Change: Hide bevel for resizeable sparse layout windows. (#11572)

When clicked, the button is still highlighted to show that it is active.

The bevel is controlled with widget_data by RWV_SHOW_BEVEL or RWV_HIDE_BEVEL values.

Fix: Prevent overflow when calculating max town noise (#11564)

Max town noise could overflow if the population was high enough. The value is now clamped.

Fix #11352: Draw all network server info as multiline strings. (#11567)

This also allows the 'header' (which is not actually a widget) to grow
as necessary to fit the server name.

Fix: AirportGetNearestTown incorrectly assumed first TileIterator result was origin. (#11565)

Not all TileIterators are equal, and some do not start at the top-corner, so the perimeter check was wrong. As the caller already has thie origin tile, use that instead.

Fix: Ensure saveload type match variable type.

This either changes the saveload definition or changes the variable depending on which makes more sense.

Codechange: Don't keep autosave_interval in std::chrono::minutes.

This variable is saved as a setting which requires the variable type to be known, but std::chrono::minutes may vary depending on system type.

Instead, keep as uint32_t and convert to std::chrono::minutes only when setting the timer.

Codechange: Move dropdown list size and position calculation to window.

This simplifies initialization of DropdownWindow, as instead of both the caller code and the class needing to know about list sizes and available space, only the DropdownWindow needs to know.

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.

Fix: Don't implicitly ReInit all windows after updating the character width cache.

This caused duplicate ReInit when changing interface scale.

Fix #11556: Missing saveload change for OrderBackup. (#11557)

Apply the saveload change from #11468 to OrderBackup and bump again.

Fix #11551, aab580e0a: Link graph job results were incorrectly applied (#11558)

Edge flows were incorrectly restricted because the restricted
instead of unrestricted last update date was checked

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

This avoids contorting fullbevel dimensions.

Codechange: Vertical spacing for caption is captiontext, not framerect. (#11550)

This does not really matter as the caption height is sized correctly later anyway, so this just avoids confusion.

This restores original behaviour, and prevents all image buttons being slightly too large.

Change: Show rating in station list even with no cargo waiting. (#11540)

e745bd9 (r21144) changed the filter from cargo waiting to rating, which makes the station list display appear inconsistent with the cargo filter selection.

Fix: Make station list filters use per-window state instead of global state.

Changing filters with multiple windows open would have unexpected effects leading to inconsistent state.

Now state is loaded and saved when the window is opened and closed, so state is still persistent.

Codechange: Optionally allow passing state to GUIList sorter function.

GUIList sorter functions can currently only use global state, which makes per-window-instance sorting difficult.

Feature: (-tte) Add zoom level buttons to sprite aligner.

This allows for offsets to be adjusted a different zoom level than currently in use, and offset adjustment and display is also more convenient.

Codechange: Rearrange AI/GS debug window following invalidate/set state/draw pattern. (#11483)

The AI/GS window updated its state as it was drawn, and would redraw again if some state had changed.

Instead, update state either during OnInvalidateData or before any drawing commences.

Add: Website button to Game Options window for basesets.

This links to the optional "url" item in the baseset's [metadata] section.

Change: Hide unused cargos from vehicle cargo filter. (#11533)

The list of used cargo types is updated when the list is invalidated.

Remove: officially mark Vista as no longer supported (#11531)

It is very likely Vista hasn't been working for years, but the
amount of users that use an OS that has been EoL for over 11 years
is very small, so reports happen rarely.

Feature: Place cargo icon on cargo filter dropdowns.

Reveal the pixel art.

Codechange: Add DropDownIcon constructor to override dimension.

This avoids the need to construct a DropDownIcon and set the dimension after.

Change: Use CRTP-mixins to compose dropdown list items.

This allows list items to built from component parts as required, and additional
functionality is added:

* Icons and text can be positioned at the start or end of the space (templated.)
* Font size of text can be changed (templated.)
* Palette of sprites can be set (runtime.)

Codechange: Dimension must have both width and height.

Default parameters allowed Dimension to be constructed with only a width.

Instead use separate empty and width/height constructors to ensure that either none or both are provided.

Change: Add extra padding to climate buttons to match pre-#11464. (#11525)

Padding used to be included in the SetMinimalSize() part which was removed, but also made it require specific sprite sizes.

This now adds padding on the already determined size, removing the need for hardcoding pixel dimensions and allowing the sprites to be any size.

Codechange: Make a generic DrawRectOutline function from DrawOutline. (#11524)

This allows drawing an outline from Rect, not just constrained to a Widget's Rect. And reduces duplication a little.

Remove: ZOOM_LVL_COUNT

This is the only enumeration with a COUNT and END. The logic of the COUNT
implied that BEGIN could be non-zero, but all but two uses of zoom level
assume that BEGIN is zero, making the separate count only confusing.

Feature: Randomize direction of rail vehicle on build based on probability callback. (#11489)

This allows NewGRF authors to indicate that the game should randomly flip rail vehicles on build, without needing to use random bits nor duplicate sprites to handle it themselves.

To use this functionality, test for callback 162 (CBID_VEHICLE_BUILD_PROBABILITY) and var10 = 0 (values other than 0 are reserved for future use), and return a value between 0 and 100 inclusive.

The return value is a percentage chance of reversing the vehicle. A value of 0 will always build a forward facing vehicle, and 100 will always build a reverse facing vehicle.

Fix ab1a4c6c: Crash if the "No Music" set is loaded because there is no current set_index. (#11511)

Add a helper function to get the current set_index which which checks it is in range.

Codechange: Use range-for to simplify getting first non-zero value.

This reduces indexed array access.

Codechange: Be consistent with how we name common parameters

TileIndex is always tile and Town is always *t. Don't use t and *town.

Codechange: Rename TryClearTile() for clarity

The function does not execute the clearing action.

Codechange: Use consistent name for bay road stops

As of #10494, this is how we describe original dead-end road stops.

Fix ab1a4c6c: Changing baseset/playlist while shuffle is on does not change song. (#11510)

The change-playlist function relied on toggling shuffle to restart playing which is no longer the case, so always handle it when changing playlist instead.

Fix #10926: New free wagons no longer split by type. (#11507)

NormalizeTrainVehInDepot() should only be called if an engine was built, not for wagons.

Codechange: Template input buffer type in audio mixer. (#11505)

This reduces code duplication.

Codechange: Use std::array for industry tile cargo acceptance. (#11498)

This avoids use of memcpy/memset to copy or fill.

Change: Don't restart playback when toggling playlist shuffle.

Instead update the selected playlist entry for the current song.

Change: Try stopping extmidi player with SIGINT first. (#11404)

This may give the player a chance to issue MIDI note-off commands.

The kill/waitpid cycle is also less aggressive, waiting 50ms each time.

Fix #11500: Rename Textfile GUI's LinkType to HyperlinkType. (#11502)

This disambiguates it with LinkType in league tables.

Fix: Add shading to river slopes

Adds a 32bpp shading to the river rapids/slopes to make them more visible. Requires a bump of original graphics grfs to use container version 2. Fixes #9031

Change: Set height of larger heightmap/scenario worldgen buttons by text height. (#11496)

This allows the button height to scale properly by font size.

Change: When building NewGRFs, use grfid (from grfcodec) to calculate NewGRF MD5 hash. (#11492)

This allows for v2 container NewGRFs to be created. Hashes are needed for building the baseset metadata, so the .hash files are stored the source tree so they can be built if grfcodec and grfid are not present.

The hash of openttd.grf is not actually needed, but it is simpler to leave it in than handle only orig_extra.grf.
