Now it's a bit more robust, tagging images with profiles when they're loaded,
which then get interpreted later on by conversion functions. Just Linear RGB
and sRGB profiles at the moment, same as before.
This commit fixes Martin's problem with EXRs and Multilayer images loading/
saving too dark, and it also makes the sequence editor work correctly with it too.
Also fixes:
[#19647] gamma correction with color management is reset when resetting Curve
[#19454] 2.5: Dither does not work when Color management is enabled
- scene.render_data.frame_path(frame=num), returns the output path for rending images of video.
- scene.render_data.file_extension, readonly attribute, gives the extension ".jpg", ".mov" etc
- player support was guessing names, use the above functions to get the actual names used, accounting for #'s replacing numbers.
* Added 'active node' panel for the Nodes Editor. This panel, in the NKEY region, shows the settings for the active node. Included in this panel is a field used for editing the unique-name of the node too.
* Fixed a number of uninitialised vars warnings that I missed in previous commit...
* Convert all code to use new functions.
* Branch maintainers may want to skip this commit, and run this
conversion script instead, if they use a lot of math functions
in new code:
http://www.pasteall.org/9052/python
Still a few quirks, including redraw issues on multilayer image input nodes, but it's pretty much there.
Would also be good to wrap the input/output sockets, too, will check on it.
This fixes bug [#19740] INPUT NODE: Cannot load images / motion pictures
* Compo node backdrop works again.
* Compo node previews and backdrop now get correct color management
float to byte conversion.
* Compo nodes got unecessarily recalculated while moving nodes.
* Fix compo node viewer nodes not getting activated correctly.
* Main compo node preview render computations are now outside of
mutex lock, so better for multithreading.
* Tex node outputs did not work in some files loaded from 2.4.
* Change RNA updates to take into account groups that may be shared
between multiple node trees.
Since bli_threads.h now includes pthreads directly, we need to had instructions in SConscripts everywhere for proper include path.
Frankly, I feel like this should be done in a global manner and not in a per lib fashion, but that is for another day.
This commit also fixes more missing properties
* Rendering twice or more could crash layer/pass buttons.
* Compositing would crash while drawing the image.
* Rendering animations could also crash drawing the image.
* Compositing could crash
* Starting to rendering while preview render / compo was
still running could crash.
* Exiting while rendering an animation would not abort the
renderer properly, making Blender seemingly freeze.
* Fixes theoretically possible issue with setting malloc
lock with nested threads.
* Drawing previews inside nodes could crash when those nodes
were being rendered at the same time.
There's more crashes, manipulating the scene data or undo can
still crash, this commit only focuses on making sure the image
buffer and render result access is thread safe.
Implementation:
* Rather than assuming the render result does not get freed
during render, which seems to be quite difficult to do given
that e.g. the compositor is allowed to change the size of
the buffer or output different passes, the render result is
now protected with a read/write mutex.
* The read/write mutex allows multiple readers (and pixel
writers) at the same time, but only allows one writer to
manipulate the data structure.
* Added BKE_image_acquire_ibuf/BKE_image_release_ibuf to access
images being rendered, cases where this is not needed (most
code) can still use BKE_image_get_ibuf.
* The job manager now allows only one rendering job at the same
time, rather than the G.rendering check which was not reliable.
Editors Modules
* render/ module added in editors, moved the preview render code there and
also shading related operators.
* physics/ module made more consistent with other modules. renaming files,
making a single physics_ops.c for operators and keymaps. Also move all
particle related operators here now.
* space_buttons/ now should have only operators relevant to the buttons
specificially.
Updates & Notifiers
* Material/Texture/World/Lamp can now be passed to DAG_id_flush_update,
which will go back to a callback in editors. Eventually these should
be in the depsgraph itself, but for now this gives a unified call for
doing updates.
* GLSL materials are now refreshed on changes. There's still various
cases missing,
* Preview icons now hook into this system, solving various update cases
that were missed before.
* Also fixes issue in my last commit, where some preview would not render,
problem is avoided in the new system.
