To highlight the debug/release mode of the running application, use a
different window icon color in debug mode.

Expose commands to build the application in debug mode.

We encounter some problems with SDL2_image on MSYS2 (Windows), so
implement our own XPM parsing which does not depend on SDL_image.

The input XPM is considered safe (it's in our source repo), so do not
check XPM format errors. This implies that read_xpm() is not safe to
call on any unsafe input.

Although less straightforward, use SDL_CreateRGBSurfaceFrom() instead of
SDL_CreateRGBSurfaceWithFormatFrom() because it is available with SDL
versions older than 2.0.5.

In MSYS2 on Windows, the behavior is the same as on Linux.

On systems where the behavior is not the same, just customize the GRADLE
variable:

    GRADLE=gradlew make release

This reverts commit de192cab.

The hint SDL_HINT_MOUSE_FOCUS_CLICKTHROUGH appeared in SDL 2.0.5. Ignore
it if the SDL version is older.

The default value of GRADLE is "./gradlew", which is the correct value
on Linux.

On Windows, it should use gradlew.bat (by calling "gradlew") instead.

Add a bugdroid icon loaded from an XPM.

The scrcpy() function returns a SDL_bool to indicate its success, but
was initialized to 0 (SDL_FALSE) instead of SDL_TRUE.

To run the app during development, add a recipe "run" to the Makefile.

Expose useful methods directly in Device, without exposing the service
managers.

To guarantee that we instantiate services only one, cache the value the
first time.

The purpose of handle_shortcut() was to group all actions together,
whether they are initiated from a text input event or a keycode event.

However, it did not handle the case where it was initiated from a mouse
event (a right-click must turn the screen on), since the action was
identified by the shortcut char.

Instead, expose one function per action, to be called directly from
where the event is handled.

Document the new shortcuts in the help (scrcpy --help).

When starting scrcpy, immediately turn the screen on.

The right-click is almost useless on Android, so use it to turn the
screen on.

Add a new control event type (command) to request the server to turn the
screen on.

Reformated by Android Studio.

Shortcuts are sometimes initiated from a keycode event, and sometimes
from a text input event.

Move the handling to a unique function.

To simplify event handling code, move all actions to separate functions.

Logs were printed by the caller of switch_fullscreen(). Move them inside
the function to simplify event handling code.

Add shortcuts for HOME, BACK, APPS, POWER, VOLUME_UP and VOLUME_DOWN.

The server is built as an APK to simplify the build, but in fact this is
a simple jar (it is not even signed).

In order to avoid confusion, rename it to .jar, so that users do not try
to "adb install" it.

Also rename it from "scrcpy" to "scrcpy-server" to distinguish from the
client-side.

The server path may be customized using SCRCPY_APK. If its basename is
different from "scrcpy.apk", it will be pushed with a different name,
so the execution would fail.

Therefore, force the push target filename.

Moving the mouse without any button pressed has no effect on Android.
Therefore, do not even send these very frequent events.

Consider a click to gain focus as a click on the device.

Add a command-line option (-b/--bit-rate) to customize the video
bit-rate.

There is no need to call strtol() if the input string is empty.

Trailing new line is not necessary in SDL_Log* methods.

Add a debug log for every succeeded shortcut action.

On rotation, scrcpy resize the window to match the new rotation.
However, in fullscreen mode, setting the window size does not change the
windowed size on X11, so the behavior is incorrect.

To avoid the problem, apply the resize only after fullscreen is
disabled.

Provide command-line help, with -h/--help option.

The long option is --max-size, so for consistency, adapt the code
accordingly.

In addition to the short form (e.g. "-p"), add the long form ("--port").

For readability, indent "case" in switch blocks.

Replace:

    switch (x) {
    case 1:
        // ...
    case 2:
        // ...
    case 3: { // a local scope block
        int i = 42;
        // ...
    }
    }

By:

    switch (x) {
        case 1:
            // ...
        case 2:
            // ...
        case 3: { // a local scope block
            int i = 42;
            // ...
        }
    }

Use the ADB environment variable to provide a custom adb path.

Replace screenrecord execution by manual screen encoding using the
MediaCodec API.

The "screenrecord" solution had several drawbacks:
 - screenrecord output is buffered, so tiny frames may not be accessible
   immediately;
 - it did not output a frame until the surface changed, leading to a
   black screen on start;
 - it is limited to 3 minutes recording, so it needed to be restarted;
 - screenrecord added black borders in the video when the requested
   dimensions did not preserve aspect-ratio exactly (sometimes
   unavoidable since video dimensions must be multiple of 8);
 - rotation handling was hacky (killing the process and starting a new
   one).

Handling the encoding manually allows to solve all these problems.

Never miss an exception by using an uncaught exception handler.

Move argument parsing to a separate method.

Replace our custom Point class by android.graphics.Point.

To simplify the device server-side build, use gradle to create an APK,
even if we use it as a simple jar, by running its main() method.
