Based on original patches from Hartmut Kuhse and modified
by Michael Natterer. Changes include:
- remove libexif dependency and add a hard dependency on gexiv2
- typedef GExiv2Metadata to GimpMetadata to avoid having to
include gexiv2 globally
- add basic GimpMetadata handling functions to libgimpbase
- add image and image file specific metadata functions to libgimp,
including the exif orientation image rotate dialog
- port plug-ins to use the new APIs
- port file-tiff-save's UI to GtkBuilder
- add new plug-in "metadata" to view the image's metadata
- keep metadata around as GimpImage member in the core
- update the image's metadata on image size, resolution and precision
changes
- obsolete the old metadata parasites
- migrate the old parasites to new GimpMetadata object on XCF load
Recent Cairo uses SHM transports when available, and exposes the ability
for its users to manage images shared between it and the display.
This allows us to eliminate copies, and if the architecture supports it
even to upload directly into GPU addressable memory without any copies
(all in normal system memory so we suffer no performance penalty when
applying the filters). The caveat is that we need to be aware of the
synchronize requirements, the cairo_surface_flush and
cairo_surface_mark_dirty, around access to the transport image. To
reduce the frequency of these barriers, we can subdivide the transport
image into small chunks as to satisfy individual updates and delay the
synchronisation barrier until we are forced to reuse earlier pixels.
Note this bumps the required Cairo version to 1.12, and please be aware
that the XSHM transport requires bug fixes from cairo.git (will be
1.12.12)
v2: After further reflections with Mitch, we realized we can share the
transport surface between all canvases by attaching it to the common
screen.
v3: Fix a couple of typos in insert_node() introduced when switching
variables names.
v4: Encapsulating within an image surface rather than a subsurface was
hiding the backing SHM segment from cairo, causing it to allocate
further SHM resources to stream the upload. We should be able to use a
sub-surface here, but it is more convenient to wrap the pixels in an
image surface for rendering the filters (and conveniently masking the
callee flushes from invalidating our parent transport surface).

Gegl >= 0.1.8, Babl >= 0.1.6, Gdk-Pixbuf >= 1.24.0, Pango >= 1.29.4,
GLib >= 2.28.8, GTK+ 2.24.7
Which means depending on a gazillion of bug fixes, which means less
pain for GIMP 2.8 users, and less useless bugzilla traffic eating
developer resources.
and completely separate configure and sanity checks for gdk-pixbuf
from GTK+, because it's now distributed as a separate package. Remove
all sorts of conditional compiling based on GDK_CHECK_VERSION() and
CAIRO_VERSION.
Uodate Pango required version and stop using the deprecated
pango_cairo_font_map_create_context(). Compile with
PANGO_DISABLED_DEPRECATED for pango < 1.30.
The version checks for babl and GEGL did not cope correctly with the
minor version upgrade. This change fixes this by introducing a generic
version check.

* all files with a GPL header and all COPYING files:
Change licence to GPLv3 (and to LGPLv3 for libgimp).
Cleaned up some copyright headers and regenerated the parsers in
the ImageMap plugin.

* libgimp/gimp.[ch]: removed gimp_foo_version variables.
* libgimpbase/gimpenv.[ch]: added them here.
* app/sanity.c: added sanity_check_gimp() and abort if the libgimp
version gimp is compiled with is not exactly the same we encounter
at runtime.
2005-05-25 Nathan Summers <rock@gimp.org>
* app/sanity.c (sanity_check_filename_encoding): made the
G_FILENAME_ENCODING not or incorrectly set error message more
idiomatic.

* app/core/gimp-utils.[ch] (gimp_check_glib_version): removed this
function.
* app/sanity.c (sanity_check_glib): use glib_check_version()
instead and set required version to 2.6.0.

* configure.in: depend on GLib >= 2.4.5 and GTK+ >= 2.4.4.
* app/gui/gui.c: changed accordingly.
* app/sanity.c: ditto. Added check for GLib and put each check
into its own utility function. Enabled #if 0'ed check for
FreeType >= 6.2.7.

* app/widgets/gimpcursor.c
* app/widgets/gimpselectiondata.c
* app/widgets/gimpuimanager.c

* app/sanity.c (sanity_check_filename_encoding): try to convert
the result of gimp_directory() to UTF-8 and bail out with a
moderately helpful error message if this conversion fails. Works
around bug #150917. Also marked these strings for translation.
2004-08-07 Sven Neumann <sven@gimp.org>
* app/sanity.c: abort if the configured filename encoding can't be

* app/gui/gui.c: ... and do it here from gui_libs_init().
* app/main.c: changed accordingly.
2004-06-22 Sven Neumann <sven@gimp.org>
* app/widgets/gimpfiledialog.c (gimp_file_dialog_set_image): unset

* app/sanity.c: depend on gtk+ >= 2.4.1.
* app/widgets/gimpthumbbox.[ch]: changed gimp_thumb_box_set_uris()
to gimp_thumb_box_take_uris() since the function takes ownership
of the list,
* app/widgets/gimpfiledialog.c: changed accordingly. Removed code
that worked around a problem in gtk+ < 2.4.1.

disabled it until we figured if and how freetype causes some of
the DLL hell bugs.
* app/main.c (main): call it and abort if it fails.
* app/app_procs.[ch]: added app_gui_abort() so main.c doesn't
need to #include "gui/gui.h"
