This prevents the window from "freezing" when you close it during
the scanning of NewGRFs, as it first would continue the action.
|
|
Otherwise the numbers are all over the place when a modal window
just closed.
|
|
Basically, modal windows had their own thread-locking for what
drawing was possible. This is a bit nonsense now we have a
game-thread. And it makes much more sense to do things like
NewGRFScan and GenerateWorld in the game-thread, and not in a
thread next to the game-thread.
This commit changes that: it removes the threads for NewGRFScan
and GenerateWorld, and just runs the code in the game-thread.
On regular intervals it allows the draw-thread to do a tick,
which gives a much smoother look and feel.
It does slow down NewGRFScan and GenerateWorld ever so slightly
as it spends more time on drawing. But the slowdown is not
measureable on my machines (with 700+ NewGRFs / 4kx4k map and
a Debug build).
Running without a game-thread means NewGRFScan and GenerateWorld
are now blocking.

gui_zoom was never clamp'd between zoom_min/zoom_max.
zoom_min controls how zoomed-in we load sprites. For a value of 1,
no quad-sizes sprites are loaded. If gui_zoom would be 0, meaning
it wants quad-sized sprites to display, it was printing random
stuff to the screen, which could or could not result in crashes.

Otherwise both the draw-thread and game-thread can do it both
at the same time, which gives rather unwanted side-effects.
Calling it from the draw-thread alone is sufficient, as we just
want to create some unpredictable randomness for the player. The
draw-thread is a lot more active (normally) than the game-thread,
so it is the best place of the two to do this.
Additionally, InteractiveRandom() mostly has to do with visuals
that are client-side-only, so more related to drawing than to
game.

v->tile for aircrafts is always zero when in the air. Only when
it starts its landing (or take-off) patterns it becomes a sane
value.
So instead, base the news on the last x/y coordinates of the plane.

As OpenTTD grew, we found other ways to do this, and we are no
longer in need for a hack like this.

This because video-drivers might need to make changes to their
context, which for most video-drivers has to be done in the same
thread as the window was created; main thread in our case.

This allows drawing to happen while the GameLoop is doing an
iteration too.
Sadly, not much drawing currently can be done while the GameLoop
is running, as for example PollEvent() or UpdateWindows() can
influence the game-state. As such, they first need to acquire a
lock on the game-state before they can be called.
Currently, the main advantage is the time spend in Paint(), which
for non-OpenGL drivers can be a few milliseconds. For OpenGL this
is more like 0.05 milliseconds; in these instances this change
doesn't add any benefits for now.
This is an alternative to the former "draw-thread", which moved
the drawing in a thread for some OSes. It has similar performance
gain as this does, although this implementation allows for more
finer control over what suffers when the GameLoop takes too
long: drawing or the next GameLoop. For now they both suffer
equally.

There really is no need to make an extra call to the OS in
these cases.

Drawing in a thread is a bit odd, and often leads to surprising
issues. For example, OpenGL would only allow it if you move the
full context to the thread. Which is not always easily done on
all OSes.
In general, the advise is to handle system events and drawing
from the main thread, and do everything else in other threads.
So, let's be more like other games.
Additionally, putting the drawing routine in a thread was only
done for a few targets.
Upcoming commit will move the GameLoop in a thread, which will
work for all targets.

Basically, the window was not invalidated, so it was never redrawn.
This made it look like it wasn't working, but it really was.

The video drivers using the OpenGL backend are currently our only
accelerated drivers. The options defaults to off for macOS builds and
to on everywhere else.

Reworked how the screenshot command works while keeping it backwards
compatible. It can now more freely understand arguments, and has
the ability to make SC_DEFAULTZOOM screenshots.

relation (#8801)
In other words, it should only (!) return true if A comes for B.
This promise was broken for the situation where two values are
identical. It would return true in these cases too. This is of
course not possible: if two values are identical, neither come
before the other. As such, the sorter was not imposing strict
weak ordering relations.
libstdc++ handled this scenario just fine, but libc++ crashes
badly on this, as it allowed comparing of [begin, end] instead
of [begin, end).
libc++ considered this not a bug (and by specs, they are correct;
just this way of crashing is of course a bit harsh):

This affected all screenshot types that render to an off-screen
buffer and don't copy the actual screen contents.

This is an easy mistake to make, so protect us against making such
mistakes, by validating it doesn't happen.

So any old game made with this setting was overflowing anyway;
not really a lot we can do about that now.

The bootstrap has the _switch_mode to SM_MENU, and never leaves
this mode. Neither is it considered a modal window (while in some
sense it really is). So .. we need to add another "draw anyway"
exception, to make sure bootstrap is being drawn.
