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.

Thanks to Xavier Thomas, Lukas Toene for initial work on OpenColorIO
integration and to Brecht van Lommel for some further development and code/
usecase review!
Before this overlay would happen only for defined rectangle area,
now it's possible to show current / reference frames only, which
makes it possible to do more real slit view involving even displaying
frames on different monitors.
Still some work need to be done to clean interface up and support
displaying color information for reference shot.
space works again
This commit restores the support for using Grease Pencil in the Sequence Editor
image preview region, making it possible to scribble on footage for review
purposes again. Due to internal changes in how the Sequencer handles the image
drawing for this stuff (i.e. it is now fully based on View2D instead of trying
to implement its own little crazy offset+zoom stuff), a lot of the old code for
handling those offsets is no longer needed. Instead, one of the "standard" cases
is now used, and works quite well.
Bugfixes:
* View-space Grease Pencil drawing was done in wrong place (before view2d
restore)
* Grease Pencil entry in RNA had wrong/missing type
Credits:
* DingTo - initial patch/attempt at restoring support
* Aligorith - solved the "offset problems"
* Remove some non used *_button_register functions, panels are done in python.
* Remove do_node_region_buttons, was not used anymore.
Fix:
* Only show Grease Pencil panel in the Node editor, when there is a valid nodetree.
- editmesh smooth & subdivide were using old mirror axis flag still.
- removed colbits from outliner and object code.
- commented some other parts of the code which access deprecated members and aren't called anywhere.
Improved waveform drawing in the sequencer.
* Drawing the waveform of a sequencer strip is now independent from whether the sound is cached or not.
* Improved drawing of the waveform in the sequencer (especially speed!).
* Making it possible to vertically zoom more in the sequencer to better see the waveform for lipsync.
* Fixed a bug which crashed blender on loading a sound file via ffmpeg.
animation editors (DopeSheet, Graph Editor, NLA, Sequencer) ==
=== Usage Notes ===
In animation editors, marker operators will only be considered while
the mouse is hovering near/over the horizontal scrollbar (i.e. where
the markers usually appear). That means, in order to do something to
the markers, just position your cursor in line with the row of
markers, and then use the same hotkeys you'd use in the TimeLine (so,
unlike in 2.4x, no more need to hold down extra modifier keys for this
case). In the TimeLine, nothing changes, so you don't need to worry
about mouse placement there :)
=== Technical Details ===
Since early 2.5 versions, this functionality has been disabled, as the
markers were always getting evaluated first, and hence "swallowing"
all the events before the editor's own keymaps could access them.
In order to get this working again, I've had to give every marker
operator a "wrapper" invoke callback which performs some checking to
ensure that the mouse is close to the markers (vertically) before the
operator will try to be run. This wrapper also makes sure that once
the operator has finished running, that if it didn't manage to do
anything, then the editor's own keymaps get to have a go.
The vertical tolerance used is currently 30 pixels (as was used for
the borderselect operator).
=== Other Assorted Changes ===
* Gave marker operators dependent on having selected markers to
operate on suitable poll() callbacks. These new poll callbacks ensure
that there are selected markers for the operator to operate on,
further cutting down the number of places where markers may override
standard hotkeys (and avoiding calls to the wrappers too)
* Simplified some of the selection code
* Made some formatting tweaks for consistency, and in one case so that
my text editor's function-list display doesn't get confused
Dropping in image/movie/sound strips was broken; it dropped
things in wrong location (frame 0), and without giving images proper
length.
The file path setting code for the operators here is complex...
- Okey sets the border in the display.
- Okey resets the frame offset in the sequencer timeline.
- ghost icon in the header can enable/disable.
- frame offset can be relative or absolute (lock icon)
Not very happy that this commit adds a call to BKE_animsys_evaluate_animdata(scene, ...) in do_build_seq_array_recursively()
without this the offset frames dont have fcurves applied.
Though we will need something like this for prefetch frames to work too.
path -> filepath (for rna and operators, as agreed on with elubie)
path -> data_path (for windowmanager context functions, this was alredy used in many places)
Added ability to drag images and movies directly onto objects to assign them as textures.
You can drag them from the file browser, directly from the OS or even from other apps. Here's a video to demonstrate:
http://www.youtube.com/watch?v=fGe2U8F_JvE
Ton wanted to show me how to add it, but he ended up doing almost all of the coding himself ;)
Ton/Matt: Dropping a text file in the Text Editor fails for some reason. It aught to work - probably a keymap conflict of some sorts?
Only source/blender/editors/ dir, should not give errors on different platforms
Only removing: UI_*.h, ED_*.h, WM_*.h, DNA_*.h, IMB_*.h, RNA_*.h, PIL_*.h
* Zoom and Pan should work now (thanks Aligorith for reviewing)
* mostly removed ancient drawing code
* Fit preview in Window still has issue, HOME key in preview area should be working though
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
There are calls to define drag-able images, ID blocks, RNA paths,
file paths, and so on. By default you drag an icon, exceptionally
an ImBuf
- Drag items are registered centrally in the WM, it allows more drag
items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts
the mouse event to an EVT_DROP type. This event then gets the full
drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps
you can make a "drop map" this way, which become 'drop map handlers'
in the queues.
- next to that the UI kit handles some common button types (like
accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
- poll() = check if the event drag data is relevant for this box
- copy() = fill in custom properties in the dropbox to initialize
an operator
- The dropbox handler then calls its standard Operator with its
dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit
on mouse-over. In case the icon is a button or UI element too (most
cases), the drag-able feature will make the item react to
mouse-release instead of mouse-press.
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works
too. I've added code that passes on mousemoves and clicks to other
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an
Image ID... keep this in mind. Sequencer for example wants paths to
be dropped, textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're
part of the UI and editor design (= how we want an editor to work), and
not default offered configurable like keymaps.
- At the moment only one item can be dragged at a time. This is for
several reasons.... For one, Blender doesn't have a well defined
uniform way to define "what is selected" (files, outliner items, etc).
Secondly there's potential conflicts on what todo when you drop mixed
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip,
should be represented in filewindow as a single sequence anyway.
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it
could show the operator as a sort of menu, allowing arrow or scrollwheel
to choose. For time being I'd prefer to try to design a singular drop
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that
detects an object (type) under cursor, so a drag item's option can be
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled,
while WM event code tried same. Added new OPERATOR_HANDLED flag for this.
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
(for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review...
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS
into Blender window. I've noticed this code is unfinished for Macs, but
seems to be complete for Windows. Needs test... currently, an external
drop event will print in console when succesfully delivered to Blender's WM.
these expose the final start and end after offsets are applied. when set this is like grabbing the handle and moving it.
* made swapping strips shuffle effects and check for overlap.
