has AI companies.

Fix: virtual call from constructor

That fills an instance variable that is only read from the Game Options window
and that is overwritten when the video driver is started. Since you cannot get
into the Game Options window without starting the video driver, it is just
pointless and wrong code that would never be noticed by the end user.

Fix: bad oddness checks

Modulo on a signed number returns negative values for negative values, so
i % 2 == 1 will only return true for positive odd numbers, whereas i % 2 != 0
returns true for both positive and negative odd numbers.

Codechange: silence some potentially uninitialized local variable errors

In these cases technically they are false positives, however dismissing the
alerts when the underlying code may make them true positives does not seem
like the safest solution.

Fix: inconsistent allocation error handling

Mix-and-matching std::bad_alloc exception handling with nullptr checks

Fix: comparison of narrow type with wide type in loop condition

Technically this can't be triggered with the currently returned values though.

Fix: Don't assume engclass 2 should be elrail. (#10315)

When disabling/enabling elrail, there is an assumption that `engclass` of 2
means the engine will run on elrail. While this holds for default engines,
NewGRFs can do other things.

To resolve this we store the intended railtype so that toggling elrail will
restore to the correct type.

Codechange: address CodeQL issue "Multiplication result converted to larger type" (#10306)

Most are very unlikely to ever be triggered in our codebase; two
stand out: linkgraph and money cheat. Those, potentially, could
wrap earlier than expected.

Fix #10220: Adding unavailable variants failed for non-rail engines. (#10297)

Unavailable parent variant engine for non-rail engines was added to the
wrong (temporary) list so the hierarchy was not added correctly.

Fix: Local authority window rating list height ignored icon sizes. (#10285)

Only font height was taken into account, so the list was broken if icon
sizes were taller than font height.

Fix #10224: Don't fiddle with fast-forward when saving. (#10230)

The original comment about saving with fast-forward on was written 18 years
ago, and predates lots of changes to how saveload work.

Change: Add extra random seed to StartupEngines().

This means that calling reset_engines will rerandomise introduction dates
and reliability.

Probably not necessary.

Change: Mark build/autoreplace windows dirty less often in monthy loop.

These window classes were marked dirty for every engine that had
reliability calculated every month.

Feature: Vehicle add-ons can now group engines in purchase list.

Grouped engines are collapsed by default but can be expanded. This allows
similar engines to be grouped together to avoid cluttering the list.

Suggested uses for this are e.g.:
* Liveries; same stats but different paint job.
* Re-gearing; engine design is mostly the same but different stats.

... but avoiding complex hidden cargo subtype refit systems.

Grouped engines are otherwise separate, so can be independently
autoreplaced, even between variants.

Fix #10150: Force FS_SMALL for small viewport signs. (#10283)

* Fix #10150: Force FS_SMALL for small viewport signs.

This is a workaround for string widths being different with mixed
font-sizes.

* Fix: Flag small sign shadow as small text.

(This method of drawing shadows is hilarious and needs replacing, but
this is a quick fix.)

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: Support flipping shorter engines without NewGRF support. (#10262)

* Change: Support flipping shorter engines without NewGRF support.
* Cleanup: Remove write-only prop27_set temporary flag.

Cleanup: Replace foundation drawing magic numbers.

Use TILE_SIZE or TILE_HEIGHT as appropriate instead.

Fix: Wrong type cast for selected AI/GS script info in AIListWindow

This resulted in technically undefined behaviour when listing GSs

Fix #10151: Use smaller padding for viewport signs. (#10272)

Before variable-scaling, the padding was always 1x1 pixel. This was
changed to be scaled, except using the wrong dimension of 2x1 pixels
instead of 1x1 pixel.

Fix: Incorrect available height for dropdowns due to unsigned promotion. (#10264)

Dropdowns which are taller than the main window should automatically have
a scrollbar added. This did not work for toolbar dropdown as the location
near the top of the window resulted in an unsigned underflow.

Change: Use lowered not disabled widget for current tab. (#10252)

While tab-buttons are not often used, all other similar occurences use
lowered rather than disabled widgets, so use them for train detail
window too.
