animation_size): add delay
			check delay_time
	(get_image_size): no need delay time
	(fb_image_load): check delay
	(draw): no bg
* w3mimg/fb/fb_w3mimg.c (w3mfb_show_image): delete delay skip loop
* w3mimg/x11/x11_w3mimg.c (get_animation_size): add delay
			check delay_time
	(x11_load_image): check delay
	(x11_get_image_size): no need delay time
