Previously, a new 2D vector was allocated for every new frame. This
caused a lot of temporary allocation to be made.
This patch modify "Screen::Clear" so that it do make a new allocation,
but clear the existing one instead.

width and height were being set using the incorrect axes resulting in incorrect canvas dimensions

- Fix focus in flexbox. This required resetting the focus state at the
beginning of the ComputeRequirement(), because it can now run several
times.
This resolves:https://github.com/ArthurSonzogni/FTXUI/issues/399
- Add Box::Union.
- Add a preliminary implementation of forwarding selected_box from
within the flexbox.
The table is not meant to be used to render more than once. Reset the
dimensions so that, even if it is used wrongly, this is not memory
unsafe.

Add decorator variants for decorator components
Add the "pipe" operator for components, similar to what was done for Elements.
We are able to put something like:
```
Button(...) | Maybe(&show_button)
```
Add decorators for:
- `Maybe`
- `CatchEvent`
- `Renderer`

before this change, the example in the doxygen document for CatchEvent()
does not use the documented function. hence the example is not that
useful for developers interested in a typical usage of this function.
after this change, the example is improved to added the call to
CatchEvent(), which allows the application to the Loop() function at
user input.

- Provide better defaults for ComponentBase `Focusable()` and
`ActiveChild()` methods. This resolves:
https://github.com/ArthurSonzogni/FTXUI/issues/335
- Implement `Container::Tab` 's `Focusable()` methods. This prevents
the users to navigate into a tab with no interactivity.
- Add support for SIGTSTP:
https://github.com/ArthurSonzogni/FTXUI/issues/330

- Add support for task posting.
This allows folks to defer function execution, and execute it directly
below the main loop. The task are executed in a FIFO order.
Add the `automerge` attribute to the Pixel bit field. It controls
whether two pixels must be automerged. Defining this allows two
mergeable characters not to be merged.

fix: https://github.com/ArthurSonzogni/FTXUI/issues/296#issue-1092343846
When the list in Radiobox/Menu/Toggle is resized, clamp the |selected_| values so that it stays within bounds.
Clamping is executed in Render() and in OnEvent()

1. the default window size should be 80x24 rather than 80x25 in VT100.
2. the ioctl return value result should be checked. Some operating systems don't support TIOCGWINSZ this command.
Use std::string by default for the implementation of FTXUI's input
component.
Along the way:
- Give a correct implementation for fullwidth characters.
- Add tests
- Modify the way the cursor is drawn.
This implement the flexbox elements, following the HTML one.
Built from them, there is also the following elements:
- `paragraph`
- `paragraphAlignLeft`
- `paragraphAlignRight`
- `paragraphAlignCenter`
- `paragraphAlignJustify`
This is a breaking change.
In case of embedded systems, the terminal size may not
always be detectable (e.g. in case of serial output).
Allow application to set up the default size in case
autodetection fails. On platform such as Emscripten,
there is only "fallback" size.

Msvc defined its own (lowercase) macros for min/max. Because of this, the std::min and std::max functions need to be explicitly included or otherwise are not availible.
In the msvc 2019 compiler this issue seems fixed. However, on msvc 2017 not including <algorithm> causes compilation errors. Adding the include is a simple fix that does not hurt the other platforms and enables compilation on msvc 2017.
This can happen for example in embedded linux, in case
the application is started via serial terminal.

Dom
- `vscroll_indicator`. Show a scrollback indicator on the right.
Component
- `Maybe`: Display an component conditionnally based on a boolean.
- `Dropdown`: A dropdown select list.

- Password is now taking a ref, allowing a shared state to be used by
multiple passwords.
- Password cursor position is now optional. It will be used only when
set to something different from -1.
Screen::ApplyShader accounted for 60% of the computation. This patch
optimize it.
Performance on a 80x80 frame improved from 1400 draw/s to 7000 draw/s.
|hbox| and |vbox| are similar. They are just the same component, but
drawing in a different direction.
This patchs factorize the layout logic. Goal is to reduce code size and
reuse it for the |gridbox| dom element.
Bug: https://github.com/ArthurSonzogni/FTXUI/issues/114
In the past, FTXUI switched from std::string to std::wstring to support
fullwidth characters. The reasons was that fullwidth characters can be
stored inside a single wchar_t.
Then FTXUI added support for combining characters. A single glygh
doesn't even fit a wchar_t. Instead, a glyph can be arbitrary large.
The usage of wstring doesn't really fit the new model and have several
drawbacks:
1. It doesn't simplify the implementation of FTXUI, because of combining
characters.
2. It reduces drawing performance by 2x.
3. It increase Screen's memory allocation by 2x.
This patch converts FTXUI to use std::string internally. It now exposes
std::string based API. The std::wstring API remains, but is now
deprecated.
Tests and examples haven't been update to show the breakage is limited.
They will be updated in a second set of patches.

- Convert Dimension to namespace to allow defining Fit method from dom.
- Use Dimensions extracted from Terminal as replacement struct.
- Convert Terminal to namespace as it only defines static members.
- Remove dom references from screen library (circular dependency).
- Invoke DetachAllChildren from ~ComponentBase
- Define Focused using Active
- Compact TakeFocus loop code
- const-correctness for Parent, Active and Focused
* Reorganize ContainerBase
- Reduce Container overloads using default arguments
- Extract member function pointers to virtual functions
- Separate classes for Vertical, Horizontal and Tab containers
* Collect unpack from NodeDecorator subclasses
* Reduce redundant expansion for aliases
From CppCoreGuidelines:
Rule of Zero: C.20: If you can avoid defining default operations, do.
C.52: Use inheriting constructors to import constructors into a derived class that does not need further explicit initialization.
DRY forward and using declarations.
Miscellaneous:
Fix format.sh to output examples with normalised paths in sorted order.
