Shaking while at the edge of the map has been completely eliminated. In
order to do this, comparison with tile height was also removed which
fixed a few outlier cases.
The main cause was viewport axis were only being set if it's respective
isometric axis was at the boundary, instead of either isometric axis.
Viewport no longer gets stuck which was related to the shaking in the
end. (#2875)
Refactored viewport_update_position. I moved
viewport_set_underground_flag above the bounds checking function since
it had no relation to it. (#996, #2589)
Scrolling on the map edge with arrow keys or mouse edge will now go the
same speed in both directions. (#2254)
Added changelog entry.
When a maze does not have a completely hollowed out hedge the game command would return 0x8000000 as it tries to remove an element that has already been deleted. As game actions no longer use 0x80000000 to indicate a failure this would get interpreted as the refund price and cause the issue.
Fix was to introduce checks when adding up the refund price. This was done rather than changing the game action so that it can be properly fixed when get_refund_price is converted into a game action
When loading a savegame, its filename gets stored as gScenarioFileName.
However, that isn't necessarily the same name as the filename of the
corresponding scenario (or any, for that matter, due to the different
file extension). This broke highscores, so for savegames we have to
take the scenario filename stored in the file.
Title editor sequence selection now defaults to current preset. This is
only after the first time the window is opened. Afterwards it keeps the
last selection.
Land rights tool no longer cares if part of the available land is
unavailable for purchase. It will not even through an error when none of
the tiles are available. Just like other tools.
Added a changelog entry.
This increments the network version.
