The `object_to_world` and `world_to_object` matrices are set during
depsgraph evaluation, calculated from the object's animated location,
rotation, scale, parenting, and constraints. It's confusing and
unnecessary to store them with the original data in DNA.
This commit moves them to `ObjectRuntime` and moves the matrices to
use the C++ `float4x4` type, giving the potential for simplified code
using the C++ abstractions. The matrices are accessible with functions
on `Object` directly since they are used so commonly. Though for write
access, directly using the runtime struct is necessary.
The inverse `world_to_object` matrix is often calculated before it's
used, even though it's calculated as part of depsgraph evaluation.
Long term we might not want to store this in `ObjectRuntime` at all,
and just calculate it on demand. Or at least we should remove the
redundant calculations. That should be done separately though.

The transform system reacts to `CTX_GPENCIL_STROKES` in a special way
that is only useful in `SPACE_VIEW3D`.
There was a similar case fixed in 23e9ebfdbd, but there would be
multiple other places to also check the spacetype.
So now do this more generalized and only ever set `CTX_GPENCIL_STROKES`
if we are in editmode (that check existed before) **and** in
`SPACE_VIEW3D`.

The term `PIL` stands for "platform independent library." It exists since the `Initial Revision`
commit from 2002. Nowadays, we generally just use the `BLI` (blenlib) prefix for such code
and the `PIL` prefix feels more confusing then useful. Therefore, this patch renames the
`PIL` to `BLI`.

Probably caused by ad01cdd7fc.
Once again, problems resetting values due to `td->val` and `td->loc`
sharing the same pointer.
This needs to be avoided, as when resetting it is always expected that
one will be 1D and the other 3D.
Discussed in #114646.
This commit transforms the "alt_navigation" option of the transform
operators into a new modal key item. "PASSTHROUGH_NAVIGATE"
In addition to cleaning up a lot of the code, it allows you to
customize the key chosen to navigate while transforming.
This adds the keybindings, menu, and functionally for the edit mode transform operators to grease pencil v3.
The transform operation include:
* translate, rotate, scale, change opacity, change radius

In the animation transform code, `T_AUTOMERGE` was used
to indicate that the duplicated keys need to be merged.
In perparation of #111051, this no longer makes much sense because
in grease pencil we cannot have two keys in the same channel at the same
frame.
This PR replaces the `T_AUTOMERGE` flag in the animation code to
`T_DUPLICATED_KEYS` to indicate that the transform is being called
with duplicated keyframes.

Using ClangBuildAnalyzer on the whole Blender build, it was pointing
out that BLI_math.h is the heaviest "header hub" (i.e. non tiny file
that is included a lot).
However, there's very little (actually zero) source files in Blender
that need "all the math" (base, colors, vectors, matrices,
quaternions, intersection, interpolation, statistics, solvers and
time). A common use case is source files needing just vectors, or
just vectors & matrices, or just colors etc. Actually, 181 files
were including the whole math thing without needing it at all.
This change removes BLI_math.h completely, and instead in all the
places that need it, includes BLI_math_vector.h or BLI_math_color.h
and so on.
Change from that:
- BLI_math_color.h was included 1399 times -> now 408 (took 114.0sec
to parse -> now 36.3sec)
- BLI_simd.h 1403 -> 418 (109.7sec -> 34.9sec).
Full rebuild of Blender (Apple M1, Xcode, RelWithDebInfo) is not
affected much (342sec -> 334sec). Most of benefit would be when
someone's changing BLI_simd.h or BLI_math_color.h or similar files,
that now there's 3x fewer files result in a recompile.
Pull Request #110944
The `TD_NOTCONNECTED` flag is not set in all cases.
In some cases, such as Meshes, the `FLT_MAX` value better determines
when the `TrasData` is not "connected".
Therefore, this commit removes the `TD_NOTCONNECTED` flag and adapts
the code to rely on the `FLT_MAX` value instead.
These TrasDatas shouldn't even be created in these cases.
Caused by 5ed14e9269.
That commit accidentally removed the `copy_v2_v2_int(t->mval, mval);`
line which was responsible for initializing the value of `mval`.
In the 3D View, after navigating, the initial cursor position was
updated based on the relative position of the cursor in 3D space.
Now the initial relative position is maintained but moved closer to or
further from the 2d center based on zoom.
In order to avoid navigation hotkey conflicts during transform
operations, this commit implements the "Transform Navigation with Alt"
option.
This option is enabled by default and makes navigation hotkeys require
the `Alt` key during a transforming in the 3D View.
