This is unreported. When using volume opacity 0.0, the wires were not visible
(nor were they in other cases, but this was the most obvious one).
The volume itself is still glitchy, and slightly worse than 2.79. I
still don't know how to fix this though. It seems a common problem
(see T62262).
This makes the bones transparent when the object or the viewport display
type is Wireframe. This is in order to make things consistent.
In object mode all bones are fully transparent to not create more visual
noise if the scene is complex.
Another small addition is that the Bounding Box draw mode now works as
expected on armatures.
The option is separated from the solid mode color option.
Random color uses the same method as solid mode.
Selection state is indicated by a brighter color that is outside the
brightness range of the unselected state colors. The active state is
indicated by the outlines that is, now, still drawn in wireframe mode.
Coloring of the selection / active outline is not optimal because it
can look ugly in some cases of color combination. But the outline color
is using index range coloring so it's not trivial to change the color of
the outline per object. For now we use the same outline color used in solid
mode for consistency and also still add an emphasis on the selected objects.
The Single color option uses the theme color. Maybe it would be nice to
change the name of it in a latter commit to avoid confusion.
If all axis and grid options were turned off, the grid in the main ortho views would not be rendered.
Now we force rendering of the grid regardless of the settings when in one of the main ortho views.

The dependency graph now handles updating image users to point to the current
frame, and tags images to be refreshed on the GPU. The image editor user is
still updated outside of the dependency graph.
We still do not support multiple image users using a different current frame
in the same image, same as 2.7. This may require adding a GPU image texture
cache to keep memory usage under control. Things like rendering an animation
while the viewport stays fixed at the current frame works though.
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 was deliberately disabled since I didn't get the drawing working
originally. It is fully working now.
Note: camera lens widget still needs to be fixed since it still draws it
wrongly.
BF-admins agree to remove header information that isn't useful,
to reduce noise.

This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
Originally I wanted to avoid adding draw manager specific ifdef's all
over generic shaders however this isn't needed in so many places.
Also there are shaders that are only used by the draw manager so
duplicating them only to have the original unused doesn't make sense.
DRW_shader_get_builtin_shader can replace GPU_shader_get_builtin_shader
when we need to support clipping.
Use this for loose point & wire drawing in object mode,
clips edges in lattice edit mode.
Add 'G_draw' for all draw manager globals,
avoids adding extern to each file.
Connection between `ts` and `globals_ubo` wasn't obvious,
now called `G_draw.block` & `G_draw.block_ubo`.
Instead of doing manual ray-plane intersection we use normalized positions
of the grid mesh and apply scaling after interpolation so that we keep
good precision even at really far distances.
Precision is now two order of magnitude better and does not produce the
same kind of artifact at lower clip start values.
This commit also cleanup the implementation.
