Use ring example.

Use minimal server echo example instead.

The client app is able to connect to the server, however no further
communication is happening. Must've been the callbacks?

Also the client app enters into an infinite loop when lws_service() is
called inside the game loop.

Set log level to 0 for SDL to handle logging.

Add libwebsockets client to game executable.

Protocol retrieved from lws git repo for samples.

Websockets server is for game networking.

Only check if events should break the game loop instead of having a
separate member for game loop checking.

Delegate the event handling solely in input state.

Add tests for initialization and teardown for all input methods.

Specify describe block for each player tests.

Allow current item pointer to have custom type.

Change the pool list initializations.

Add memory and data-related implementations for handling game data.

Use consistent integer types for mocks.

Properly mock video function dependencies.

Correctly dereference pointers.

Update input tests.

Declare memory before processing.

Declare variables early on.

Use short names for int types.

Provide default states for input and output.

Allow MIDI input to be filtered through MIDI channels.

Use higher bits of first message byte to get notes from all channels.

Restrict Yes/No actions in same 2-octave span.

The file has been updated upon introducing MIDI controller input
support.

The game now uses MIDI support for alternative input methods.

Put I/O values to their respective structs.

Isolate input items into their own directory.

Ensure joystick direction enum names are consistent.

Ensure each initialization method is in its own source.

Ensure correct arguments are passed.

Determine config path only once.

Add spine-runtimes to dependencies

Add geometry methods for point, vector, and rectangle.

Ensure one type of test can only be handled at a time.

Implement tests for joystick axis, hat, and button events.

Order files from order of includes.

Add third-party mocks, specify mock files.

/? Do we need first-party mocks in their own files, or can we provide a
mock flag in the implementation files already?

Make device handling opt-in.

Use types from header file.

Use call count type to contextualize call counts.

Use macros for syntactic sugar.

Include mocks and stubs implementation in config unit tests.

Use #define instead of const for constants.

Use bdd-for-c for unit tests.

Honor the FPS cap with updating video. Now the update occurs after
processing all the input actions.

Implement event handling for gamepads and joysticks.

In addition, the events are ordered according to SDL compatibility.

Extract config-related code to their own source files.

Ensure that initial loading of the config saves the values back to the
config file, in order to account for fallback values.