Icon Rendering
* On systems with support for non-power of two textures, an OpenGL texture
is now used instead of glDrawPixels. This avoids problems with icons get
clipped on region borders. On my Linux desktop, this gives an 1.1x speedup,
and on my Mac laptop a 2.3x speedup overall in redrawing the full window,
with the default setup. The glDrawPixels implementation on Mac seems to
have a lot of overhread.
* Preview icons are now drawn using proper premul alpha, and never faded so
you can see them clearly.
* Also tried to fix issue with texture node preview rendering, globals can't
be used with threads reliably.
Added RGB space distance matte Node
Added HSV color matte Node
Fixed Image difference matte Node to use image differences instead of RGB space distance
Fixed luminance node for low end values being read wrong
Fixed CMP_util copy/swap functions not accounting for all channels
Fixed UI for difference matte Node
Added RNA for new nodes
* bring back 'player' libtype, after investigation with ideasman.
scons/mingw works nicely, for some reason msvc fails to link still, will look further into it.
Delegates now receive a TexParams* instead of float *coords. This gives texture nodes access to dxt, dyt, cfra as well as coords. This fixes the time node and allows nice sampling to be implemented.
* Exposed Tex.use_nodes, Tex.nodetree, MTex.which_output in RNA
* Added node controls to texture buttons (Use Nodes and Use Output)
* Made new texture outputs have unique names by default, though unique names still aren't required.
Note: The preview window in the texture buttons only takes which_output into account when in "material" mode, and in the material half of "both" mode; the plain texture display ignores the user's output choice.
This is because ED_preview_draw draws a Tex* and not an MTex* -- still some work to do here.

* ID blocks can now get RNA properties defined from python, e.g.:
bpy.types.Scene.BoolProperty(..)
* RNA structs/functions/properties can now get pointers duplicated
(mostly strings), since we can't point to some static string then.
* Added ExtensionRNA struct to add into *Type structs for subclassing,
is a bit more compact than defining the 4 variables each time.
Only disadvantage is it requires including RNA in more places.
- 1st stage: Linear Workflow
This implements automatic linear workflow in Blender's renderer. With the
new Colour Management option on in the Render buttons, all inputs to the
renderer and compositor are converted to linear colour space before
rendering, and gamma corrected afterwards. In essence, this makes all
manual gamma correction with nodes, etc unnecessary, since it's done
automatically through the pipeline.
It's all explained much better in the notes/doc here, so please have a look:
http://wiki.blender.org/index.php/Dev:Source/Blender/Architecture/Colour_Management
And an example of the sort of difference it makes:
http://mke3.net/blender/devel/rendering/b25_colormanagement_test01.jpg
This also enables Colour Management in the default B.blend, and changes the
default lamp falloff to inverse square, which is more correct, and much
easier to use now it's all gamma corrected properly.
Next step is to look into profiles/soft proofing for the compositor.
Thanks to brecht for reviewing and fixing some oversights!
Composite "Map UV" node was using false UVs (0,0) from neighbouring
pixels when those pixels were not rendered (or have no UV).
This commit checks for each neighbour sample it takes if the UV was
correctly set. Solves bad errors on edges of UV maps. With FSA even
totally smooth. :)

Notes:
* Game and sequencer RNA, and sequencer header are now out of date
a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
not needed anymore.
* Fix "duplicate strip" always increase the user count for ipo.
* IPO pinning on sequencer strips was lost during Undo.
Third transparent shadow bug... this time it's a Material Node, which
has mirror + transp-shadow on, and when it traces its own material it
enters an eternal loop...
Raytracing + shading + materialnode combo really needs work!
1) Remove WITH_FREETYPE2 from code, so now blender always need freetype2
2) Remove the old bmfont
3) Remove ftfont and bFTGL library
4) Implement a new BLF_draw_default function for place that still need/use
the old BMF api.
I try to update both, scons and cmake, but I only can test with make, so
hope all work fine.
MSVC is broken, but I don't have Windows, things to search and fix are
any reference to WITH_FREETYPE2, FTGL and BMFONT (take in care that
blenkernel also have a BKE_bmfont.h, this don't have anything to do with bmfont).
Always have to link/include the freetype2 library
Remove any reference to libbmfont
Remove any reference to libftfont
Remove any reference to libbftgl (or libbFTGL)
