Use `verts` instead of `vertices` and `polys` instead of `polygons`
in the API added in 05952aa94d. This aligns better with
existing naming where the shorter names are much more common.
The only difference between `GPU_SHADER_2D_LINE_DASHED_UNIFORM_COLOR`
and `GPU_SHADER_3D_LINE_DASHED_UNIFORM_COLOR` is that in the vertex
shader the 2D version uses `vec4(pos, 0.0, 1.0)` and the 3D version
uses `vec4(pos, 1.0)`.
But VBOs with 2D attributes work perfectly in shaders that use 3D
attributes. Components not specified are filled with components from
`vec4(0.0, 0.0, 0.0, 1.0)`.
So there is no real benefit to having two different shader versions.

This will simplify porting shaders to python as it will not be
necessary to use a 3D and a 2D version of the shaders.
In python the new name for '2D_UNIFORM_COLOR'' and '3D_UNIFORM_COLOR'
is 'UNIFORM_COLOR', but the old names still work for backward
compatibility.

For copy-on-write, we want to share attribute arrays between meshes
where possible. Mutable pointers like `Mesh.mvert` make that difficult
by making ownership vague. They also make code more complex by adding
redundancy.
The simplest solution is just removing them and retrieving layers from
`CustomData` as needed. Similar changes have already been applied to
curves and point clouds (e9f82d3dc7, 410a6efb74). Removing use of
the pointers generally makes code more obvious and more reusable.
Mesh data is now accessed with a C++ API (`Mesh::edges()` or
`Mesh::edges_for_write()`), and a C API (`BKE_mesh_edges(mesh)`).
The CoW changes this commit makes possible are described in T95845
and T95842, and started in D14139 and D14140. The change also simplifies
the ongoing mesh struct-of-array refactors from T95965.
**RNA/Python Access Performance**
Theoretically, accessing mesh elements with the RNA API may become
slower, since the layer needs to be found on every random access.
However, overhead is already high enough that this doesn't make a
noticible differenc, and performance is actually improved in some
cases. Random access can be up to 10% faster, but other situations
might be a bit slower. Generally using `foreach_get/set` are the best
way to improve performance. See the differential revision for more
discussion about Python performance.
Cycles has been updated to use raw pointers and the internal Blender
mesh types, mostly because there is no sense in having this overhead
when it's already compiled with Blender. In my tests this roughly
halves the Cycles mesh creation time (0.19s to 0.10s for a 1 million
face grid).

With rBe6a557952ead, concerns were reported about missing updates when
the view is moved other than through the Edge Pan system.
Although the transform operator blocks navigation in general, it is
good to avoid these cases.
The view offset, calculated by the Edge Pan system, only affects the
position of the nodes, but forget to update:
- snapping data
- final value of transform
- values used for custom drawing
Therefore, to avoid having to update a lot of scattered data, the
`transformViewUpdate` utility has been implemented to recalculate input
values when the view changes.
This utility does more than is necessary to fix the bug, but with that,
it can work in any situation.

These macros don't compile in C++ because of taking an address of a
temporary and use of designated initializers. Besides that, using
functions can improve debugging and type safety.

SCULPT_undo_push_begin no longer takes an explicit
name. Instead it takes a wmOperator pointer and uses
op->type->name for the name. This is necassary for
the redo panel to work and should fix the entire class
of bugs related to misspelled undo push names.
Cases where the calling operator is not registered
may use SCULPT_undo_push_begin_ex if desired; it
takes a name string as before.
With libepoxy we can choose between EGL and GLX at runtime, as well as
dynamically open EGL and GLX libraries without linking to them.
This will make it possible to build with Wayland, EGL, GLVND support while
still running on systems that only have X11, GLX and libGL. It also paves
the way for headless rendering through EGL.
libepoxy is a new library dependency, and is included in the precompiled
libraries. GLEW is no longer a dependency, and WITH_SYSTEM_GLEW was removed.

and Sergey Sharybin.

Caused by {rB791bfae1d64b}.
The solution was to create the special handle for the Move Clip and Mask
transformation.
One change that cannot be reversed is showing the `G` shortcut in the
statusbar.
But the description of this shortcut was not even correct before.
Add specific modal keyitem for Vert/Edge Slide or TrackBall.
Note that there is a workround to avoid repeated keys in the status bar.

Create a transform conversion type that only considers the Vertex
Custom Data.
This reduces the complexity of converting Meshes and slightly

Rename and refactor several F-curve key manipulation functions, and move
them from `editors` to `blenkernel`.
The functions formerly known as `delete_fcurve_key`,
`delete_fcurve_keys`, and `clear_fcurve_keys` have been moved from
`ED_keyframes_edit.h` to `BKE_fcurve.h` and have been renamed according
to hierarchical naming rules.
Below is a table of the naming changes.
| From | To |
| -- | -- |
| `delete_fcurve_key(fcu, index, do_recalc)` | `BKE_fcurve_delete_key(fcu, index)` |
| `delete_fcurve_keys(fcu)` | `BKE_fcurve_delete_keys_selected(fcu)` |
| `clear_fcurve_keys(fcu)` | `BKE_fcurve_delete_keys_all(fcu)` |
| `calchandles_fcurve()` | `BKE_fcurve_handles_recalc()` |
| `calchandles_fcurve_ex()`| `BKE_fcurve_handles_recalc_ex()` |
The function formerly known as `delete_fcurve_key` no longer takes a
`do_fast` parameter, which determined whether or not to call
`calchandles_fcurve`. Now, the responsibility is on the caller to run
the new `BKE_fcurve_handles_recalc` function if they have want to
recalculate the handles.
In addition, there is now a new static private function called
`fcurve_bezt_free` which sets the key count to zero and frees the key
array. This function is now used in couple of instances of functionally
equivalent code. Note that `BKE_fcurve_delete_keys_all` is just a
wrapper around `fcurve_bezt_free`.
This change was initially spurred by the fact that `delete_fcurve_keys`
was improperly named; this was a good opportunity to fix the location
and naming of a few of these functions.

This commit exposes snap options in transform operators. These options
are needed for Python tools to control snapping without requiring the
tool settings to be adjusted.
The newly exposed options are:
- `snap_elements` for choosing which element(s) of target the source
geometry should snap to (ex: Face Raycast).
- `use_snap_self`, `use_snap_edit`, `use_snap_nonedit`,
`use_snap_selectable_only` for controlling target selection.
- `use_snap_project` for controlling Face Raycast snapping.
- `use_snap_to_same_target` and `snap_face_nearest_steps` for
controlling Face Nearest snapping.

Probably to prevent the radius of a point from being stuck at zero,
the `Shrink/Fatten` curve operator sets a minimum value of `0.001`
for all points being transformed.
This is an inconvenience as these points may have been purposely set
to zero on the panel.
And it also doesn't follow the convention seen in other operators
(which keep the value zero).
So remove this limitation.
Adding Grease Pencil keyframes in the dopesheet (rB92d7f9ac56e0) lead to
