Create all display filters with "color-config" and "color-managed"
parameters set, not only the automatically added color management
display filter. This way we don't only support removing and adding the
filter again, but also support potential other color management
modules.
so the automatically saved timestamped presets don't fill up with
duplicates of identical settings. The default impl considers them
different because of their timestamps.
Adds an icon-pixbuf property to GimpViewable that is used for a default
implementation of new_pixbuf.
Extend gimp_icon_picker to allow the user to pick non-stock icons for tool
presets (or any other class derived from GimpViewable). Icons can come
from any file GdkPixbuf can load or from image data on the clipboard.
Save the "right-docks-position" as negative value in pixels from the
right window border. Change the image window restoring code to
interpret negative values like that, but keep the meaning of positive
values for compatibility with existing sessionrc files.
gimp_docked_iface_get_aux_info(): always save the button bar state,
not only if it is "false" because we cannot know the default value any
longer (the button bar visibility used to always default to "true", so
saving only a non-default "false" was fine).
Applying a preset overwrites all the tool option's properties, also
temporarily its name. This name change gets auto-synced with the
option's text proxy object which also inherits from GimpObject and has
a name. Make sure we don't queue that name change for being applied to
the text layer's text object, because that code only handles
properties of GimpText itself.
Remove plain .gz .bz2 .xz from the extensions the file-compressor
plug-in registers, and make sure is only ends up in "save_procs", so
at least "exporting" to foo.xcf.gz is not possible any longer. With
some effort, one can still "save" to foo.png.gz tho, but it's much
harder now.
file_procedure_in_group(): consider "file-uri-save" to be in both the
SAVE and the EXPORT groups.
gimp_plug_in_manager_register_save_handler(): allow a procedure to be
in both "save_procs" and "export_procs".
The logic in the file save/export dialog checks uri prefixes and
extensions just fine, so nothing bad seems to happen from this change,
I hope...
ROUND() is consistent only on positive values, and bad rounding
creates an offset when negative values are involved. Introduce
SIGNED_ROUND() and use it in gimprectangletool.c. It should probably
be used in much more places.
Calling FcConfigSetCurrent() with NULL is just broken, it almost
immediately dereferences the passed pointer. Apparently this line
is executed seldom, otherwise we'd see way more crashes in this place.
Just use FcInitReinitialize() which exists for the very purpose of
reinitializing the fontconfig library.
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).

Update the migration function so that it does not apply any restriction
on files where no explicit migration rules are set (for instance binary
files where no proper migration rules by regexp is possible).
