For Blender builtin configurations the option to choose the select mouse remains
and is now also in the splash screen. It works by changing the keymap dynamically
in the script, rather than using special events.
The system of automatic switching of events was not flexible enough to deal with
side effects that require further keymap changes, so it is now under more manual
control in the script.
This breaks compatibility for some scripts and exported key configurations.
These can be fixed by replacing SELECTMOUSE, ACTIONMOUSE, EVT_TWEAK_S and
EVT_TWEAK_A with appropriate LEFTMOUSE, RIGHTMOUSE, EVT_TWEAK_L and
EVT_TWEAK_R events.
Other than that, there should be no functional changes.
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).

This was broken since cca87ccc75
The problem was that as this popover was defined in the C-code
for the Graph Editor, the relevant panel never got added to the
WM_paneltype registry, since only Python defined panels get
WM_paneltype_add() called when they are defined.
Since the majority of panels defined for regions are only used there,
a more localised fix was applied here by only adding the driver popover
to the global list manually.
* 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.

Recently @sergey found that hard-coding evaluation of certain very
common driver expressions without calling the Python interpreter
produces a 30-40% performance improvement. Since hard-coding is
obviously not suitable for production, I implemented a proper
parser and interpreter for simple arithmetic expressions in C.
The evaluator supports +, -, *, /, (), ==, !=, <, <=, >, >=,
and, or, not, ternary if; driver variables, frame, pi, True, False,
and a subset of standard math functions that seem most useful.
Booleans are represented as numbers, since within the supported
operation set it seems to be impossible to distinguish True/False
from 1.0/0.0. Boolean operations properly implement lazy evaluation
with jumps, and comparisons support chaining like 'a < b < c...'.
Expressions are parsed into a very simple stack machine program
that can then be safely evaluated in multiple threads.

Rebuilding depsgraph is not enough, with COW we also need to ensure COW
copies get updated accordingly.
Had to tweak the generic update system here, since it was always passed
a NULL pointer for the callback arg, this should not change existing
behavior (besides crash fixing ;) )...
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.
The previous commit only solves the problem when using the default
theme using factory settings. For previously saved themes, there could
still be problems, as the alpha values were still 0.
This commit improves the logic here so that while keyframe points on
unselected F-Curves will still get faded out (to not stick out too much
from the curves they live on), but the effect will not be as pronounced
(i.e. the points will stay visible all the time).
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.

This shouldn't really be part of the windowmanager code. Pulling it out
now, so that we can reuse in RNA when switching display modes,
(and perhaps other places later)
Limit to a restricted set of built-ins, as well as the math module.
Also restrict of op-codes, disallowing imports and attribute access.
This allows most math expressions to run
without any performance cost once the initial check is done.
See: D1862 for details.
The copy/paste driver variables buttons currently only work when used in the
Graph Editor as they rely on being able to have the "active F-Curve" context
info that's only present in the Graph Editor (in Drivers Editor mode).
Instead of having them constantly greyed out in the popover, it's easier
to just hide them for now. Besides, this is probably more of an "advanced"
feature that we don't need to expose in the simple UI.
This fixes the problem where the "Show in Drivers Editor" button would
not actually select and highlight the driver under the mouse.
(TODO: The channels still aren't getting selected properly in the
channels list, but at least the properties show correctly)
