Clang-format sees the text behind `#pragma region` as code and formats it. Instead of stating the copyright and date there, it's now in the comment block right below it. The text "Copyright" is left in the `#pragma region` line, as clang-format sees it as a single identifier.
I took the opportunity to normalize the dates, and add the copyright notice to the source files where it was missing them (except for third-party and the generated resources.h file).
Stop previewing sequence now unfollows the current sprite.
Using the arrow keys in-game cancels following.
Resizing the window no longer cancels following.
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.
