Added a new ItemFX type to RichTextLabel which supports dynamic text
effects.
RichTextEffect Resource Type was added which can be extended for more
real time text effects.
It seems to stay compatible with formatting done by clang-format 6.0 and 7.0,
so contributors can keep using those versions for now (they will not undo those
changes).

This allows more consistency in the manner we include core headers,
where previously there would be a mix of absolute, relative and
include path-dependent includes.
This commit makes operator[] on Vector const and adds a write proxy to it. From
now on writes to Vectors need to happen through the .write proxy. So for
instance:
Vector<int> vec;
vec.push_back(10);
std::cout << vec[0] << std::endl;
vec.write[0] = 20;
Failing to use the .write proxy will cause a compilation error.
In addition COWable datatypes can now embed a CowData pointer to their data.
This means that String, CharString, and VMap no longer use or derive from
Vector.
_ALWAYS_INLINE_ and _FORCE_INLINE_ are now equivalent for debug and non-debug
builds. This is a lot faster for Vector in the editor and while running tests.
The reason why this difference used to exist is because force-inlined methods
used to give a bad debugging experience. After extensive testing with modern
compilers this is no longer the case.
- Implement outlines based on FreeType Stroker API. This allows
artifact-free results, similar to what you will see in Web or any text
editing tools. Outline is a part of DynamicFont rather than Label,
because outlines have to be baked into the font's atlas. Font has a
default outline_color and a Label can specify font_outline_modulator
that will be multiplied with the Font's color to get the final result.
- draw_char now has to be called twice to fully render a text - first
with p_outline == true for each character and then with
p_outline == false for each character.
- Number of draw-calls is reduced from 5 to 2 per outlined character.
- Overall cleanup of DynamicFont code, extracted duplicated code pieces
into separate methods.
- The change is backward-compatible - Labels still have outline
properties that work exactly as they worked before.
Closes#16279.
