Changes to make gdk-pixbuf threadsafe (#157310, #157306, Colin Walters):

Browse Source 
2004-11-12  Matthias Clasen  <mclasen@redhat.com>

	Changes to make gdk-pixbuf threadsafe  (#157310, #157306,
	Colin Walters):

	* gdk-pixbuf-io.h (enum GdkPixbufFormatFlags): Add
	GDK_PIXBUF_FORMAT_THREADSAFE to indicate that an image loader
	is threadsafe.

	* gdk-pixbuf-io.c (get_file_formats, _gdk_pixbuf_load_module):
	Use a lock to make initialization of global data structures
	threadsafe.
	* gdk-pixbuf-private.h:
	* gdk-pixbuf-io.c (_gdk_pixbuf_lock, _gdk_pixbuf_unlock):
	Auxiliary functions which use another lock to protect
	threadunsafe image loaders.

	* gdk-pixbuf-io.c (gdk_pixbuf_real_save):
	(save_to_callback_with_tmp_file):
	(gdk_pixbuf_real_save_to_callback):
	(gdk_pixbuf_new_from_xpm_data):
	(_gdk_pixbuf_generic_image_load):
	* gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
	* gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module):
	(gdk_pixbuf_loader_close):
	(gdk_pixbuf_loader_finalize):
	Use _gdk_pixbuf_lock() and _gdk_pixbuf_unlock().

	* io-ani.c, io-bmp.c, io-gif.c, io-ico.c:
	* io-jpeg.c, io-pcx.c, io-png.c, io-pnm.c:
	* io-ras.c, io-tga.c, io-wbmp.c, io-xbm.c:
	* io-xpm.c: Mark as threadsafe.

	* io-tiff.c: Remove pointless locking, mark as
	threadunsafe.
