* Revert 776bfa64a53191b and c3dad7953afccd4 (some X11 systems are doing
stupid things forcing me to do an extra check that completely breaks the
click type handling on other systems using the slightly changed
implementation from those commits - see T44278)
* Fix sample lines in Compositor+VSE
(And yes, this time I tested on both of my systems to make sure
everything is fine)

Missing color copy, noticed by @campbellbarton, thanks!
|
|
Either was some residue from the past or somebody didn't implement this in
the right way.
Also fixed memory leak in ED_space_clip_color_sample() caused by missing
image buffer release.

to push notifiers to redraw the node editor buttons.

OPERATOR_CANCELLED.
|
|
update some descriptions, others were removed and operators tagged as internal.
add a script to detect duplicate operator descriptions.
|
|
when running viewport operations with exec() rather then invoke(), perform the action immediately rather then using smoothview.
makes viewport operations usable from python scripts.

A new operator to alter the backdrop zoom level so that it fits fully within the node editor area, and centers the image.
Shortcut alt-home, as home is used for fitting stuff into the view everywhere.

sizeof() use in BLI_array.h
|
|
This is the first half of the commit, it's going to be reviewed further.
It also depends on other work in node drawing (to not reshuffle order on
every select/activate).
At least it works quite nice for the shortcuts shift [ and shift ]

PyNodes opens up the node system in Blender to scripters and adds a number of UI-level improvements.
=== Dynamic node type registration ===
Node types can now be added at runtime, using the RNA registration mechanism from python. This enables addons such as render engines to create a complete user interface with nodes.
Examples of how such nodes can be defined can be found in my personal wiki docs atm [1] and as a script template in release/scripts/templates_py/custom_nodes.py [2].
=== Node group improvements ===
Each node editor now has a tree history of edited node groups, which allows opening and editing nested node groups. The node editor also supports pinning now, so that different spaces can be used to edit different node groups simultaneously. For more ramblings and rationale see (really old) blog post on code.blender.org [3].
The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout. Internal sockets can be exposed from a group by either connecting to the extension sockets in input/output nodes (shown as empty circle) or by adding sockets from the node property bar in the "Interface" panel. Further details such as the socket name can also be changed there.

This makes it so sample line (for all image editor, sequencer and compositor)
displaying managed color for byte buffers as well. It was simply not implemented
before.

This commit makes BKE_image_acquire_ibuf referencing result, which means once
some area requested for image buffer, it'll be guaranteed this buffer wouldn't
be freed by image signal.
To de-reference buffer BKE_image_release_ibuf should now always be used.
To make referencing working correct we can not rely on result of
image_get_ibuf_threadsafe called outside from thread lock. This is so because
we need to guarantee getting image buffer from list of loaded buffers and it's
referencing happens atomic. Without lock here it is possible that between call
of image_get_ibuf_threadsafe and referencing the buffer IMA_SIGNAL_FREE would
be called. Image signal handling too is blocking now to prevent such a
situation.
Threads are locking by spinlock, which are faster than mutexes. There were some
slowdown reports in the past about render slowdown when using OSX on Xeon CPU.
It shouldn't happen with spin locks, but more tests on different hardware would
be really welcome. So far can not see speed regressions on own computers.
This commit also removes BKE_image_get_ibuf, because it was not so intuitive
when get_ibuf and acquire_ibuf should be used.
Thanks to Ton and Brecht for discussion/review :)

As it turned out, the node space was the only place we have the option to sample the backdrop buffer RGB, but not the zed.
This code is copied from image space.
Now one can use the viewer node and sample the depth while looking at the color buffer (so Map Range Node works even better)
Patch written during BlenderPRO 2012, Brasília ;)

Regressions since color picking support from background image.

Replace old color pipeline which was supporting linear/sRGB color spaces
only with OpenColorIO-based pipeline.
This introduces two configurable color spaces:
- Input color space for images and movie clips. This space is used to convert
images/movies from color space in which file is saved to Blender's linear
space (for float images, byte images are not internally converted, only input
space is stored for such images and used later).
This setting could be found in image/clip data block settings.
- Display color space which defines space in which particular display is working.
This settings could be found in scene's Color Management panel.
When render result is being displayed on the screen, apart from converting image
to display space, some additional conversions could happen.
This conversions are:
- View, which defines tone curve applying before display transformation.
These are different ways to view the image on the same display device.
For example it could be used to emulate film view on sRGB display.
- Exposure affects on image exposure before tone map is applied.
- Gamma is post-display gamma correction, could be used to match particular
display gamma.
- RGB curves are user-defined curves which are applying before display
transformation, could be used for different purposes.
All this settings by default are only applying on render result and does not
affect on other images. If some particular image needs to be affected by this
transformation, "View as Render" setting of image data block should be set to
truth. Movie clips are always affected by all display transformations.
This commit also introduces configurable color space in which sequencer is
working. This setting could be found in scene's Color Management panel and
it should be used if such stuff as grading needs to be done in color space
different from sRGB (i.e. when Film view on sRGB display is use, using VD16
space as sequencer's internal space would make grading working in space
which is close to the space using for display).
Some technical notes:
- Image buffer's float buffer is now always in linear space, even if it was
created from 16bit byte images.
- Space of byte buffer is stored in image buffer's rect_colorspace property.
- Profile of image buffer was removed since it's not longer meaningful.
- OpenGL and GLSL is supposed to always work in sRGB space. It is possible
to support other spaces, but it's quite large project which isn't so
much important.
- Legacy Color Management option disabled is emulated by using None display.
It could have some regressions, but there's no clear way to avoid them.
- If OpenColorIO is disabled on build time, it should make blender behaving
in the same way as previous release with color management enabled.
More details could be found at this page (more details would be added soon):

- pass wire color to camera draw_viewport_object_reconstruction() rather then getting the theme color directly.
this makes a change where selection color wont be used for unselected cameras (which IMHO is better, drawing selected wire color on nonselected cameras was confusing).
- use rgb_uchar_to_float()

image editor or node space.
|
|
also the compositor bounds (used for scroll bars), were only calculated when pressing the home key in 2.63, how this is updated on draw
|
|
border zoom, view selected, view all.
|
|
- when single (non frame) node selected, dont zoom in, just pan.
- only reset the background when pressing home key
|
|
- dupligroup now only selects objects with dupligroup enabled.
- selected onjects are skipped, this way and undo push wont happen if no new objects are selected.
also minor edits to node view all/selected

transformed, but in fact its parents parent could still be getting transformed still, also, the order of initializing transform data made this check unreliable.
fix for mingw broke from one of my own commits, changing header order fixes.
