with other similar funcs, mainly copy-safe [i.e. you can use the same matrix as operand and result, saves lines in some already over-complicated code!]).

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):

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!

make RegisterBlendExtension_Fail a static func
u

|
C with gcc.
helps for finding unused functions and making functions static, also did some minor code cleanup.
|

which in this case caused NaN values in render lighting.
|
|
checked it for NULL after.
also made it more clear that some areas assume the pointer isnt null (remove redundant NULL checks).

BKE_utildefines is now unused but keep incase we want to add defines there later.

[Even | Smooth]
- Even preserves thickness but can give unsightly loops
- Smooth gives nicer shape but can give unsightly feather/spline mismatch for 'S' shapes created by beziers.
This is an example where smooth works much nicer.

- Make FFmpeg initialization called from creator, not from functions
which requires FFmpeg. Makes it easier to follow when initialization
should happen.
- Enable DNxHD codec. It was commented a while ago due to some strange
behavior on some platforms. Re-tested it on Linux and Windows and
it seemd to be working quite nice. Would let it be tested further,
if it wouldn't be stable enough, easy to comment it again.
- Make non-error messages from writeffmpeg.c printed only if ffmpeg
debug argument was passed to blender. Reduces console pollution
with messages which are not useful for general troubleshooting.
Error messages would still be printed to the console.
- Show FFmpeg error message when video stream failed to allocate.
makes it easier to understand what exactly is wrong from Blender
interface, no need to restart blender with FFmpeg debug flag and
check for console messages.
Used custom log callback for this which stores last error message
in static variable. This is not thread safe, but with current
design FFmpeg routines could not be called form several threads
anyway, so think it's fine solution/

var in math_rotation.c
|
|
|
|
rotation function called in many places so better to avoid iterations.
checked this function against the previous method using random rotation inputs and compared results, while this isnt exactly the same the results are very close and acceptable in both cases, also checked baking actions that the resulting FCurves are good and give matching rotations.

dist_squared_to_line_segment_v2() was returning the sqrt'd value in some cases.
also use int's for edge_inside_circle() rather then shorts since it was doing int/float/short conversions and we're now using int's for screen vars in more places.

was caused by feather edge going in a different direction to the mask edge - creating bowtie quads.

- replace (strcmp(vfont->name, FO_BUILTIN_NAME) == 0) with (BKE_vfont_is_builtin(vfont)).
- reduce some double promotions.
|
|
- don't overwrite the font path with "<builtin>" when the font file cant be found, it caused bad problems when loading files on someone elses systems when paths couldn't be found blender would silently clobber paths (tsk tsk).
- when fonts are freed their temp data is now freed too.
- assigning a new filepath to a font now refreshes the object data.
