Export multiple frames to separate files.

Frame 20 with mentioned filename `name` is exported to `name020.obj`
It should be modified to exclude cases when a single frame is being
exported to avoid overwriting what the user intended to name it.

Also a filter is added to include only OB_MESH type objects for export.

The limits on frames can be changed, the current limits are like this:
Let's say unknowingly, the user selects the maximum 1000 frames & every
file is 1 MB in size. That will quickly fill up 1 GB on the disk.
More frames add to this risk.

This fixes the behavior of `ctrl+F` and `shift+F` to control the angle
and strength of a brush when the unit scale is not one.

Fix curve handle color ID display

Regression in 49f59092e7c8c caused all handles to display using
the 'aligned' theme color.

Arrange flags to fix this, add assert to avoid this happening again.

Also rename flag so it's use is clearer.

deps/windows/embree: Prevent exports leaking out of blender binary

embree marks a few of its functions with a dll_export macro
forcibly exporting these symbols from whatever binary links
them. Given we link embree statically and we do not want these
exports in the blender binary, the macro needs to be a no-op.

Fix T76563: Transforming an auto-aligned point won't set it aligned

Correct previous commit that was checking values not yet initialized,

Cleanup: remove unnecessary header

Introduced in D8007

Added unique name parameter for modifiers as well as MeshTest class

Fixed bug for some binary boolean ops. Fixed a memory leak.

Now the basic binary booleans work from the tool (not the modifier).
Still to do: (1) coplanar and non-connected-component cases;
(2) dissolve triangulation lines and new verts due only to them;
(3) properly transfer mesh attributes from old to new;
(4) hook up to modifier;
(5) attention to and tuning of performance.

Re T77846.

Made binary version of boolean and hooked up to Boolean tool.

Union seems to work. Other ops are flaky because I haven't
quite got the winding number propagation right yet.
