在Linux下实现magnification功能

2007-03-09  Carlos Eduardo Rodrigues Diogenes  <[e-mail]>

	* configure.in: Version 0.14.3.

2007-03-09  Carlos Eduardo Rodrigues Diogenes  <[e-mail]>

	* magnifier/magnifier-main.c: Make the -v CLI option means only
	--vertical. To get the magnifier version the --version option must be
	used.

2007-03-03  Carlos Eduardo Rodrigues Diogenes  <[e-mail]>

	* configure.in: post-release incrementing to 0.14.3.

2007-03-02  Carlos Eduardo Rodrigues Diogenes  <[e-mail]>

	* configure.in: Version 0.14.2.

2007-03-02  Carlos Eduardo Rodrigues Diogenes  <[e-mail]>

	* magnifier/magnifier.c: More informative message when running a 2nd
	magnifier instance. Thanks Michael Broadbent for the patch;
	* magnifier/magnifier-main.c: Added the --version option;
	* magnifier/GNOME_Magnifier.server.in.in: Added the --ignore-composite
	option to the bonobo start server file, since COMPOSITE support still
	have some performance issues and COMPOSITE use make some applications
	behave buggy;
	* magnifier/zoom-region.c: Clamp the input setted by setBrightness and
	setContrast;
	* magnifier/gmag-events.c: Initialize the damaged variable in the
	GmagWin structure. This was causing crashes in some platforms and
	initialize variables is always a good thing to do :-) Thanks Willie
	Walker for create the patch and help find this issue.

2007-01-31  Carlos Eduardo Rodrigues Diogenes  <[e-mail]>

	* configure.in: Added the new file 'gnome-mag-1.0-uninstalled.pc' to
	the AC_OUTPUT list;
	Add #include line to make composite extension enabled on Solaris.
	Thanks Jeff Cai for the patch!
	* gnome-mag-1.0-uninstalled.pc: New file to help build gnome-mag in the
	Solaris OS. Thanks Brian Cameron for this!

2007-01-08  Carlos Eduardo Rodrigues Diogenes  <[e-mail]>

	* configure.in: post-release incrementing to 0.14.2.

2007-01-08  Carlos Eduardo Rodrigues Diogenes  <[e-mail]>

	* configure.in: Change the test for XDamage and XFixes to only look at
	the directories passed by --x-libraries. Added test for XRender, XShape
	and XComposite. Changed the behavior of how the test are done. XDamage
	is only looked if XFixes is finded, as well as the XComposite is only
	searched if XDamage is present.
	* damage-client.c: Removed. This file was incorpored in gmag-events.c.
	* damage-client.h: Removed.
	* gmag-events.c: New file added. This file is responsible to gnome-mag
	and X comunication. This one initialize all the extensions and handle
	events.
	* gmag-events.h: Interface to gmag-events.c.
	* magnifier-main.c: Added the option ignore_composite to
	MagnifierOptions structure. Added comments after the struct
	members inicialization.
	* magnifier-private.c: Added two new members: GdkWindow *overlay and
	GdkPixmap *source_drawable, the first hold an reference to the overlay
	window created by XCompositeGetOverlayWindow and the second is where
	the screen is composited.
	* magnifier.c: Some headers reorganized; Removed functions from this
	file: magnifier_free_cursor_pixels, magnifier_get_source_pixbuf,
	magnifier_cursor_notify and magnifier_cursor_notification_init. The
	first two function were putted in the new file
	magnifier/gmag-events.c with the prefix magnifier removed and the new
	one, gmag_events, added. The function magnifier_cursor_notify was
	incorporated in the handler function of XFixes, XDamage and XComposite
	related events gmag_events_handler, while the
	magnifier_cursor_notification_init was putted inside gmag_events_init.
	(magnifier_reset_overlay_at_idle): This new function was added to
	reparent the magnifier window to the overlay window after the magnifier
	initialization. This grants that the magnifier window will not be
	obscured by popup windows.
	Thanks to everyone that report bugs about all these modifications and
	the Sun team that tested it and make possible a very good COMPOSITE
	support in gnome-mag available!

2007-01-08  Christian Kirbach  <[e-mail]>
  
  	With hints from Christian Persch
	* configure.in, magnifier-main.c:
  	  Do the transition from popt to glib's GOption command line parsing,
	  one of the current Gnome goals. Require glib >= 2.11.1.
  	* magnifier.c: Remove obsolete dependency on <popt.h>.

	component.

	option iterates throw all the colorblind filters.

	* magnifier/zoom-region.c: make the scaled pixbuf be recalculated when
