Least-squares fitting parameters were stored in a fixed size array, causing a
buffer overflow depending on the number of input points.
Problem report with a .blend file to reproduce the issue and a bugfix patch by
christiankrupa and jensverwiebe on IRC, thanks a lot!
Many thanks also to Bastien Montagne for forwarding the problem report by email.
These parameters specify a distance in Blender units, so PROP_DISTANCE is more appropriate.
Suggested by Bastien Montagne through personal communications, thanks!
Added a label to guide users to line style settings in the Render Layers context
(in line with the similar labels found in the Cloth and Soft Body modifier panels),
so that Freestyle options per render layer can be more easily found.
Custom implementation for resizing (GHOST_SizerWin32)
Some things still don't work:
* esc cancel
* max windows size
* aero (sizing) snap on win7
hbrBackground = 0 to disable clear screen.
Thanks to dfelinto for help in finding of root cause.
- Add and subtract effects will now affect on only RGB channels,
and alpha of first input is used as an alpha for the result.
Also solved creepyness with straight->premul->straight conversion
in byte versions of add/subtract.
- Solved issue with multiply modifier, which lead to white*white
not being white (was off by 1.0/255) due to wrong optimization
of division by 255 with shr by 8.
According to Ton this issue goes back to 2000!
This fixes#34811: Wrong result of add/subtract effects
low roughness and same index of refraction.
Problem was bad float precision due to low roughness, which caused the pdf for
the different closures to not match properly.
Also workaround a nasty bug, where unregistered py classes remain listed in relevant __subclasses__() calls, which would lead to crash with python addons i18n tools (main translation was not affected, as messages extracting tools are executed in a brand new "factory startup" Blender ;) ).
- replace ED_operator_rigidbody_add_poll with ED_operator_object_active_editable_mesh
- replace ED_operator_rigidbody_active_poll with ED_operator_scene_editable for operators that use the entire selection.
- remove rigid-body from objects that are converted from meshes to curves, while this isnt crashing it is confusing to see in the UI.
- add checks so rigid-body operators only return FINISHED when they make some changes to the scene.
- remove (scene == NULL) checks, poll already catches these.
A crash in the Freestyle renderer was reported by Ton on IRC with a stack trace
below. Note that #2 is in Freestyle, whereas #1 is in the compositor. The problem
was observed in a debug build on OS X 10.7 (gcc 4.2, openmp disabled, no llvm).

Apparently a name conflict between the two Blender modules is taking place.
The present commit hence intends to address it by putting all the Freestyle C++
classes in the namespace 'Freestyle'. This revision will also prevent potential
name conflicts with other Blender modules in the future.
Special thanks to Lukas Toenne for the help with C++ namespace.
* Make masking depend on texture mode only if there's an actual texture
present
* New stroke system uses diameter to calculate stroke spacing, while old
texture painting brushes and system used radius. So divide spacing of
brushes in old files to half. Since I expect trunk users to have already
adapted this, I do this for an old subversion of blender.
- Get rid of rotation matrix parameterization,
use angle-axis instead.
Also Joined rotation and translation into a
single parameter block.
This made minimization go significantly faster,
like 1.3x times in average.
- Fix first camera when bundling. This is to
address orientation ambiguity.
Reconstruction result could still vary in
size, but that's another issue to be addressed
later.
Additional change:
Split EuclideanBundleCommonIntrinsics into
smaller functions, so it's now a bit easier
to follow.
* Pressing x or y to scale overlay immediately presents visual feedback
instead of requiring mouse motion
* Hide the ovelay icon when stencil is active since you can't deactivate
then.
