Drop the glib-dbus dependency and port stuff to GDBus. Use it
unconditionally if not on Windows or OSX. It seels to work just like
before but I have no idea if everything is really correct.
This is a basic implementation of an OpenEXR loader. This
"infrastructure" is required for any further work. It consists of:
* The build system changes.
* A C wrapper around the OpenEXR library, which is necessary as it's not
possible to intermix GIMP's code with C++ code.
* A basic image loader. Chroma is not supported currently, and some
other weird files like multi-view files are unsupported. These can be
added when necessary. There is no UI, but it should be straightforward
to add new features like this on top of this work.
Without the dependencies of file-compressor (currently zlib, libbzip2
and liblzma), configure fails now. file-compressor is referenced in too
many places for its functionality to be optional.
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).

It will never hold high bit depths using JPEG compression, and nobody
is going to port it to layer groups and whatever either. Wolfgang
says it's obsolete, whoever needs to convert old files can use 2.8.
New configuration directory scheme, consistent across platforms, and
following standards.
UNIX platforms (except OSX): $XDG_CONFIG_HOME/GIMP/{GIMP_APP_VERSION}
Windows: %APPDATA%/GIMP/{GIMP_APP_VERSION}
OSX: NSApplicationSupportDirectory/GIMP/{GIMP_APP_VERSION}
This commit causes a compiler warning because string literals are of
type signed char, and we use a character out of the signed range in the
mimetype for xz. It can be fixed by changing the data type of the mime
string to (unsigned char *), and not using string literals, but that's
a bit too much for this commit.
And along with it a lot of stuff like the drawable preview cache, the
gegl tile manager backend, temporary gimp_gegl_buffer_foo() stuff, and
the remaining bits of performance.
The projection is in an evil semi-ported state which makes it work
ok-ish for stuff like layer moving, but absolutely unbearable for
painting, there is also an off-by-one rendering glitch at some zoom
levels.
gimpdir goes to ~/Library/Gimp/x.y
thumbnails go to ~/Library/Caches/org.freedesktop.thumbnails
The thumbnail location is not standardized yet, but is the only
location that makes sense. Also fix user install to search old
gimpdirs to migrate in both Library and the classic location.
Remove the obsolete CABON_CFLAGS from all makefiles.
