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.

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.
Trilinear filtering can currently only be enabled for OpenGL renderers.
Do not print a warning if the renderer is not OpenGL, as it can confuses
users, while nothing is wrong.
On macOS with renderer "metal", HiDPI scaling may be incorrect on
initialization when several displays are connected.
Resetting the window size fixes the problem.
Refs #15 <https://github.com/Genymobile/scrcpy/issues/15>
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).
Fixes#15 <https://github.com/Genymobile/scrcpy/issues/15>
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.
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.
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.
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.
Move the window-to-frame coordinates conversion from the input manager
to the screen.
This will allow to apply more screen-related transformations without
impacting the input manager.
Add Ctrl+Left and Ctrl+Right shortcuts to rotate the display (the
content of the scrcpy window).
Contrary to --lock-video-orientation, the rotation has no impact on
recording, and can be changed dynamically (and immediately).
Fixes#218 <https://github.com/Genymobile/scrcpy/issues/218>
Now, get_window_size() returns the current window size (fullscreen or
not), while get_windowed_window_size() always returned the windowed size
(the size when fullscreen is disabled).
The SDL video subsystem is not necessary if we don't display the video.
Move the sdl_init_and_configure() function from screen.c to scrcpy.c,
because it is not only related to the screen display.
Limit source code to 80 chars, and declare functions return type and
modifiers on a separate line.
This allows to avoid very long lines, and all function names are
aligned.
(We do this on VLC, and I like it.)
It is very convenient when I play mobile game and watch video at the
same time.
Tested on Linux mint Cinnamon as well as Windows 10.

SDL_CreateTexture() is called both during initialization and on frame
size change.
To avoid inconsistent changes to arguments value, factorize them to a
single function create_texture().
The High DPI support is enabled by default, so that the renderer use the
full definition of High DPI screens.
However, there are still mouse coordinates problems on some MacOS having
High DPI support (but not all), so expose a way to disable it.
