19fdbac287 Fix: [Win32] now we are drawing on a tick, no longer use WM_PAINT 
WM_PAINT hits when-ever Windows feels like, but always after we
marked the screen as dirty. In result, it was lagging behind,
giving a sub-60fps experience.

With the new draw-tick there is no longer a need to be driven by
WM_PAINT, so it is better anyway to drive the drawing ourself. As
an added bonus this makes the win32 driver more like the others.

c4df0f95ae Fix: during switching of game-mode, drawing could show closed windows that shouldn't be closed yet 
The higher your refresh-rate, the more likely this is. Mostly you
notice this when creating a new game or when abandoning a game.

This is a bit of a hack to keep the old behaviour, as before this
patch the game was already freezing your mouse while it was changing
game-mode, and it does this too after this patch. Just now it
freezes too a few frames earlier, to prevent not drawing windows
people still expect to see.

fa170b9ace Feature: configurable refresh-rate and change default to 60fps 
Most modern games run on 60 fps, and for good reason. This gives
a much smoother experiences.

As some people have monitors that can do 144Hz or even 240Hz, allow
people to configure the refresh rate. Of course, the higher you
set the value, the more time the game spends on drawing pixels
instead of simulating the game, which has an effect on simulation
speed.

The simulation will still always run at 33.33 fps, and is not
influences by this setting.

eb9b1ad68d Change: sleep till the next tick in the main loop 
Sleep for 1ms (which is always (a lot) more than 1ms) is just
randomly guessing and hoping you hit your deadline, give or take.

But given we can calculate when our next frame is happening, we
can just sleep for that exact amount. As these values are often
a bit larger, it is also more likely the OS can schedule us back
in close to our requested target. This means it is more likely we
hit our deadlines, which makes the FPS a lot more stable.

ae7a2b9f02 Change: allow video-drivers to miss deadlines slightly 
Before, every next frame was calculated from the current time.
If for some reason the current frame was drifting a bit, the
next would too, and the next more, etc etc. This meant we rarely
hit the targets we would like, like 33.33fps.

Instead, allow video-drivers to drift slightly, and schedule the
next frame based on the time the last should have happened. Only
if the drift gets too much, that deadlines are missed for longer
period of times, schedule the next frame based on the current
time.

This makes the FPS a lot smoother, as sleeps aren't as exact as
you might think.

c81c6e5eb7 Add: draw the screen at a steady pace, also during fast-forward 
During fast-forward, the game was drawing as fast as it could. This
means that the fast-forward was limited also by how fast we could
draw, something that people in general don't expect.

To give an extreme case, if you are fully zoomed out on a busy
map, fast-forward would be mostly limited because of the time it
takes to draw the screen.

By decoupling the draw-tick and game-tick, we can keep the pace
of the draw-tick the same while speeding up the game-tick. To use
the extreme case as example again, if you are fully zoomed out
now, the screen only redraws 33.33 times per second, fast-forwarding
or not. This means fast-forward is much more likely to go at the
same speed, no matter what you are looking at.

5bfa014505 Codechange: track _realtime_tick more accurate 
_realtime_tick was reset every time the diff was calculated. This
means if it would trigger, say, every N.9 milliseconds, it would
after two iterations already drift a millisecond. This adds up
pretty quick.

25f6851ca1 Codechange: switch all video drivers to std::chrono for keeping time 
On all OSes we tested the std::chrono::steady_clock is of a high
enough resolution to do millisecond measurements, which is all we
need.

By accident, this fixes a Win32 driver bug, where we would never
hit our targets, as the resolution of the clock was too low to
do accurate millisecond measurements with (it was ~16ms resolution
instead).

f175e38666 Add: [Win32] Automatic zoom level suggestion for Win32 video driver. 
The zoom level suggestion is based on the DPI scaling set in Windows.
We use 150% scaling as the threshold for 2X zoom and 300% scaling
as the threshold for 4X zoom.

1eceee915e Codechange: [SDL2/Win32] Be consistent how 0bpp blitters are not allowed 
Sometimes it returned an usererror(), sometimes Start() failed.
Now it always fails on Start(), so nothing else has to check again
what blitter is used.

AfterBlitterChange() can never change to a 0bpp, so it is sufficient
to guard this with an assert().
