For some reason recent change in avoiding non-aligned eigen vectors
was behaving differently for cmake and scons. Made it a bit different
now by storing scalars. This is more robust approach anyway, because
it's not really guaranteed Mat.col() gives a pointer inside data,
depending on column-major vs. row-major storage.
This is to be backported to 2.74 branch.
It was only happening on 32bit platforms because of alignment
differences when allocating class.
Now got rid of copy of eigen matricies stored by value in the
residual block which solves aligment issues and should also
give some unmeasurable speedup.
Main purpose of this is to bring new gflags library which is more likely
to have a fix for undefined order of static variables initialization and
also to bring new glog where some compilation error are fixed (which are
only visible with more strict checks with clang and c++11 enabled).
The main idea is to share as much code between cases when feature-full built
is done and only logging is needed, so all the defines and include directories
are guaranteed to be the same.
This would hopefully make it so MinGW compilation is all happy about Cycles
logging for both CMake and SCons.
Couple of issues:
- Fist/last frame calculation was wrong
- Keyframe selection might silently fail leading to unpredictable math
errors all over the place. Now if keyframe selection fails solver wouldn't
run.
This is mainly to address old issue when one need to have SDL library installed
in order to use our official builds. Some hip distros already installs SDL,
but it's not quite the same across all the variety of the distros.
We also now switching to SDL-2.0, most of the distros have it in repositories
already, so it shouldn't be huge deal to install it if needed.

This was never ported to a new tracking pipeline and now it's done using
FrameAccessor::Transform routines. Quite striaghtforward, but i've changed
order of grayscale conversion in blender side with call of transform callback.
This way it's much easier to perform rescaling in libmv side.
The title actually tells it all, this commit switches Blender to use the new
autotrack API from Libmv.
From the user point of view it means that prediction model is now used when
tracking which gives really nice results.
All the other changes are not really visible for users, those are just frame
accessors, caches and so for the new API.
This starts the creating the new AutoTrack API. The new API will
make it possible for libmv to do full autotracking, including
predictive tracking and also support multiple motion models (3D
planes etc).
The first goal (not in this patch) is to convert Blender to use
the new API without adding any new functionality.
This API currently contanins:
- Frame accessor to access frames which are stored in Blender side.
- New Tracks implementation
- New Reconstruction implementation
Currently this API only tested on doing the same frame-to-frame
tracking as the old API allowed to do. But it also supports now
predictive tracking which is based on the Kalman filter.
The ones in extern/glew-es have been changed to NOTE instead of XXX
GHOST_ContextEGL.cpp: It really does seem that it is not possible to query the swap interval using EGL
GHOST_WidnowCocoa.h: The comment referring to Carbon is clearly out of date, so I removed it.
math_geom.c: The node about not using tmax again is correct, but the code is kept for a future maintainer who will need to know how to compute it if they modify that code.
paint_image_proj.c (2698): The question about integer truncation does not appear to have been resolved. It still seems to be an incorrectly implementation of rounding (I'd suggest using the round function instead of this hack).
We on'don't really support 10.5 anymore for my knowledge and in any case
the defined symbol was never checked in the sources, so this workaround
was basically doing nothing for quite some time now.
This makes headers a bit less clean (with the anonymous structs
mainly and headers inclusion from another header.
Makes compilation with clang a bit less noisy.
Update lzo library due to security issue
Update lzo to latest version. This fixes a security issue (reported in T41974)
This also fixes some (false-positive) valgrind warnings.

This commit makes it possible to use Glog library for the debug logging.
For now only possible when using CMake and in order to use the logging
the WITH_CYCLES_LOGGING configuration variable is to be enabled.
When this option is not enabled or when using Scons there's no difference
in Cycles behavior at all, when using logging and no output to the console
impact is gonna to be minimal.
This is done in order to make it possible to have debug logging persistent
in code (without need to add it when troubleshooting some bug and removing
it afterwards).
For now actual logging is not placed yet, only all the functions needed for
the logging are written and so.
This would give some performance boost when solving huge scenes,
amount of boost depends on particular scene.
For now enable all of the specializations, in the future we might
add some local patches and restrict only unneeded ones.
The issue was caused by the wrong attributes maps in certain
circumstances after union intersections.
Namely issue might have happen when more than one iteration of
union was happening and it was caused by the fact that new faces
might be allocated on the same address as freed face from the
old mesh.
Didn't find a nicer fix for this apart from correcting the whole
attributes map after each union step.
We could try removing attributes for the meshes which are getting
deleted, but in asymptotic it's gonna to give exactly the same
complexity as the current approach.
This assert happens all the time for character physics in debug mode.
In release mode, the assert is skipped but the code is still incorrect
although it does not cause any crash strangely.
