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!
- optionally display the histogram as lines (not filled areas).
- expand the enum for faster access.
- keep the sample line displayed after doing the line sample (running again clears).
added some missing functions too - which are not used yep but should be there for api completeness.
* CDDM_set_mloop
* CDDM_set_mpoly
* BLI_mempool_count
* Some cleanup, removed references to already deleted *_header.c files.
* Marked SpaceScript as deprecated and removed header. Will keep space for now though, as some script operators are there and Campbell might want to re-use the space later.

mostly because of the recent changes in normalmap channels,
so users can adopt old bakes quickly.
though they might aswell prove useful in other situations.
Implementation note: this was done by giving each Render a slot number,
and for every slot a new Render will be created. Not sure if this is
ideal, but it ensures that all passes, render info, etc are separate so
you can also compare render layers and passes, in 2.4x only whatever it
was currently displaying was backed up.
* Added a generic 'histogram' ui control, currently available in new image editor
'scopes' region (shortcut P). Shows the histogram of the currently viewed image.
It's a baby step in unifying the functionality and code from the sequence editor,
so eventually we can migrate the sequence preview to the image editor too,
like compositor.
Still a couple of rough edges to tweak, regarding when it updates. Also would
be very nice to have this region as a partially transparent overlapping region...
* Grease Pencil works again from Image Editor now. For now, the GPencil datablock is linked to the Image Editor space, but this can be changed if need be.
* Made Grease Pencil hotkeys into a separate Grease Pencil keymap, which can get included automagically like for frames/ui/v2d/etc. by supplying ED_KEYMAP_GPENCIL as part of st->keymapflag
* Temporarily restored the nasty hack to make View2D-aligned sketches in Image Editor to use OpenGL lines only. I still dunno why this doesn't work normally.
(Probably related is that strokes are not visible when there's no image visible atm).
* Fix buttons jumping around when resizing and zoom. Part of this was
adding a tiny a 0.001f offset in UI_view2d_view_ortho, otherwise the
rounding is unpredictable (used to be 0.375f, but that was disabled).
* Fix various issues with zooming, panning panels. V2D_LOCKOFS_X/Y is
now taken into account in more places in the view2d code, to avoid
zooming into the center or panning out of the view.
* Remove "Free" align mode in buttons window (it's not really useful).
* View3D/Graph/Image editors now use the same PanelType system as the
buttons window, means some deprecated panel code could be removed.
* Some small visual tweaks for panels.
* View 2D Reset operator (Home key), to reset zoom and panning for panels.
* Added argument to set number buttons as sliders (slider=True for itemR).
* Ignore labels for button alignment (doesn't look right).
* Fix some use of context.main in py scripts, should get data from active
object instead.
* Fix autotexspace -> auto_texspace in py script.
- use select as a suffix eg UV_OT_loop_select -> UV_OT_select_loop
- Each select all operator was using slightly different wording...
select_all, deselect_all, de_select_all, select_de_select_all -> select_all_toggle
- selection -> select
- POSE_OT_select_connected -> POSE_OT_select_linked to match other operators
- NODE_OT_delete_selection -> NODE_OT_delete since its not used in other operators
- ANIM_OT_previewrange_define -> ANIM_OT_previewrange_set to match other operators
- NODE_OT_fit_all -> NODE_OT_view_all to match other operators
- View2D_OT_* -> VIEW2D_OT_* to match VIEW3D
- View2D_OT_view_downscroll -> VIEW2D_OT_scroll_down more logical
- removed MARKER_OT_mouseselect_extend and made extend a boolean property of MARKER_OT_mouseselect
- MARKER_OT_mouseselect -> MARKER_OT_select
- GROUP_OT_group_remove -> GROUP_OT_objects_remove more logical since its removing objects from groups
- MESH_OT_removedoublesflag -> MESH_OT_remove_doubles
- redundant words MESH_OT_split_mesh -> MESH_OT_split, OBJECT_OT_object_delete -> OBJECT_OT_delete
renamed selection operator properties
extend_select -> extend
column_select -> column
select_children_only -> children_only
... Since these are all in the context of selection operators there is no need for the extra 'select' in the property name.

Useful goodies: most buttons for Image window back.
Not every button works! But what you can do:
- press Nkey to show/hide options
- use curves, with realtime updating
- image properties panel, load, browsing layers,
setting types
- paint panel
- plus new paint color picker panel! (why it wasn't
there in 2.4x is probably obvious, but now it can!)
Hrm... radial control should be added here too, and a nice
paint size cursor?
* Added notifier for edited images.
* Fix main region emboss drawing when showing render.
* Don't go fullscreen with fileselect for now to work
around context getting lost, so open/replace works.
* Save operators are more complete now, but still lack
confirmation and choosing image type.
* Pack operators work correctly now (but not unpack).
* Setting white/black point for curves.
* Time cursor for record composite.

The file select operators have context issues still. They need
to get the image space in the context on exec() but it's not
there currently, not sure how to solve that yet.
Also added name parameter to uiMenuItemEnumO, and fixed "mute"
argument in ED_update_for_newframe calls in fluidsim bake.
still is mirror transform. This commits adds the remaining operators:
* UV mapping operators (U key menu): cube, sphere, cylinder, etc.
* Hide/Show operators.
And solves most XXX's, including:
* Fix bad includes and calls into space image.
* Aspect ratio correction.
* Create UVs if they don't exist yet on unwrap.
* Assign image to UVs.
* Drawing proportional edit circle.
* UV Editor Transform, translate, rotate, scale, live unwrap, snap, gesture,
etc work.
* Also for selection operators, used OPERATOR_FINISHED|OPERATOR_PASS_THROUGH
instead of just OPERATOR_PASS_THROUGH to make gestures work, seems more
correct to me.
Organized as follows:
uvedit/
uv editing related code
uvedit_draw.c: drawing code
uvedit_ops.c: operators, just a few done
uvedit_unwrap_ops.c: will be operators for unwrapping
uvedit_paramatrizer.c: lscm/abf/stretch/pack
space_image/
space_image.c: registration and common getter/setters
image_draw.c: drawing code, mostly functional
image_panels.c: panels, all commented out
image_render.c: render callbacks, non functional
image_ops.c: operators, only view navigation done
image_header.c: header, menus mostly done but missing buttons
Notes:
* Header menus consist only of Operator and RNA buttons, if they
are not implemented they're displayed grayed out. Ideally the full
header could work like this, but std_libbuttons looks problematic.
* Started using view2d code more than the old code, but for now it
still does own view2d management due to some very specific
requirements that the image window has. The drawing code however
is more clear hopefully, it only uses view2d, and there is no
switching between 'p' and 'f' view2d's anymore, it is always 'f'.
* In order to make uvedit operators more independent I move some
image space settings to scene toolsettings, and the current image
and its buffer is in the context. Especially sync selection and
select mode belonged there anyway as this cannot work correct with
different spaces having different settings anyway.
* Image paint is not back yet, did not want to put that together with
uvedit because there's really no code sharing.. perhaps vertex paint,
image paint and sculpt would be good to have in one module to share
brush code, partial redraw, etc better.
