This replaces header include guards with `#pragma once`.
A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`),
because they are used in other places.
This patch has been generated by P1561 followed by `make format`.

This removes extern-C blocks around other includes and adds
such blocks for some headers that need them.

While \file doesn't need an argument, it can't have another doxy
command after it.

Move \ingroup onto same line to be more compact and
make it clear the file is in the group.

BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading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.

Brecht authored this commit, but he gave me the honours to actually
do it. Here it goes; Blender Internal. Bye bye, you did great!
* Point density, voxel data, ocean, environment map textures were removed,
as these only worked within BI rendering. Note that the ocean modifier
and the Cycles point density shader node continue to work.
* Dynamic paint using material shading was removed, as this only worked
with BI. If we ever wanted to support this again probably it should go
through the baking API.
* GPU shader export through the Python API was removed. This only worked
for the old BI GLSL shaders, which no longer exists. Doing something
similar for Eevee would be significantly more complicated because it
uses a lot of multiplass rendering and logic outside the shader, it's
probably impractical.
* Collada material import / export code is mostly gone, as it only worked
for BI materials. We need to add Cycles / Eevee material support at some
point.
* The mesh noise operator was removed since it only worked with BI
material texture slots. A displacement modifier can be used instead.
* The delete texture paint slot operator was removed since it only worked
for BI material texture slots. Could be added back with node support.
* Not all legacy viewport features are supported in the new viewport, but
their code was removed. If we need to bring anything back we can look at
older git revisions.
* There is some legacy viewport code that I could not remove yet, and some
that I probably missed.
* Shader node execution code was left mostly intact, even though it is not
used anywhere now. We may eventually use this to replace the texture
nodes with Cycles / Eevee shader nodes.
* The Cycles Bake panel now includes settings for baking multires normal
and displacement maps. The underlying code needs to be merged properly,
and we plan to add back support for multires AO baking and add support
to Cycles baking for features like vertex color, displacement, and other
missing baking features.
* This commit removes DNA and the Python API for BI material, lamp, world
and scene settings. This breaks a lot of addons.
* There is more DNA that can be removed or renamed, where Cycles or Eevee
are reusing some old BI properties but the names are not really correct
anymore.
* Texture slots for materials, lamps and world were removed. They remain
for brushes, particles and freestyle linestyles.
* 'BLENDER_RENDER' remains in the COMPAT_ENGINES of UI panels. Cycles and
other renderers use this to find all panels to show, minus a few panels
that they have their own replacement for.

This patch moves all the functionality previously in SceneRenderLayer to SceneLayer.
If we want to rename some of these structs now would be a good time to do it, before they are in SceneLayer.
Everything should be working, though I will test things further tomorrow. Once this is committed depsgraph can get
rid of the workaround added in rna_Main_meshes_new_from_object and finish whatever this patch was preventing from being finished.
This patch also adds a few placeholders for the overrides (samples, ...). These are obviously not working, so some unittests that rely on 'lay', and 'zmask' will fail.
This patch does not addressed the change of moving samples to ViewRender (I have this as a separate patch and needs some separate discussion).
Following next is the individual note of the individual parts that were committed.
Note 1: It is up to Cycles to still get rid of exclude_layer internally.
Note 2: Cycles still need to handle its own doversion for the use_layer_samples cases and
(1) Remove the override as it is
(2) Add a new override (scene.cycles.samples) if scene.cycles.use_layer_samples != IGNORE
Respecting the expected behaviour when scene.cycles.use_layer_samples == BOUNDED.
Note 3: Cycles still need to implement the per-object holdout
(similar to how we do shadow catcher).
Note 4: There are parts of the old (Blender Internal) rendering pipeline that is still
using lay, e.g., in shi->lay.
Honestly it will be easier to purge the entire Blender Internal code away instead of taking things from it bit by bit.

Engine is not stored in WorkSpaces. That defines the "context" engine, which
is used for the entire UI.
The engine used for the poll of nodes (add node menu, new nodes when "Use Nodes")
is obtained from context.
Introduce a ViewRender struct for viewport settings that are defined for
workspaces and scene. This struct will be populated with the hand-picked
settings that can be defined per workspace as per the 2.8 design.
* use_scene_settings
* properties editor: workshop + organize context path
Use Scene Settings
==================
For viewport drawing, Workspaces have an option to use the Scene render
settings (F12) instead of the viewport settings.
This way users can quickly preview the final render settings, engine and
View Layer. This will affect all the editors in that workspace, and it will be
clearly indicated in the top-bar.
Properties Editor: Add Workspace and organize context path
==========================================================
We now have the properties of:
Scene, Scene > Layer, Scene > World, Workspace
[Scene | Workspace] > Render Layer > Object
[Scene | Workspace] > Render Layer > Object > Data
(...)

without the underscores these clogged up the namespace for autocompleation which was annoying.

The old implementation was added quite hackish (talking about 10 yr ago).
You also had to make a small image slice, which was extended Xparts in
size. That also required to adjust the camera angle. Very clumsy.
Now; when enabling the Panorama option, it will automatically apply the
panorama effect on the vertically aligned tiles. You can just enable or
disable the "Pano" button, to get a subtle lens effect like this:
(without pano)
http://www.blender.org/bf/rt.jpg
(with pano)
http://www.blender.org/bf/rt1.jpg
For Panorama render, the minimum slice size has been hardcoded to be 8
pixels. The XParts button goes up to 512 to allow that. In practice,
rendering 64 slices will already give very good images for a wide angle
lens of 90 degrees, the curvature of straight lines then is equal to
a circle of 256 points.
Rendering a full 360 degree panorama you do by creating an extreme wide
angle camera. The theory says camera-lens 5 should do 360 degrees, but
for some reason my tests reveil it's 5.1... there's a rounding error
somewhere, maybe related to the clipping plane start? Will look at that
later. :)
Also note that for each Xpart slice, the entire database needs to be
rotated around camera to correct for panorama, on huge scenes that might
give some overhead.
Threaded render goes fine for Panorama too, but it can only render the
vertically aligned parts in parallel. For the next panorama slice it has
to wait for all threads of the current slice to be ready.
On reading old files, I convert the settings to match as closely as
possible the new situation.
Since I cannot bump up the version #, the code detects for old panorama
by checking for the image size. If image width is smaller than height, it
assumes it's an old file (only if Panoroma option was set).

