fe5d54d3d0 Gizmo: add new cage2d draw style for circular shapes
`ED_GIZMO_CAGE2D_STYLE_CIRCLE` now draw circles. The previous `ED_GIZMO_CAGE2D_STYLE_CIRCLE`, which drew rectangles, is renamed to `ED_GIZMO_CAGE2D_STYLE_RECTANGLE`. The meaning of `ED_GIZMO_CAGE2D_STYLE_BOX` is now unclear and probably needs to be renamed too.

f17fbf8065 Refactor: Rename Object->obmat to Object->object_to_world
Motivation is to disambiguate on the naming level what the matrix
actually means. It is very easy to understand the meaning backwards,
especially since in Python the name goes the opposite way (it is
called `world_matrix` in the Python API).

It is important to disambiguate the naming without making developers
to look into the comment in the header file (which is also not super
clear either). Additionally, more clear naming facilitates the unit
verification (or, in this case, space validation) when reading an
expression.

This patch calls the matrix `object_to_world` which makes it clear
from the local code what is it exactly going on. This is only done
on DNA level, and a lot of local variables still follow the old
naming.

A DNA rename is setup in a way that there is no change on the file
level, so there should be no regressions at all.

The possibility is to add `_matrix` or `_mat` suffix to the name
to make it explicit that it is a matrix. Although, not sure if it
really helps the readability, or is it something redundant.

baf2835ff7 GPU: remove 'GPU_SHADER_2D_FLAT_COLOR'
The only real difference between `GPU_SHADER_2D_FLAT_COLOR` and
`GPU_SHADER_3D_FLAT_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_FLAT_COLOR'' and '3D_FLAT_COLOR'
is 'FLAT_COLOR', but the old names still work for backward
compatibility.

a296b8f694 GPU: replace GLEW with libepoxy
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.

Includes contributions by Brecht Van Lommel, Ray Molenkamp, Campbell Barton
and Sergey Sharybin.

011327224e Transform Snap: nearest face snap mode, snapping options, refactoring.
This commit adds a new face nearest snapping mode, adds new snapping
options, and (lightly) refactors code around snapping.

The new face nearest snapping mode will snap transformed geometry to the
nearest surface in world space. In contrast, the original face snapping
mode uses projection (raycasting) to snap source to target geometry.
Face snapping therefore only works with what is visible, while nearest
face snapping can snap geometry to occluded parts of the scene. This new
mode is critical for retopology work, where some of the target mesh
might be occluded (ex: sliding an edge loop that wraps around the
backside of target mesh).

The nearest face snapping mode has two options: "Snap to Same Target"
and "Face Nearest Steps". When the Snap to Same Object option is
enabled, the selected source geometry will stay near the target that it
is nearest before editing started, which prevents the source geometry
from snapping to other targets. The Face Nearest Steps divides the
overall transformation for each vertex into n smaller transformations,
then applies those n transformations with surface snapping interlacing
each step. This steps option handles transformations that cross U-shaped
targets better.

The new snapping options allow the artist to better control which target
objects (objects to which the edited geometry is snapped) are considered
when snapping. In particular, the only option for filtering target
objects was a "Project onto Self", which allowed the currently edited
mesh to be considered as a target. Now, the artist can choose any
combination of the following to be considered as a target: the active
object, any edited object that isn't active (see note below), any non-
edited object. Additionally, the artist has another snapping option to
exclude objects that are not selectable as potential targets.

The Snapping Options dropdown has been lightly reorganized to allow for
the additional options.

Included in this patch:

- Snap target selection is more controllable for artist with additional
  snapping options.
- Renamed a few of the snap-related functions to better reflect what
  they actually do now. For example, `applySnapping` implies that this
  handles the snapping, while `applyProject` implies something entirely
  different is done there. However, better names would be
  `applySnappingAsGroup` and `applySnappingIndividual`, respectively,
  where `applySnappingIndividual` previously only does Face snapping.
- Added an initial coordinate parameter to snapping functions so that
  the nearest target before transforming can be determined(for "Snap to
  Same Object"), and so the transformation can be broken into smaller
  steps (for "Face Nearest Steps").
- Separated the BVH Tree getter code from mesh/edit mesh to its own
  function to reduce code duplication.
- Added icon for nearest face snapping.
- The original "Project onto Self" was actually not correct! This option
  should be called "Project onto Active" instead, but that only matters
  when editing multiple meshes at the same time. This patch makes this
  change in the UI.

3772dda4ab Refactor: Snap-related. Clarified attribute names and refactored #defines into enums
The transformation snapping code contains a bunch of `#define`s, some ambiguously or incorrectly named attributes.  This patch contains refactored code to improve this.  This patch does (should) not change functionality of snapping.

Clarified ambiguously / incorrectly named attributes.

  - "Target" is used to refer to the part of the source that is to be snapped (Active, Median, Center, Closest), but several other areas of Blender use the term "target" to refer to the thing being snapped to and "source" to refer to the thing getting snapped.  Moreover, the implications of the previous terms do not match the descriptions.  For example: `SCE_SNAP_TARGET_CENTER` does not snap the grabbed geometry to the center of the target, but instead "Snap transforamtion center onto target".
  - "Select" refers to the condition for an object to be a possible target for snapping.
  - `SCE_SNAP_MODE_FACE` is renamed to `SCE_SNAP_MODE_FACE_RAYCAST` to better describe its affect and to make way for other face snapping methods (ex: nearest).

Refactored related `#define` into `enum`s.  In particular, constants relating to...

  - `ToolSettings.snap_flag` are now in `enum eSnapFlag`
  - `ToolSettings.snap_mode` are now in `enum eSnapMode`
  - `ToolSettings.snap_source` (was `snap_target`) are now in `enum eSnapSourceSelect`
  - `ToolSettings.snap_flag` (`SCE_SNAP_NO_SELF`) and `TransSnap.target_select` are now in `enum eSnapTargetSelect`

As the terms became more consistent and the constants were packed together into meaningful enumerations, some of the attribute names seemed ambiguous.  For example, it is unclear whether `SnapObjectParams.snap_select` referred to the target or the source.  This patch also adds a small amount of clarity.

This patch also swaps out generic types (ex: `char`, `short`, `ushort`) and unclear hard coded numbers (ex: `0`) used with snap-related enumerations with the actual `enum`s and values.

Note: I did leave myself some comments to follow-up with further refactoring.  Specifically, using "target" and "source" consistently will mean the Python API will need to change (ex: `ToolSettings.snap_target` is not `ToolSettings.snap_source`).  If the API is going to change, it would be good to make sure that the used terms are descriptive enough.  For example, `bpy.ops.transform.translate` uses a `snap` argument to determine if snapping should be enabled while transforming.  Perhaps `use_snap` might be an improvement that's more consistent with other conventions.

This patch is (mostly) a subset of D14591, as suggested by @mano-wii.

Task T69342 proposes to separate the `Absolute Grid Snap` option out from `Increment` snapping method into its own method.  Also, there might be reason to create additional snapping methods or options.  (Indeed, D14591 heads in this direction).  This patch can work along with these suggestions, as this patch is trying to clarify the snapping code and to prompt more work in this area.
