ui_draw_but_COLORBAND
Introduced a new checker shader to be used mostly on transparent areas.
OpenGL immediate mode: interface_draw.c (cont)
ui_draw_but_UNITVEC
Introduced a new shader to be used for simple lighting.
Initial work by Clément Foucault with contributions from Dalai Felinto
(mainly per-collection engine settings logic, and depsgraph iterator placeholder).
This makes Blender require OpenGL 3.3. Which means Intel graphic card
and OSX will break. Disable CLAY_ENGINE in CMake in those cases.
This is a prototype render engine intended to help the design of real
render engines. This is mainly an engine with enphasis in matcap and
ambient occlusion.
Implemented Features
--------------------
* Clay Render Engine, following the new API, to be used as reference for
future engines
* A more complete Matcap customization with more options
* Per-Collection render engine settings
* New Ground Truth AO - not enabled
Missing Features
----------------
* Finish object edit mode
- Fix shaders to use new matrix
- Fix artifacts when edge does off screen
- Fix depth issue
- Selection sillhouette
- Mesh wires
- Use mesh normals (for higher quality matcap)
- Non-Mesh objects drawing
- Widget drawing
- Performance issues
* Finish mesh edit mode
- Derived-Mesh-less edit mode API (mesh_rende.c)
* General edit mode
- Per-collection edit mode settings
* General engines
- Per-collection engine settings
(they are their, but they still need to be flushed by depsgraph, and
used by the drawing code)

User Commit Log
---------------
* New Layer and Collection system to replace render layers and viewport layers.
* A layer is a set of collections of objects (and their drawing options) required for specific tasks.
* A collection is a set of objects, equivalent of the old layers in Blender. A collection can be shared across multiple layers.
* All Scenes have a master collection that all other collections are children of.
* New collection "context" tab (in Properties Editor)
* New temporary viewport "collections" panel to control per-collection
visibility
Missing User Features
---------------------
* Collection "Filter"
Option to add objects based on their names
* Collection Manager operators
The existing buttons are placeholders
* Collection Manager drawing
The editor main region is empty
* Collection Override
* Per-Collection engine settings
This will come as a separate commit, as part of the clay-engine branch
Dev Commit Log
--------------
* New DNA file (DNA_layer_types.h) with the new structs
We are replacing Base by a new extended Base while keeping it backward
compatible with some legacy settings (i.e., lay, flag_legacy).
Renamed all Base to BaseLegacy to make it clear the areas of code that
still need to be converted
Note: manual changes were required on - deg_builder_nodes.h, rna_object.c, KX_Light.cpp
* Unittesting for main syncronization requirements
- read, write, add/copy/remove objects, copy scene, collection
link/unlinking, context)
* New Editor: Collection Manager
Based on patch by Julian Eisel
This is extracted from the layer-manager branch. With the following changes:
- Renamed references of layer manager to collections manager
- I doesn't include the editors/space_collections/ draw and util files
- The drawing code itself will be implemented separately by Julian
* Base / Object:
A little note about them. Original Blender code would try to keep them
in sync through the code, juggling flags back and forth. This will now
be handled by Depsgraph, keeping Object and Bases more separated
throughout the non-rendering code.
Scene.base is being cleared in doversion, and the old viewport drawing
code was poorly converted to use the new bases while the new viewport
code doesn't get merged and replace the old one.
Python API Changes
------------------
```
- scene.layers
+ # no longer exists
- scene.objects
+ scene.scene_layers.active.objects
- scene.objects.active
+ scene.render_layers.active.objects.active
- bpy.context.scene.objects.link()
+ bpy.context.scene_collection.objects.link()
- bpy_extras.object_utils.object_data_add(context, obdata, operator=None, use_active_layer=True, name=None)
+ bpy_extras.object_utils.object_data_add(context, obdata, operator=None, name=None)
- bpy.context.object.select
+ bpy.context.object.select = True
+ bpy.context.object.select = False
+ bpy.context.object.select_get()
+ bpy.context.object.select_set(action='SELECT')
+ bpy.context.object.select_set(action='DESELECT')
-AddObjectHelper.layers
+ # no longer exists
```
Marks matrix state as dirty so shader will use the latest values from glScale, glTranslate, etc.
We'll remove this after transitioning 100% to the new matrix API, which handles this sort of thing automatically.
Part of T49450
-Remove NPOT check as it should be supported by default with OGL 3.3
-All custom texture creation follow the same path now
-Now explicit texture format is required when creating a custom texture (Non RGBA8)
-Support for arrays of textures

This code was already disabled.
We might be able to simplify GPU_check_scaled_image even further. Maybe even delete it? Just removing the obvious stuff now.
Keeping is_power_of_2_resolution function since it is still used in DXT logic.
This includes a few fixes in the MBC_ api.
The idea here is for this to be the only interface the render engines
will deal with for the meshes.
If we need to expose special options for sculpting engine we refactor
this accordingly. But for now we are shaping this in a per-case base.
Note:
* We still need to hook up to the depsgraph to force clear/update of
batch_cache when mesh changes
(I'm waiting for Sergey Sharybin's depsgraph update for this though)
* Also ideally we could/should use BMesh directly instead of
DerivedMesh, but this will do for now.
Note 2:
In the end I renamed the `BKE_mesh_render` functions to `static
mesh_render`. We can re-expose them as BKE_* later once we need it.

Had to add a few utility functions to replace existing functions. Let me know if these are duplicates.

This does not address stapling shader in 2.8, though the solution can be
similar (own shader, not polutting interlace shader).

This reverts commit 5aa19be912 and b4a721af69.
Due to postponement of particle system rewrite it was decided to put particle code
back into the 2.8 branch for the time being.
Needed because deps graph can destroy objects from any thread. We ran into the same problem & solved it in GPU_buffers.
Implemented in C++11 since it provides the needed machinery. The interface is in C like the rest of Gawain.
This will make triple buffer used by default for such configuration.
Ideally we would switch to triple buffer on all platforms, but let's
do it in 2.8 branch and don't open can of worms in master now.
This should solve issues like T49945.
Just as mentioned in title. Need new functions for calls found in `transform.c`

Most useful for packed normals, which take 1/3 the space of float32 normals.
2-bit alpha|w component is ignored for now.
Batch API can use these now, will add support to immediate mode API if desired.
Enabling on Windows first. Will enable on all platforms after we switch Blender to core profile.
Drop SciTech support & workarounds for WinCE and OpenGL ES.
AMD_debug_output is still in the code but disabled. Once I verify the newer extensions are available on all the GPU + OS combos we support we can delete this disabled code.
Motivations:
1) GLenum is too broad; tightly-defined enum just for this is safer.
2) enable a Vulkan future
New code should use these instead of GL_FLOAT etc. When all existing code has been updated to use new enum, we can drop compatibility with GLenum values.
Early work towards 10_10_10 format, more to come soon.
As our library of built-in shaders grows, it's important to create, access, and discard them efficiently.
Lookup via GPU_shader_get_builtin is now constant time instead of linear (# of built-in shaders). This is called very often with our new immediate mode.
Creation and discard are unified.
Adding a new shader requires fewer steps.
365 lines shorter :D

This is the radial control that appears when we change the size of a brush in sculpt and vertex and texture painting modes, by pressing "f".
Also includes a new built-in shader that can be useful in other places.

Gawain does very strict runtime checking to help us catch coding errors. Final release should disable most of these checks, so I'm disabling now for all non-debug builds.
When writing Blender code that uses Gawain, always make debug builds and test there! "make lite debug" is my favorite.
