// -----------
// | DATA FLOW |
// -----------
//
// Data flows in a circular motion via channels. This allows each component to handle and
// process data on their own thread while not blocking the other components from processing.
//
// This way Neovim continues to produce events, the window doesn't freeze and queues up ui
// commands, and the editor can do the processing necessary to handle the UI events
// effectively.
//
// BRIDGE
// V REDRAW EVENT
// EDITOR
// V DRAW COMMAND
// WINDOW
// V UI COMMAND
// BRIDGE
//
// BRIDGE:
// The bridge is responsible for the connection to the neovim process itself. It is in charge
// of starting and communicating to and from the process.
//
// REDRAW EVENT:
// Redraw events are direct events from the neovim process meant to specify how the editor
// should be drawn to the screen. They also include other things such as whether the mouse is
// enabled. The bridge takes these events, filters out some of them meant only for
// filtering, and forwards them to the editor.
//
// EDITOR:
// The editor is responsible for processing and transforming redraw events into something
// more readily renderable. Ligature support and multi window management requires some
// significant preprocessing of the redraw events in order to capture what exactly should get
// drawn where. Futher this step takes a bit of processing power to accomplish, so it is done
// on it's own thread. Ideally heavily computationally expensive tasks should be done in the
// editor.
//
// DRAW COMMAND:
// The draw commands are distilled render information describing actions to be done at the
// window by window level.
//
// WINDOW:
// The window is responsible for rendering and gathering input events from the user. This
// inncludes taking the draw commands from the editor and turning them into pixels on the
// screen. The ui commands are then forwarded back to the BRIDGE to convert them into
// commands for neovim to handle properly.
//
// UI COMMAND:
// The ui commands are things like text input/key bindings, outer window resizes, and mouse
// inputs.
//
// ------------------
// | Other Components |
// ------------------
//
// Neovide also includes some other systems which are globally available via lazy static
// instantiations.
//
// SETTINGS:
// The settings system is live updated from global variables in neovim with the prefix
// "neovide". They allow us to configure and manage the functionality of neovide from neovim
// init scripts and variables.
//
// REDRAW SCHEDULER:
// The redraw scheduler is a simple system in charge of deciding if the renderer should draw
// another frame next frame, or if it can safely skip drawing to save battery and cpu power.
// Multiple other parts of the app "queue_next_frame" function to ensure animations continue
// properly or updates to the graphics are pushed to the screen.

// -----------
// | DATA FLOW |
// -----------
//
// Data flows in a circular motion via channels. This allows each component to handle and
// process data on their own thread while not blocking the other components from processing.
//
// This way Neovim continues to produce events, the window doesn't freeze and queues up ui
// commands, and the editor can do the processing necessary to handle the UI events
// effectively.
//
// BRIDGE
// V REDRAW EVENT
// EDITOR
// V DRAW COMMAND
// WINDOW
// V UI COMMAND
// BRIDGE
//
// BRIDGE:
// The bridge is responsible for the connection to the neovim process itself. It is in charge
// of starting and communicating to and from the process.
//
// REDRAW EVENT:
// Redraw events are direct events from the neovim process meant to specify how the editor
// should be drawn to the screen. They also include other things such as whether the mouse is
// enabled. The bridge takes these events, filters out some of them meant only for
// filtering, and forwards them to the editor.
//
// EDITOR:
// The editor is responsible for processing and transforming redraw events into something
// more readily renderable. Ligature support and multi window management requires some
// significant preprocessing of the redraw events in order to capture what exactly should get
// drawn where. Futher this step takes a bit of processing power to accomplish, so it is done
// on it's own thread. Ideally heavily computationally expensive tasks should be done in the
// editor.
//
// DRAW COMMAND:
// The draw commands are distilled render information describing actions to be done at the
// window by window level.
//
// WINDOW:
// The window is responsible for rendering and gathering input events from the user. This
// inncludes taking the draw commands from the editor and turning them into pixels on the
// screen. The ui commands are then forwarded back to the BRIDGE to convert them into
// commands for neovim to handle properly.
//
// UI COMMAND:
// The ui commands are things like text input/key bindings, outer window resizes, and mouse
// inputs.
//
// ------------------
// | Other Components |
// ------------------
//
// Neovide also includes some other systems which are globally available via lazy static
// instantiations.
//
// SETTINGS:
// The settings system is live updated from global variables in neovim with the prefix
// "neovide". They allow us to configure and manage the functionality of neovide from neovim
// init scripts and variables.
//
// REDRAW SCHEDULER:
// The redraw scheduler is a simple system in charge of deciding if the renderer should draw
// another frame next frame, or if it can safely skip drawing to save battery and cpu power.
// Multiple other parts of the app "queue_next_frame" function to ensure animations continue
// properly or updates to the graphics are pushed to the screen.
