Romain Vimont 0538e9645b Improve error handling in screen initialization
After the struct screen is initialized, the window, the renderer and the
texture are necessarily valid, so there is no need to check in
screen_destroy().

Romain Vimont 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.

Romain Vimont f6320c7e31 Wrap SDL thread functions into scrcpy-specific API
The goal is to expose a consistent API for system tools, and paves the
way to make the "core" independant of SDL in the future.

Romain Vimont 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.

Romain Vimont 0ba74fbd9a Make scrcpy.h independant of other headers
The header scrcpy.h is intended to be the "public" API. It should not
depend on other internal headers.

Therefore, declare all required structs in this header and adapt
internal code.

Romain Vimont 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.

Trilinear filtering can currently only be enabled for OpenGL renderers.

Romain Vimont f5aeecbc62 Reset window size on initialization
On macOS with renderer "metal", HiDPI scaling may be incorrect on
initialization when several displays are connected.

Resetting the window size fixes the problem.

Romain Vimont 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).

Romain Vimont 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.

Romain Vimont 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.

Romain Vimont 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.

Romain Vimont 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.