- Button option "Single" in render-layer panel will enable to only render
the currently indicated render-layer. It will also skip compositing.
- Brought back the 'Local View' render. This will only render the visible
objects, but with lights from the original view-layers.
To make the option useful, it also temporal enables 'Single', which has
the a disadvantage that you need to set the correct render-layer.
It is a bit a tricky option though... since its quite invisble and
confusing for people who don't know the feature. This might become either
a button in 3d header, or use a popup requester to confirm, or... will
need to think over!
At least; both options display in render window a text to denote the option.

I noticed still several cases where the Imbuf library was called within a
thread... and that whilst the Imbuf itself isn't threadsafe. Also the
thread lock I added in rendering for loading images actually didn't
work, because then it was still possible both threads were accessing the
MEM_malloc function at same time.
This commit nearly fully replaces ImBuf calls in compositor (giving another
nice speedup btw, the way preview images in Nodes were calculated used
clumsy imbuf scaling code).
I've also centralized the 'mutex' locking for threading, which now only
resides in BLI_threads.h. This is used to secure the last ImBuf calls
I cannot replace, which is loading images and creating mipmaps.
Really hope we get something more stable now!

- ZTransp render now also delivers Z values and Speed vectors in passes
Note that speed vectors accumulate within a pixel to store the minimum,
so rendering ztransp on top of a non-moving plane won't give speed...
Best results you get is by rendering it in a separate layer.
The Z value stored is the closest visible transparent face in the pixel.
Fixes:
- Render to 'spare page' has been enabled again. Because of the strict
separation of Render and UI, but especially because a 'render result' now
can consist of unlimited images, I've not made this a Render feature.
Instead, the render-window itself stores the 'spare' image... I also
had to change the convention for it a bit.
Now, instead of having two "render buffers" (which was a render feature),
the RenderWindow will store each previous frame on a re-render. This
storing will only start after you've pressed 'Jkey' once, but then always
will happen for as long the rendered image is same size as previously.
For clarity, I've also renamed the window title, to 'previous frame'.
- RenderWindow shows alpha again on Akey
- Display of the Zvalues in ImageWindow has been tweaked. White now denotes
closest, and the color range goes from camera clip-sta to clip-end.
- Bugfix: on splitting/merging/duplicating windows, the 3D Previewrender was
not always freed correctly, potentially causing crashes or memory leaks.

A full detailed description of this will be done later... is several days
of work. Here's a summary:
Render:
- Full cleanup of render code, removing *all* globals and bad level calls
all over blender. Render module is now not called abusive anymore
- API-fied calls to rendering
- Full recode of internal render pipeline. Is now rendering tiles by
default, prepared for much smarter 'bucket' render later.
- Each thread now can render a full part
- Renders were tested with 4 threads, goes fine, apart from some lookup
tables in softshadow and AO still
- Rendering is prepared to do multiple layers and passes
- No single 32 bits trick in render code anymore, all 100% floats now.
Writing images/movies
- moved writing images to blender kernel (bye bye 'schrijfplaatje'!)
- made a new Movie handle system, also in kernel. This will enable much
easier use of movies in Blender
PreviewRender:
- Using new render API, previewrender (in buttons) now uses regular render
code to generate images.
- new datafile 'preview.blend.c' has the preview scenes in it
- previews get rendered in exact displayed size (1 pixel = 1 pixel)
3D Preview render
- new; press Pkey in 3d window, for a panel that continuously renders
(pkey is for games, i know... but we dont do that in orange now!)
- this render works nearly identical to buttons-preview render, so it stops
rendering on any event (mouse, keyboard, etc)
- on moving/scaling the panel, the render code doesn't recreate all geometry
- same for shifting/panning view
- all other operations (now) regenerate the full render database still.
- this is WIP... but big fun, especially for simple scenes!
Compositor
- Using same node system as now in use for shaders, you can composit images
- works pretty straightforward... needs much more options/tools and integration
with rendering still
- is not threaded yet, nor is so smart to only recalculate changes... will be
done soon!
- the "Render Result" node will get all layers/passes as output sockets
- The "Output" node renders to a builtin image, which you can view in the Image
window. (yes, output nodes to render-result, and to files, is on the list!)
The Bad News
- "Unified Render" is removed. It might come back in some stage, but this
system should be built from scratch. I can't really understand this code...
I expect it is not much needed, especially with advanced layer/passes
control
- Panorama render, Field render, Motion blur, is not coded yet... (I had to
recode every single feature in render, so...!)
- Lens Flare is also not back... needs total revision, might become composit
effect though (using zbuffer for visibility)
- Part render is gone! (well, thats obvious, its default now).
- The render window is only restored with limited functionality... I am going
to check first the option to render to a Image window, so Blender can become
a true single-window application. :)
For example, the 'Spare render buffer' (jkey) doesnt work.
- Render with border, now default creates a smaller image
- No zbuffers are written yet... on the todo!
- Scons files and MSVC will need work to get compiling again
OK... thats what I can quickly recall. Now go compiling!
