Codechange: Use named initialization for unscaled WidgetDimensions. (#11859)

Remove now-unused WD_* enums.

Fix #11649: Ignore disabling a widget that does not exist. (#11652)

Orders window has different widget layouts depending on vehicle type
which don't all have the same widgets, and therefore it tries to disable
widgets that might not exist.

Restore the old behaviour of ignoring such requests, instead of crashing.

Codechange: Replace mishmash of types for widget index with WidgetID.

Indices were stored as int, but often passed around as uint/uint8_t and casts.

Now they should all use WidgetID.

Codechange: Use std::map to provide indexed widget access.

This removes the need to determine the biggest widget index and replaces C-style memory handling.

Codechange: Rename nested array to widget lookup.

This changes from naming storage-type to naming functionality.

* `FillNestedArray` is renamed to `FillWidgetLookup`.
* `Window::nested_array` is renamed to `Window::widget_lookup`.
* `array` parameter renamed as well.

Codechange: Remove deferred nested_array initialization path. (#11640)

Having two ways (`FillNestedArray` and `SetupSmallestSize`) to initialize
`Window::nested_array` introduces confusion.

Instead, make `FillNestedArray` the canonical way, always call it, and remove
init_array from `SetupSmallestSize`.

Fix #11516: Adjust window size by interface scale during ReInit.

To simplify this and ensure that scaling only occurs once, regardless of
resize nesting, each window now remembers interface scale.

Codechange: Add specific WidgetDimension for dropdown list window. (#11554)

This avoids contorting fullbevel dimensions.

Add: WidgetDimensions for 'sparse' widget windows.

These are for windows that have space between widgets instead of being clumped together.

Codechange: Add base() method to StrongType to allow access to the base type without casting. (#11445)

This removes the ability to explicitly cast to the base type, but the requirement
to use .base() means the conversion is still explicit.

Codechange: Add __FILE__/__LINE__ of WindowDesc to WindowDesc.

This is to allow unit-tests to produce more useful output.

Add: data parameter in Window::Close method.

This allows passing data when closing a window, e.g. to indicate how it was closed.

Codechange: Use begin/end of nwidget parts of begin/length.

This simplifies processing nwidget parts as, unlike the remaining length, the pointer to the end of the list never changes. This is the same principle as we use(d) for tracking end instead of length for C-style strings.

And this removes 160~ instances of the lengthof() macro.

Codechange: make explicit when a TileIndex is cast to its basetype (#11190)

This prevents people accidentially assigning a TileIndex to a Date
or any other type they shouldn't.

Codechange: automatic adding of _t to (u)int types, and WChar to char32_t

for i in `find src -type f|grep -v 3rdparty/fmt|grep -v 3rdparty/catch2|grep -v 3rdparty/opengl|grep -v stdafx.h`; do sed 's/uint16& /uint16 \&/g;s/int8\([ >*),;[]\)/int8_t\1/g;s/int16\([ >*),;[]\)/int16_t\1/g;s/int32\([ >*),;[]\)/int32_t\1/g;s/int64\([ >*),;[]\)/int64_t\1/g;s/ uint32(/ uint32_t(/g;s/_uint8_t/_uint8/;s/Uint8_t/Uint8/;s/ft_int64_t/ft_int64/g;s/uint64$/uint64_t/;s/WChar/char32_t/g;s/char32_t char32_t/char32_t WChar/' -i $i; done

Change: Add window description flag to disallow interactive window closing. (#11008)

This replaces/simplifies testing for a closebox to allow closing a window with right-click, and testing for specific window classes when closing all windows by hotkey.

This allows right-click closing of dropdowns and the high-score window.

Fix #10987: Double-close of dropdown stopped land-info tool working as default. (#11000)

Clicking and releasing on the query toolbar icon is meant to select the land-info tool.

This did not work as during closing a window, OnFocusLost() is called, which then closes the window again. These two calls toggled the land-info tool one and off in the same action.

Resolve by not calling Window::Close in OnFocusLost() if the window is already closing.

Codechange: C++-ify the Layouter and related functions

They all now access a std::string_view, instead of a "const char *"
or std::string (in some cases).

Additionally, GetCharAtPosition and friends now return an index
instead of a "const char *", as it makes for a more clear interface.

Change: include fmt.h C++ headers in stdafx.h

This to prevent compilation issues between runs with and without precompiled
headers. Also remove the headers from the rest of the code base as they are
not needed there anymore, although they do relatively little harm.

Change: Rename text colour NWidgetPart to SetTextStyle and add font size.

This allows to set both text colour and size for any widget with default
drawing.

Codechange: migrate all Window-related timers to the new framework

This means we also say goodbye to GUITimers.

Fix #8971: Resize QueryStrings with interface scale change. (#10281)

* Fix: Use width of caret symbol '_' for text entry.

This replaces an arbitrary pixel width with the space actually required.

* Fix #8971: Update QueryString sizes with interface scale change.

Change: Standardize progress bar layout.

Progress bars are drawn differently depending on when it was added, with
different layouts and sizes.

This change adds a standard padding size to use, and makes all progress
bars visually similar, with scaled padding.

Change: Split vscroll and hscroll padding.

Vertical and horizontal scrollbars are different sizes, this allows
different padding for each type.

Add: Define scaled WidgetDimensions.

Includes RectPadding container.

Codechange: use IterateFromBack/Front only if the order is important.

Use Iterate if the order does not matter.

Codechange: use iterators instead of 'subranges' when iterating from a specific window.

Using iterators makes it easier to include or exclude the start window in the iteration.

Codechange: remove excessive templating in favour of a single const_cast.

The const_cast will be removed again in a later commit.

Codechange: Spell 'Viewport' consistently

Some places in the codebase misspell 'Viewport' as 'ViewPort' or 'view_port'.
This patch makes everything consistent.

Fix 801cbea9c: operator< is not always the best idea

Also removes unused and anyway broken SmallMap::SortByKey() function.

Codechange: Implement OnTooltip event for custom window tooltips.

This avoids windows from needing to know or care about tooltip delay settings.

Fix #7386: Measurement tooltip for tunnels, aqueducts & docks did not display or flickered.

Measurement tooltip was auto-closed as the hover/right-click test for tooltips was not
satisfied in this case. This is fixed by keeping the tooltip visible and instead explicitly
closing the tooltip when the PlaceObject is cancelled/completed.

Codechange: Change scrolling_scrollbar to mouse_capture_widget, and dispatch OnClick() event if widget is not a scrollbar.

This allows any widget to support mouse capture.
