This was due to a double offset of the wireframe. We also reduce
the wireframe offset. The look of the wireframe overlay changes
a little with on distant wires.
This cleans up a bit of duplicated code and some confusion about
what was culled and what wasn't.
Now everything is culled based on the given object pointer.
If the object pointer is NULL there is no culling performed.
When XRay is turned on the mesh analysis did not draw correct. This
change won't draw the mesh analysis overlay when xray is turned on.
In terms of giving the user a visual feedback of this limitation we
render the overlay options inactive.

- Make edges darker in vert & face select mode (making more
contrast to not loose the topology). Downside is less select
edges visibility in vertex mode. But I'm confident that it's not
as painfull as it seems.
- Make select faces less saturated to have more color contrast
between select faces and edges.
- Make unselected faces white to increase contrast with faces and
edges. The brightening is negligeable for bright surfaces and
help readability on darker surfaces. Reminder that if the faces
overlays are too distracting (i.e: uv mapping, or texturing) they
can be toggled off in the overlay panel.

This will have multiple benefit.
TODO detail benefits (culling, more explicit, handling of clipping planes)
For now the view usage is wrapped to make changes needed more progressive.
Enabling the drawing of the mesh analysis overlay.
Currently the settings are part of the scene toolsettings. What makes sense,
for 3d printing, but does not fit well with the per viewport blender 2.80
overlays.

This removes the large edges and instead use colors to hint in which
selection mode the user is.
The component in each individual selection mode is more prominent to add
more emphasis. The other components are less prominent and dimmed.
A minor default theme changes needed to be made to keep clarity in all
combinations.
Forcing old behavior (no selection mode hit) could be done quite easily
by just making the 2 booleans true (selectFaces and selectEdges).

Edit mode shows the mesh elements in X-ray mode even if alpha is set to
1. Now the code takes this into account so that you can still select
visible mesh elements in X-ray edit mode.
view3d_draw_legacy need to be updated with the new XRAY flag macros to
avoid crashes. Additional cleanup of the XRAY macro flags were done.
Now the depth order of objects when trying to select them is only used when not in X-ray mode.
Before, this was only the case in wireframe mode regardless of X-ray settings.
I've also unified the usage of V3D_XRAY and XRAY_FLAG as they were basically copies of each other.

Instead of doing some fancy stencil buffer tricks, just clear the depth
buffer before the "in front" meshes.
Fix T58841 Hidden Wire when in Edit Mode disables In Front Option
Enable depth picking by default.
This adds new 'gpu_flag' since it's not so relevant to add GPU drawing
options into uiflag & uiflag2.
This resets the recently added smooth edge flag.
Requested by some users who prefer old wireframe precision.
Smooth wires are still enabled by defaults as they don't have a noticeable
perf impact.
Application restart is needed for changes to take effects.
This avoid edges covering a part of vertices.
This comes at a (very minor) perf cost as vertices can cover some edges
pixels and early discard them with the depth test. But this only happens
in artificialy dense mesh and is not a real problem for common cases.
This make sure only one line is drawn per edge.
It makes the function mesh_create_edit_loops_points_lines() non-thread safe
but this is fine as of now because nothing is multithreaded at this point.
Also this is the only function use this flag so it might be OK.
The side effect is that we don't need to use depth test in edit mode
overlay so the masking artifact will not appear.
This make it (theoriticaly) compatible with all supported hardware with
consistent results.
Also we now draw the lines with analytic anti-aliasing instead of relying
on MSAA (which offers less benefits in our case).
The remaining aliasing comes from edges cut in half by the mesh which is
not rendered with MSAA. Hopefully this is not too much distracting and only
happen if the face is almost parallel to the view.
Needed to fix T61196, supporting clipped back-buffer in the 3D view
which is done outside the draw module.
It was also inconvenient having DRW_shader_* versions of GPU_shader_*
API calls.
- Clipping distances are now supported as a shader configuration
for builtin shaders.
- Add shader config argument when accessing builtin shaders.
- Move GPU_shader_create_from_arrays() from DRW to GPU.
This adds a new geometry shader (specific to edit mesh for now) that
reproduces the effect of glLineWidth > 1.0, since this is not supported on
all platform.
This fix could be generalized to other shaders later.
- Add manual depth offset to vertices and edges.
- Revert to plain edge decoration.
- Fix active edge coloring.
- Remove active face display if not in face selection mode.
- Add wide line support.
This is work in progress. Look is not final.
This align data VBO data structure used for edti cage drawing to the one
use for normal drawing.
We no longer use barycentric coords to draw the lines an just rasterize
line primitives for edge drawing. This is a bit slower than using the
previous fast method but faster than the "correct" (edge artifact free)
method. This also make the code way simpler.
This also makes it possible to reuse possible and normal vbos used for
shading if the edit cage matches the
This also touches the UV batch code to share as much render data as
possible. The code also prepare for edit cage "modified" drawing cage (with
modifier applied) but is not enabled since selection and operators does not
work with modified cage yet.
BF-admins agree to remove header information that isn't useful,
to reduce noise.
