A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.
This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.
Note that this does not make it so the Blender Foundation is
the only holder of the copyright in those files, and developers
who do not have a signed contract with the foundation still
hold the copyright as well.
Another aspect of this change is using SPDX format for the
header. We already used it for the license specification,
and now we state it for the copyright as well, following the
FAQ:
https://reuse.software/faq/
Use a shorter/simpler license convention, stops the header taking so
much space.
Follow the SPDX license specification: https://spdx.org/licenses
- C/C++/objc/objc++
- Python
- Shell Scripts
- CMake, GNUmakefile
While most of the source tree has been included
- `./extern/` was left out.
- `./intern/cycles` & `./intern/atomic` are also excluded because they
use different header conventions.
doc/license/SPDX-license-identifiers.txt has been added to list SPDX all
used identifiers.

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`.

Surrounding includes with an 'extern "C"' block is not necessary anymore.
Also that made it harder to add any C++ code to some headers, or include headers
that have "optional" C++ code like `MEM_guardedalloc.h`.
I tested compilation on linux and windows (and got help from @LazyDodo).
If this still breaks compilation due to some linker error, the header containing
the symbol in question is probably missing an 'extern "C"' block.

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This is often invalid, outdated or misleading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.

From the patch comment:
It allows Blender to load:
- 1, 8, 10, 12 and 16 bits files. For 10 and 12 bits files, packed or
filled type A/B are supported.
- RGB, Log, Luma and YCbCr colorspaces.
- Big and little endian storage.
- Multi-elements (planar) storage.
It allows Blender to save :
- 8, 10, 12 and 16 bits file. For 10 and 12 bits files, the most used
type A padding is used.
- RGB and Log colorspaces (Cineon can only be saved in Log colorspace).
For Log colorspace, the common default values are used for gamma,
reference black and reference white (respectively 1.7, 95 and 685 for
10 bits files).
- Saved DPX/Cineon files now match the viewer.
Some files won't load (mostly because I haven't seen any of them):
- Compressed files
- 32 and 64 bits files
- Image orientation information are not taken in account. Here too,
I haven't seen any file that was not top-bottom/left-right oriented.
standard for film scanning, 10 bits/channel and logarithmic. DPX is
derived from Cineon as the ANSI/SMPTE industry standard.
DPX supports 16 bits color/channel, linear as well as logarithmic.
Code has been gratefully copied from CinePaint and was integrated in
Blender by Joe Eagar.
According to CinePaint's dev Robin Rowe the DPX code defaults to log
colorspace. Can't find in the code clues yet how to enable/disable that.
However, tests with write/read of DPX seems to show no visible loss by
log conversion code. Might be because it uses the entire 16 bit range...
CinePaint dpx files have been succesfully imported in a Quantel IQ HD/2K
finishing/grading set without problem, so for now I guess we can
use it! :)
Changes in code: added tests for image magic numbers before entering
the actual reading code. Prevents error prints, and makes it faster too.
(Note; this because Blender doesn't check for extensions, but calls
reading functions on every file until one accepts it. :)
