Reset block_count to 0 for all application extensions, otherwise the data

2003-06-22  Matthias Clasen  <matthias@localhost.localdomain>

	* io-gif.c (gif_get_extension): Reset block_count to 0 for all application extensions, otherwise the data blocks
	of unknown extensions are not propertly skipped.

	Second half of the fix for #106962, handle frames extending beyond the logical screen:

	* io-gif.c (clip_frame): New helper function to clip a rectangle to the logical screen size of the gif.
	(maybe_update): New helper function to call update_func only if the rectangle is not completely off-bounds.
	(gif_get_lzw): Read frames extending outside the logical screen size, but be careful clip to the logical screen size
	when operating on the composite pixbuf and when calling update_func.
	(gif_init): Set the animation size to the logical screen size.
	(gif_get_frame_info): Don't refuse to load images with frames extending beyond the logical screen size.

	* io-gif-animation.c (gdk_pixbuf_gif_anim_frame_composite): Be careful to clip all rectangles to the logical screen
	size, also handle the fact that frames may be completely off-bounds.
