##### an offical release when making enhancements and translation updates. #####
Fri Mar 18 19:52:38 2005 John Ellis <johne@verizon.net>
* pixbuf-renderer.c: Fix broken 2pass queueing so it merges a single
queue item for each tile, and now that a tile holds a queue pointer
there is no need to walk the tile list to find a possible merge victim.
Thu Mar 17 19:23:56 2005 John Ellis <johne@verizon.net>
* image.c, pixbuf-renderer.[ch]: More progress, and 2 pass zoom now
works again (mostly).
Tue Mar 15 23:17:41 2005 John Ellis <johne@verizon.net>
* image.[ch]: Start conversion to use of PixbufRenderer.
* pixbuf-renderer.[ch]: Additions and fixes for use by ImageWindow.
* fullscreen.c, image-overlay.c, img-view.c, info.c, layout.c,
layout_image.c, print.c: Changes for above ImageWindow conversion.
* typedefs.h: Remove unused ImageWindow variables.
Mon Mar 14 20:45:50 2005 John Ellis <johne@verizon.net>
* pan-view.c: Convert to using new PixbufRenderer.
* pixbuf-renderer.[ch]: Clean up and fixes.
Sun Mar 13 10:21:35 2005 John Ellis <johne@verizon.net>
* image.c (image_scroller_start): Unref scroller pixbuf after adding it
as an overlay to avoid leaking it.
* pixbuf-renderer.[ch]: All functions defined in header file are now
implemented.
Fri Mar 11 17:05:36 2005 John Ellis <johne@verizon.net>
* pixbuf-renderer.[ch]: Set up object properties and additional.
Mar 10 19:22:18 2005 John Ellis <johne@verizon.net>
* pixbuf-renderer.[ch]: FIx scrolling to use old method of gdk_draw and
not gdk_scroll, as scroll often invalidates the entire window (!). Also
merged in source tiles code from image.c.
* pan-view.c: Change picked up when testing PixbufRender zoom.
Tue Mar 8 23:26:00 2005 John Ellis <johne@verizon.net>
* pixbuf-renderer.[ch]: Start of turning image drawing portion of
ImageWindow into an actual GtkWidget.
* src/Makefile.am: Add pixbuf-renderer.[ch].
* pan-view.c: Added temporary hack button and callback for testing
PixbufRenderer widget.

* README: Updates.
Major:
----------------------------------------------
+ > pixbuf-renderer.c:
+ > fix two pass render from corrupting it->qd pointer (need one pointer for each queue?).
+ > fix image_change_from_image (to do this need a pixbuf_renderer_move_image).
+ > fix broken zoom out drawing when using source tiles.
+
+ > image.c:
+ > need to keep a list of ImageWindows and provide function to sync options to each object.
+ > test and probably fix delay_flip.
+ > make this a g_object with signals for completed, changed, etc.
+
+
> work on pan view:
> Pick a better keyboard shortcut than Control + J :)
- d> Add warning dialog that it will be slow if the standard thumbnail cache is not enabled.
> Fix occasional redraw bugs when zoomed out.
> Fix occasional odd requests for non-visible tiles when zoomed out (related to above?).
> Fix slowness in image.c with huge grid size by changing use of pre-allocated tile array
w> Fix search scrolling to try to center image and info popup.
> Fix info popup location to opposing horizontal side when near edge of grid.
> Find something to do with middle mouse clicks.
- d> Set drag and drop data to clicked image.
- d> Should the copy/move/rename/delete operations be available here?
- > ^ and if so, should delete key actually work?
- d> searching for same item more than once should step through all matches
+ > should delete key actually work?
> search should highlight all matching images (with toggle?)
> should non-thumbnail images have a drop shadow?
+ > uptimize pixbuf_draw_line (line endpoints should clip to draw region before draw loop)
> time line view:
- d> searching by date should scroll to proper alignment with year/month/day boundaries.
+ > allow use of file date or EXIF (embedded) date.
+ > allow horizontal _or_ vertical orientation.
> calendar view:
w> fix search. (UPDATE: still can not find day containing name/path/partial)
> supports thumbnail size images only, should grey out actual size items in size menu or something...
+ > allow use of file date or EXIF (embedded) date.
> grid view:
> allow sorting by name, date, size, dimensions, etc.
> flower view:
> fix it :)
+ > under consideration:
+ > split view
+
> the info dialog is not set as a transient of the calling window, this causes it to be behind
a full screen window when 'stay above other windows' is enabled.
-d> use doubles instead of floats wherever possible
