Add: 32bpp-to-8bpp palette index lookup.

Lookups are calculated on demand and caches in a 256KB in-memory table.

Codechange: Perform simpler comparison first when checking for palette updates.

This avoids unnecessarily comparing contents of an array.

Change: Remove hardcoded minimum sizes and allow resize.

This stops the window being needlessly large.

Change: Move colour selection dropdowns to bottom of window.

This stops them looking similar to how filter controls are used elsewhere,
and matches action dropdowns on other windows.

Fix #11442: "default" colour in group colour window is not updated when changing master colour (#11614)

Updated SelectCompanyLiveryWindow.DrawWidget method to check if a group's livery.in_use 0 bit is set, rendering the company's default colour if it has not been.

Fix #11515: Zoom level could wrap around when changing interface scale. (#11615)

This happened due to converting the new value to unsigned before clamping instead of after.

Fix: Update widget dimensions before updating viewport signs. (#11611)

Viewport signs used fullbevel WidgetDimensions before it was updated for the new interface scale.

Codechange: Replace pointer to Sprite array with reference to SpriteCollection. (#11580)

Add `SpriteLoader::SpriteCollection` type which is an array of `SpriteLoad::Sprite`.

This removes the ambiguity of what `SpriteLoader::Sprite *` is pointing to,
and cleans up mismatches using both dereference -> and array access [] for the
same object.

Fix: Draw unavailable mask over picker sprite instead of behind it.

This makes these disabled picker buttons consistent with other disabled buttons.

Codechange: Add Rect version of FillDrawPixelInfo().

This simplifies most callers as they longer have to split out a rect.

Fix #10452: Don't let AyStar max_search_nodes unattended when initializing (#11544)

Add a constant with the default value of 10000 and have the pathfinding settings refer to it.

Add a preventative method to AyStar when it's initializing, to limit the number of max_search_nodes if left unattended.

Change: Don't mention TerraGenesis in setting helptexts

We no longer show the land generator in the World Generation GUI, so this is less important to explain in tooltips.

Fix #11585: Crash when cleaning AI/GS with nested AsyncMode.

Do not throw sanity check when in_shutdown is true. This is also applied to
ExecMode and TestMode as they follow the same pattern.

Codechange: Use MakeParameters with GetNextParameter in FormatString (#11583)

Instead of StringParameters subspan, to avoid GSs being able to
cause subspan boundary assertion failures

Codechange: Cargo filters no longer take an index. (#11582)

Update naming of functions to reflect that parameter is now a cargoid.

Fix #11577: Extra viewport opened in wrong location. (#11578)

ExtraViewportWindow calls IninitializeViewport() with focus as 0, which is ambiguous as focus should be either a TileIndex or a VehicleID.

Instead, pass the tile and let InitializeViewport() handle setting all the coordinates.

Change: Be selective about clearing sprite/font caches on interface scale change. (#11576)

Sprite cache contains all zoom levels anyway, so does not need to be reloaded.

Font cache does not need to be clear if the font zoom hasn't changed, i.e. when changing the max sprite zoom level setting.

Fix e2425b7: Sprites no longer refreshed if max zoom level changed.

Handle this via AdjustGUIZoom() instead.

Fix e2425b7: WidgetDimensions and depot sizes not set up if blitter forced.

Set up WidgetDimensions and depot sizes during InitWindowSystem().

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.

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.
