For example, if you have a config that defines OpenGFX as baseset
but for some reason you have no basesets anymore. In that case
bootstrap downloads OpenGFX for you, but it will still show the
error that "OpenGFX was not found" after the bootstrap. This was
an error generated before the bootstrapped kicked in.
Simply muting all errors during bootstrap solves this; as we cannot
show them anyway, this is fine. Any errors that remain after
bootstrap will be generated again anyway.
There are various of ways bootstrap can fail:
- Failing network connection
- Incomplete download
- No write permissions
- Disk full
- (others I forgot)
They all result in a screen with no windows. To ensure we at least
always show something when anything bad happens, if the bootstrap
is not successful, show a screen what the next step for the human
should be.

This means if you execute a script from a script from a script, ..
for more than 10 times, it bails out now. This should be sufficient
for even the most complex scripts.
MaskWireBits always returns its input unchanged if the input
has only 0 or 1 track bits set.
Having only 0 or 1 track bits sets (i.e. non junction tiles)
is by far the most common case.
Examining the state of neighbouring tiles and the subsequent
masking logic is relatively expensive and can be omitted in this case.
It didn't sit well to me, how I wrote the commit initially. First
casting a variable into another, only to write it back into the
originally feels wrong.
This flow makes a bit more sense to me.
Otherwise that might cause calls to the video-driver, which are
already shut down by now. This causes, depending on the video-driver
crashes or weird effects.
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.

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.
