	* libnautilus-private/nautilus-directory-async.c (thumbnail_done),
	(thumbnail_loader_size_prepared), (get_pixbuf_for_content),
	(thumbnail_start):
	* libnautilus-private/nautilus-file.h:
	Scale down huge pixbufs when loading. Massively speed up loading of
	directories where the original image is used as thumbnail.
	Also try to write the whole file at once rather than writing in chunks.

	* libnautilus-private/nautilus-file-private.h:
	* libnautilus-private/nautilus-file.c (nautilus_file_get_icon):
	Rewrite some flaky parts of thumbnailing.

	Never scale any thumbnails up.
	Always compose thumbnail on the fly instead storing it once and
	scaling it up and down.
	Add flag to force that thumbnail size matches
	the output icon size for tree view.

	* src/file-manager/fm-list-model.c (fm_list_model_get_value):
	Use this flag.
