This is often invalid, outdated or misleading

It's more useful to git-blame to find out who has developed the code.

NLA strips support using the keyframe values in a variety of ways:
adding, subtracting, multiplying, linearly mixing with the result
of strips located below in the stack. This is intended for layering
tweaks on top of a base animation.
However, when inserting keyframes into such strips, it simply inserts
the final value of the property, irrespective of these settings. This
in fact makes the feature nearly useless.
To fix this it is necessary to evaluate the NLA stack below the
edited strip and correctly compute the raw key that would produce
the intended final value, according to the mode and influence.

The insert_keyframe function already applies NLA strip to action
time remapping, so doing it in insert_graph_keys/insert_action_keys
is redundant outside the code path that inserts directly into fcurve.
This should be purely an implementation change,
for end users there should be no functional difference.
The entire key configuration is in one file with ~5000 lines of code.
Mostly avoiding code duplication and preserve comments and utility
functions from the C code.
It's a bit long but for searching and editing it's also convenient to
have it all in one file.
Notes:
- Actual keymap is shared by blender / blender_legacy
and stored in `keymap_data/blender_default.py`
This only generates JSON-like data to be passed into
`keyconfig_import_from_data`, allowing other presets to load and
manipulate the default keymap.
- Each preset defines 'keyconfig_data'
which can be shared between presets.
- Some of the utility functions for generating keymap items still
need to be ported over to Python.
- Some keymap items can be made into loops (marked as TODO).

With the new automatic handle algorithm, it is possible to do a lot
of the animation via keyframes without touching the curves. It is
however necessary to change the keyframe interpolation and handle
types in certain cases. Currently the dopesheet/action editor
allows changing the types, but does not show them in any way.
To fix, add a new menu option to display this information. For handle
type, it is represented using the shape of the key icons: diamond for
Free, clipped diamond for Aligned, square for Vector, circle for Auto
Clamp, and cirle with dot for Automatic.
Non-bezier interpolation is a property of intervals between keys,
so it is marked by drawing lines, similar to holds. In this initial
version, only the fact of non-bezier interpolation is displayed,
without distinguishing types. For summaries, the line is drawn at
half alpha if not all curves in the group are non-bezier.
In addition, it is sometimes helpful to know the general direction
of change of the curve, and which keys are extremes. This commit
also adds an option to highlight extremes, based on comparing the
keyed values with adjacent keys. Half-intensity display is used
for overshot bezier extremes, or non-uniform summaries.

Add the necessary colors and/or alpha components to the theme instead.
Also switch the background for ordinary channels to use the likely
intended theme option, instead of the window background color.
The general rule is that the channel color is drawn full strength in the
channel list on the left, and with alpha in the actual key frame area on
the right. This alpha is also reused with bone group colors.

Computation of hold blocks was done by storing ranges (with start and
an end, and likely overlapping) in a tree keyed only by the block start.
This cannot work well, and there even were comments that it is not
reliable in complex cases.
A much better way to deal with it is to split all ranges so they don't
overlap. The most thorough way of doing this is to split at all and every
known keyframe, and in this case the data can actually be stored in the
key column data structures, avoiding the need for a second tree.
In practice, splitting requires a pass to copy this data to newly added
keys, and the necessity to loop over all keyframes in the range being
added. Both are linear and don't add excess algorithmic complexity.
The new implementation also calls BLI_dlrbTree_linkedlist_sync for
its own needs, so the users of the *_to_keylist functions don't have
to do it themselves anymore.

* Proportional pie menu at shift+O.
* Snap pie menu at shift+S.
* Pivot pie menu at comma. Previous comma, ctrl+comma, period
and ctrl+period shortcuts for specific pivot types were removed.

Add tool options to control how select operates (add/sub/set/and/xor).
Note: edit mode armature select still needs to support all options,
this is complicated by how it handles partial end-point selection.
This commit merge the full development done in greasepencil-object branch and include mainly the following features.
- New grease pencil object.
- New drawing engine.
- New grease pencil modes Draw/Sculpt/Edit and Weight Paint.
- New brushes for grease pencil.
- New modifiers for grease pencil.
- New shaders FX.
- New material system (replace old palettes and colors).
- Split of annotations (old grease pencil) and new grease pencil object.
- UI adapted to blender 2.8.

This is the result of nearly two years of development and I want thanks firstly the other members of the grease pencil team: Daniel M. Lara, Matias Mendiola and Joshua Leung for their support, ideas and to keep working in the project all the time, without them this project had been impossible.
Also, I want thanks other Blender developers for their help, advices and to be there always to help me, and specially to Clément Foucault, Dalai Felinto, Pablo Vázquez and Campbell Barton.
This translates the gl calls to the new GPU_ wrappers from D3501.
Given it's tedious and repetitive work, this patch does as much as it can with search + replace, the remainder of the gl calls will need to be manually dealt with on a case by case basis.
This fixes 13 of the 28 failing editors when building without opengl.
