There are now 3 categories in the overlay popover:
- Navigation
- Active (camera, lamp... etc)
- Tool (manipulator)
The user preference for mini axis now controls if the mini axis
displays minimal or a full-interactive widget.
Part of design: T55863
- Change gl_context_mutex to a ticket mutex ensuring interactivity even
when rendering.
- Add DRW_custom_pipeline for using DRW outside of the viewport and render
pipeline.
- DRW_opengl_render_context_*** and DRW_gawain_render_context_*** to use
with DRW_custom_pipeline.
- Add possibility to bypass deferred compilation on demand (not User
demand).
- Add union to access DRWMatrixState members more easily.
Trying to have a single option for this is too likely to be
insufficient in some cases.
Instead, support object type visibility & selectability per view-port.
This is because depth test is set before drawing anything now. There is no
case where we want to draw without depth test that is not selection and
this case is not handle by v3d->zbuf anymore.
UI assume depth test is off by default. The DRWManager assume it's on.
This should fix T55623.
This puts the wireframe on top of the weight in weight paint mode,
sculpt mode ...
Wireframe should be colored differently if the object is in paint mode
but it's not there yet.
There was a Full Shading bool that was shared across the WP, VP and TP
modes. This commit makes some changes:
- Replace the bool with a factor. This gives the user more control on
the visibility.
- Also draw it on top of the Material and Rendered mode so the user can
control what he needs. In certain cases you don't want to see the final
rendered material, but the actual texture.
- Removed the skipping of objects when in paint modes. As now the paint
modes are blended.
the use of the texture drawtype is limited. so who should we have it
this prominent on the screen. By adding it as a shading.color_type
option we should save some screenspace.
Currently with a debug build there is a race condition where the mutex is released before the DST structure is reset to 0xFF, meaning when multiple threads are using the DRWManager it can get cleared when the main thread is using it, causing crashes.

The ClayEngine was introduced to test the blender2.8 architecture during
development. As currently we have the wanted features implemented with
matcaps we are going to remove the clay engine as it was never intended
to be an official releasable engine
Note: The test cases are never run. But when enabled will be skipped as
they were implemented over the Clay Engine
This way they can be init in their owner thread. Contexts should not be
shared accross threads. Once you make a context active on a thread it is
owned by the thread.
This commit only have the GLX backend updated but should not break orther
platform.
Manipulators which aren't explicitly activated via tools are now hidden.
Tool manipulators are kept because it doesn't make sense to interact
with a tool with hidden manipulators.
This commit restores support for Motion Path drawing in 2.8 (as it wasn't ported over
to the new draw engines earlier, and the existing space_view3d/drawanimviz.c code was
removed during the Blender Internal removal).
Notes:
* Motion Paths are now implemented as an overlay (enabled by default).
Therefore, you can turn all of them on/off from the "Overlays" popover
* By and large, we have kept the same draw style as was used in 2.7
Further changes can happen later following further design work.
* One change from 2.7 is that thicker lines are used by default (2px vs 1px)
Todo's:
* There are some bad-level calls introduced here (i.e. the actgroup_to_keylist() stuff).
These were introduced to optimise drawing performance (by avoiding full keyframes -> keylist
conversion step on each drawcall). Instead, this has been moved to the calculation step
(in blenkernel). Soon, there will be some cleanups/improvements with those functions,
so until then, we'll keep the bad level calls.

This mean you can store data used for drawing inside the object engine
data.
Also fixes T55243 Crash in ASAN debug builds due to use-after-free memory in draw code - instances issue?
This new system use transform feedback to compute subdivided hair points
position. For now no smoothing is done between input points.
This new system decouple the strands data (uv, mcol) with the points
position, requiring less update work if only simulation is running.
In the future, we can have compute shader do the work of the feedback
transform pass since it's really what it's meant to. Also we could generate
the child particles during this pass, releasing some CPU time.
draw_hair.c has been created to handle all of the Shading group creations
as well as subdivision shaders.
We store one final batch per settings combination because multiple viewport
or render could use the same particle system with a different subdivision
count or hair shape type.
This new API aim to provide simple function that can be called by the draw
engines during any phase of the draw pipeline. All calls are saved and
issued after all engines have finished rendering.
This removes the need of setuping special passes and shading groups for some
simple debug drawing.
