在Linux下实现magnification功能

	work better.

2005-03-08  Bill Haneman <[e-mail]>

	* configure.in, README, NEWS:
	Revved to 0.12.0, for gnome 2.10.0.
	
2005-02-04  Bill Haneman <[e-mail]>

	Fix for bug #164371.

	* magnifier/magnifier.c:
	(magnifier_adjust_source_size): New.
	(magnifier_set_property): Call magnifier_adjust_source_size when
	changing target bounds, if target and source displays are the same.

	* magnifier/zoom-region.c:
	(zoom_region_set_viewport): Re-create the pixmap when the viewport
	changes, since the source-bounds may have changes as a result.
	[This can happen when source-display==target-display]
	
2005-02-04  Bill Haneman <[e-mail]>

	* configure.in: Revved to 0.11.14.
	
	* README, NEWS: Updated for 0.11.14.

	* magnifier/zoom-region.c:
	Added some forward declarations for existing funcs.
	(_rectangle_clip_to_rectangle): Implemented.
	(zoom_region_clip_to_target): Renamed to
	(zoom_region_clip_scaled_pixmap). Not yet used.
	(zoom_region_update): Create the pixmap if not already
	created; this makes the 'update current' calls at init time work,
	so that the initial magnified target window isn't wholly 
	or partially blank.
	(impl_zoom_region_mark_dirty): Clip to the source, not target,
	bounds.
	(impl_zoom_region_set_mag_factor): Create a pixmap that's
	big enough for any update/mark-dirty request.  We were
	missing some parens () in our calc.  Fixes 166282.

2005-01-18  Bill Haneman <[e-mail]>

	* README, NEWS : Updated for 0.11.13.
	
	* magnifier/magnifier.c: Moved the 'get source bounds' call
	back to before the zoom-regions-restore call.  Fixes bugs #164444
	and (partially) #164371.  Note that this fix will cause "self-magnification"
	if the source display is changed to be the same as the target
	display, after initial invocation, as a minor side-effect.
	
2005-01-17  Bill Haneman <[e-mail]>
	
	* configure.in: Revved to 0.11.13.

	* magnifier/magnifier.c:
	(magnifier_cursor_notification_init): Keep track of cursor 
	connection, close the old one, remove the gsource (which was 
	causing a hang), and reopen a new one when SOURCE changes.
	Fixes #164491.

	* magnifier/zoom-region-private.h:
	Store the update handler gsource.

	* magnifier/zoom-region.c:
	(zoom_region_do_dispose): Brute-force remove the update handler gsource,
	because g_idle_remove_by_data isn't reliably removing 
	all the idle handlers.
	(zoom_region_queue_update): Only add the process-updates idle
	handler if one isn't already running.
	(zoom_region_coalesce_updates): Check zoom_region->priv->q before
	checking its length.  Reset the update_handler_id to 0 when
	you've emptied the queue.
	Completes fix for #164275.
	
2005-01-16  Bill Haneman <[e-mail]>

	* configure.in, NEWS, README: Updated for 0.11.12.

	Fixes for bug #164275.
	
	* magnifier/damage-client.c:
	(magnifier_damage_client_init):
	Keep track of the damage-client gsource, and remove it
	when re-initializing the damage connection on 
	source DISPLAY change.  
	Make sure to connect to the source display, not the
	default DISPLAY.

	* magnifier/magnifier-main.c:
	Removed some excess output to stderr.

	* magnifier/magnifier.c:
	(MagnifierZoomRegionSaveProps): New struct for persisting
	zoom region params during a brute-force reparent.
	(magnifier_unref_zoom_region): Don't unref here, we do it
	elsewhere.
	(magnifier_reparent_zoom_regions): Superceded by 
	separate save/restore methods.
	(magnifier_zoom_regions_save): New, persist the zoom region
	data before disposing, during brute-force reparent.
	(magnifier_zoom_regions_restore): New, create and
	new zoom region list from saved set.
	(magnifier_set_property): Handle source-display setting 
	differently - save the old zoom list, destroy and recreate the
	main GtkWindow, and recreate the zoom list.
	Restore the main window's target bounds on re-create.
	(impl_magnifier_get_target_display): Fixed cut/n/paste
	error in the return of 'target display'.
	
	* magnifier/zoom-region.c:
	Added conditionally-compiled assertions for lifecycle testing.
	Added more sanity checks before indirections through pointers, to
	help prevent SEGVs.
	(zoom_region_update_current): Tested GDK_IS_DRAWABLE of pixmap.
	(zoom_region_paint_crosswire_cursor): Init an unused part of 
	the GdkRectangle, to keep valgrind happy.
	(zoom_region_create_pixmap): Recompute the exposed viewport
	when creating the initial pixmap.
	Added code to return ZOOM_REGION_ERROR_NO_TARGET_DRAWABLE under
	appropriate conditions.
	(zoom_region_do_dispose): Remove the GSource for updating the
	pointer, because it doesn't get removed by
	g_idle_remove_by_data.  [Fixes SEGV bugs when changing source DISPLAY]
	(zoom_region_private_init): Initialize the various bounds
	rectangles.
	(zoom_region_finalize): Check the status of the zoom region and
	magnifier widgets before calling gtk_container_remove.

	Also some minor cleanup.

	* magnifier/zoom-region.h:
	Added conditional 'alive' field for assertion testing.

	* magnifier/zoom-region-private.h:
	Added member for pointer-update gsource handler.

	last_drawn_crosswire_pos, not the backing rect.
	(zoom_region_paint_crosswire_cursor): Fix broken GDK_DRAWABLE
	test, reinstates drawing of crosswire.
	Use 16 bits of color mask instead of 8, for GdkColor inversion
	mask.  Set the gdk_gc clip mask to NULL if we haven't been passed 
	one, don't reuse the stale one.
	(zoom_region_paint_cursor): Save the last_drawn_crosswire_pos
	before we clip the cursor_backing_rect to the current screen.
	(zoom_region_update_pointer): Create a clip region which
	encompasses the whole zoom region, before updating the cursor
	image.
