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.

Codechange: List toolbar menu items and dividers explicitly.

This makes it clearer what items will be shown in the list, allows for non-consecutive
string IDs, and means unused enum values are not necessary.

Fix 7cfcf65: Check if last-remembered build vehicle cargo filter is valid. (#11486)

This can be invalid when switching between games with different cargoes loaded.

Fix: Restore original cargo legend 'blob' dimensions. (#11480)

An off-by-one in a previous life made the 'blob' too narrow.

Codechange: Remove FONT_HEIGHT_... macros. (#11481)

These make it look like we're dealing with a constant, but actually each is a call to `GetCharacterHeight(...)`.

Fix 96d98d08: Crash in text layouter due to trying to find height of string with zero-width.

96d98d08 removed the hardcoded minimum width in favour of all-calculated widths, however this does not work when determining multiline text sizes.

Codechange: Add method to guess the width/height required for a multiline string.

This is necessary for widget layouts where a minimum width is not yet known during UpdateWidgetSize().

Codechange: Assert that max width passed to GetStringHeight is non-zero.

Max width of zero will cause text layouters to crash, potentially after exhausting memory first.

Fix: Trivial autoreplace of mixed cargo articulated engines (#11253)

Do not fail autoreplace/autorenew of mixed cargo articulated engines
due to an inability to refit to mixed cargoes, when no refit is
required because the target engine already has a suitable set of cargoes.
Notably, this allows autorenew (autoreplace to same engine type)
to succeed.

Codechange: Simplify setting minimum width for game options dropdown lists. (#11474)

Height isn't necessary as drop down controls already have sufficient height, so we can use GetDropDownListDimension() to get the width.

Codechange: Remove now-unnecessary containers in picker layouts. (#11473)

These are no longer necessary as the issue they work around was resolved by #11471

Fix: Extra space allocated to container-within-container may not get allocated to children. (#11471)

Always derive additional length from contained widgets instead of from the container, as the container's minimal length may have been adjusted by an NC_EQUALSIZE parent container.

Fix: extmidi did not move on to next song after playing ends. (#11469)

`song` is no longer a C-style string so cannot be cleared by writing a NUL char.
Use `.clear()` to properly clear a std::string.

Codechange: Move RectPadding::zero definition to header. (#11461)

This potentially allows better inlining/optimization.

Codechange: Simplify cargo filter lists, building only when required.

Some cargo filter lists were built in advance, and used as lookups to test which cargo type to filter.

Instead, use the Cargo ID directly as the filter parameter, and build the lists only when the drop down list is used.

Codechange: Simplify autoreplace rail/road types by using separate widget. (#11457)

This avoids needing to determine which type of list to deal with by additionally checking the window number for VEH_TRAIN/VEH_ROAD.

Change: Move baseset missing/corrupted files label to list item. (#11455)

This allows any baseset error to be displayed in the drop down list so it is more easily visible, and avoids wasted space in the layout.

Codechange: Replace AllocatedStringParameters with ArrayStringParameters (#11452)

All uses of AllocatedStringParameters are with a compile-time fixed
constant.
Use of a dynamically allocated buffer on the heap is unnecessary and
increases overhead, particularly due to frequent use as a temporary.

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.

Change: Add horizontal scrollbar to Industry Directory window.

This list could be very wide depending on industries and language.

Codechange: Don't filter industry list by cargo type every 3-sec refresh.

The 3-sec refresh is to update the list sorting. The filter only needs to
be applied once rebuilding the list.

Codechange: Skip invisible (zero-size) widgets in PIP Containers.

This gets rid of doubled-up spacing where an invisible child widget would be.

Codechange: Add ability to allocate PIP-space dynamically by ratio.

This can be used to space out, centre, start-align, or end-align widgets without additional spacers.

Fix #11437: Flipped shorter rail vehicles disappear in windows. (#11446)

Mixed signed/unsigned strikes again, causing an incorrect sprite offset for shortened vehicles.

Codechange: Don't be lenient with invalid NWidgetPart lists.

Some NWidgetPart combinations were ignored but it was not clear that they do nothing. Instead, assert if NWidgetPart is incorrectly applied.

Add: Mock sprite cache intialization.

This fills up the sprite cache with SPR_OPENTTD_BASE + OPENTTD_SPRITE_COUNT zero-size sprites, to
allow GetSpriteSize() calls to continue from unit-tests.

Add: Expose minimal parts of SpriteCache internals.

These parts are needed to be able to mock the SpriteCache for unit-tests.
