cb9c42bdcb Use a callback to notify frame skip
A skipped frame is detected when the producer offers a frame while the
current pending frame has not been consumed.

However, the producer (in practice the decoder) is not interested in the
fact that a frame has been skipped, only the consumer (the renderer) is.

Therefore, notify frame skip via a consumer callback. This allows to
manage the skipped and rendered frames count at the same place, and
remove fps_counter from decoder.

441d3fb119 Make video buffer more generic
Video buffer is a tool between a frame producer and a frame consumer.

For now, it is used between a decoder and a renderer, but in the future
another instance might be used to swscale decoded frames.

c0c4ba7009 Add intermediate frame in video buffer
There were only two frames simultaneously:
 - one used by the decoder;
 - one used by the renderer.

When the decoder finished decoding a frame, it swapped it with the
rendering frame.

Adding a third frame provides several benefits:
 - the decoder do not have to wait for the renderer to release the
   mutex;
 - it simplifies the video_buffer API;
 - it makes the rendering frame valid until the next call to
   video_buffer_take_rendering_frame(), which will be useful for
   swscaling on window resize.

e8a565f9ea Fix touch events HiDPI-scaling
Touch events were HiDPI-scaled twice:
 - once because the position (provided as floats between 0 and 1) were
   converted in pixels using the drawable size (not the window size)
 - once due to screen_convert_to_frame_coords()

One possible fix could be to compute the position in pixels from the
window size instead, but this would unnecessarily round the event
position to the nearest window coordinates (instead of drawable
coordinates).

Instead, expose two separate functions to convert to frame coordinates
from either window or drawable coordinates.

ac4c8b4a3f Increase LOD bias for mipmapping
Mipmapping caused too much blurring.

Using a LOD bias of -1 instead of -0.5 seems a better compromise to
avoid low-quality downscaling while keeping sharp edges in any case.

e40532a376 Manually position and scale the content
Position and scale the content "manually" instead of relying on the
renderer "logical size".

This avoids possible rounding differences between the computed window
size and the content size, causing one row or column of black pixels on
the bottom or on the right.

This also avoids HiDPI scale issues, by computing the scaling manually.

This will also enable to draw items at their expected size on the screen
(unscaled).

ec047b501e Disable "resize to fit" in maximized state
In maximized state (but not fullscreen), it was possible to resize to
fit the device screen (with Ctrl+x or double-clicking on black borders).

This caused problems on macOS with the "expand to fullscreen" feature,
which behaves like a fullscreen mode but is seen as maximized by SDL.
In that state, resizing to fit causes unexpected results.

To keep the behavior consistent on all platforms, just disable "resize
to fit" when the window is maximized.

4c2e10fd74 Workaround maximized+fullscreen on Windows
On Windows, in maximized+fullscreen state, disabling fullscreen mode
unexpectedly triggers the "restored" then "maximized" events, leaving
the window in a weird state (maximized according to the events, but not
maximized visually).

Moreover, apply_pending_resize() asserts that fullscreen is disabled.

To avoid the issue, if fullscreen is set, just ignore the "restored"
event.

6b1da2fcff Simplify size changes in fullscreen or maximized
If the content size changes (due to rotation for example) while the
window is maximized or fullscreen, the resize must be applied once
fullscreen and maximized are disabled.

The previous strategy consisted in storing the windowed size, computing
the target size on rotation, and applying it on window restoration. But
tracking the windowed size (while ignoring the non-windowed size) was
tricky, due to unspecified order of SDL events (e.g. size changes can be
notified before "maximized" events), race conditions when reading window
flags, different behaviors on different platforms...

To simplify the whole resize management, store the old content size (the
frame size, possibly rotated) when it changes while the window is
maximized or fullscreen, so that the new optimal size can be computed on
window restoration.

8581d6850b Stabilize auto-resize
The window dimensions are integers, so resizing to fit the content may
not be exact.

When computing the optimal size, it could cause to reduce alternatively
the width and height by few pixels, making the "optimal size" unstable.

To avoid this problem, check if the optimal size is already correct
either by keeping the width or the height.
