This commit includes several performance, stability, and reliability
improvements to cloth collisions.
Most notably:
* The implementation of a new self-collisions system.
* Multithreading of collision detection.
* Implementation of single sided collisions and normal overrides.
* Replacement of the `plNearestPoints` function from Bullet with a
dedicated solution.
Further, this also includes several bug fixes, and algorithmic
improvements.

Terms get/set don't make much sense when casting values.
Name macros so the conversion is obvious,
use common prefix for easier completion.
- GET_INT_FROM_POINTER -> POINTER_AS_INT
- SET_INT_IN_POINTER -> POINTER_FROM_INT
- GET_UINT_FROM_POINTER -> POINTER_AS_UINT
- SET_UINT_IN_POINTER -> POINTER_FROM_UINT
Also minor changes:
- Remove unused headers.
- rename SimpleExprParseState -> ExprParseState
- rename max_ops -> ops_count_alloc
Was misleading since maximums are often limits which can't be exceeded.
Simple isn't a good prefix for library names since
lots of unrelated modules could be called 'simple'.
Include 'py' in module name since this is a subset of Python,
one of the main motivations for this is to be Python like/compatible.
The goal here is to make app templates usable for default templates
that we can ship with Blender. These only have a custom startup.blend
currently and so are quite limited compared to app templates that fully
customize Blender.
But still it seems like the same kind of concept where we should be
sharing the code and UI. It is useful to be able to save a startup.blend
per template, and I can imagine some scripting being useful in the future
as well.
Changes made:
* File > New and Ctrl+N now list the templates, replacing a separate
Application Templates menu that was not as easy to discover.
* File menu now shows name of active template above Save Startup File
and Load Factory Settings to indicate these are saved/loaded per
template.
* The "Default" template was renamed to "General".
* Workspaces can now be added from any of the template startup.blend
files when clicking the (+) button in the topbar.
* User preferences are now fully shared between app templates, unless
the template includes a custom userpref.blend. I think this will be
useful in general, not all app templates need their own keymaps for
example.
* Previously Save User Preferences would save the current app template
and then Blender would start using that template by default. I've
disabled this, to me it seems it was unintentional, or at least not
clear at all that saving user preferences also makes the current

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.

They way Blender handles vertical alignment is very buggy:
- Top-Base: It works perfectly.
- Bottom: It is actually bottom-baseline,
and it fails when line size is != 1.0 when working with text boxes.
- Top: Poorly implemented, it should use font's ascent
(recommended distance from baseline),
so it has room for accents,
but it's not one line distance far from the origin (as it is now).
- Center: Poorly implemented.
This is tricky since there is no silver bullet.
To clear this situation I created a new option (Bottom-Baseline),
and addressed the issues above.
I'm getting the ascent and descent from freetype2,
and use this for padding above/below the text.
Also for vertically centering the text.
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.
Damped Track by specification attempts to arrive at the desired
direction via the shortest rotation. However with opposite vectors
there are infinitely many valid 180 degree rotations. Currently
it gives up and does nothing.
I think that it would be more reasonable to resolve the ambiguity
arbitrarily, so that Damped Track won't have a weird dead zone.
To make it more predictable I use a local axis.
In addition, the singularity area vicinity has some floating
point precision problems that result in significant jitter.
This applies workarounds for two causes of instability.

This patch adds a new matte node that implements the Cryptomatte specification.
It also incluces a custom eye dropper that works outside of a color picker.
Cryptomatte export for the Cycles render engine will be in a separate patch.

There were two issues here, introduced by rB66aa4af836:
* Forgot to change length of some filter_glob var deep in filebrowser code.
* Truncating filter_glob in general can be dangerous, generating
unexpected patterns.
Last point was the root of the issue here, truncating to 63 chars string
left last group as 'match everything' `*` pattern.
To fix that to some extent, added a new BLI_path_extension_glob_validate
helper to BLI_path_util, which ensures we do not have last
wildcards-only group in our pattern, when there are more than one group.
