[w3m-dev 03282] Re: w3m-img for framebuffer update
* w3mimg/fb/fb.c (fb_image_new): ignore no image
				calloc multiple images
		(fb_image_fill): added
		(fb_image_draw): width, height fix
		(fb_image_rotate): fix typo
		(fb_image_copy): added
		(fb_frame_new): added
		(fb_freme_free): added
		(fb_frame_rotate): added
* w3mimg/fb/fb.h (FB_IMAGE): add num, id, delay
		(fb_frame_new): added
		(fb_frame_free): added
		(fb_frame_rotate): added
* w3mimg/fb/fb_gdkpixbuf.c (get_image_size): animation support
		(fb_image_load): animation support
		(draw): add bg, x, y, w, h args
* w3mimg/fb/fb_img.h (fb_image_load): return FB_IMAGE**
* w3mimg/fb/fb_imlib2.c (fb_image_load): return FB_IMAGE**
* w3mimg/fb/fb_w3mimg.c (w3mfb_show_image): animation support
