Updates to the radial menu, info panel, slow-motion desaturation, and styling.

tl;dr: Last week I made a lot of improvements to the UX and playability of Meteor Power.

What happened last week?

Highlights

Disable camera-panning when the radial-menu is open.
Fix an issue with radial-menu-item radius sometimes flickering during on-hover transition.
Fix radial-menu center-area radius.
Fix radial-menu-item hover-out transition.
Refactor some radial menu logic live in radial-menu-items rather than the radial-menu.
Create a new SpriteModulationRadialMenuItem.
Add support for sliding the radial-menu and camera when the radial-menu would otherwise render outside the viewport.
Add the station radial menu.
Add a label for the currently-hovered radial-menu item.
Add support for overriding the radial-menu label with a custom scene.
Add an energy cost to the radial-menu label.

A new radial-menu label,
and slow-motion desaturation.

Fix bot lights to not illuminate the bot and nearby parallax background layers.
Update SpriteModulationButton to use ColorConfigs.
Refactor some color-highlight configuration.
Update colors.
Add support for desaturating nodes during slow-motion even if they use materials with custom shaders.
Add support for slow-motion-desaturating color-modulation-based nodes.
Make stations desaturatable.
Make bot and station outlines desaturatable.
Make backgrounds and tilemaps slow-motion-desaturatable.
Make SpriteModulationButtons desaturatable.
Make meteors desaturatable.
Fix navigation-path-preselection annotation to also show a pulse for the invalid-destination indicator.
Fade-out the HUD when a character is active for player control.
Add support for dynamically fading the entire HUD and regions of the HUD.
Update stations to only ever show run-wire as a persistent overlay-button.
Update button image sizes to not include a one-pixel margin.
Fix overlay-button touch screen-radius values.
Add some new button icons.
Update about-screen layout.
Hide all overlay-button-panels when fading hud during nav selection, and when radial-menu is open.
Configure an offset for where to render the radial-panel; nudge this up a bit for stations.
Adjust the styling for the radial-menu-label.
Create an EnergyLabel scene for showing energy costs.
Create an energy icon.

Enable slow-motion when the radial-menu is open.
Add support for enabling slow-motion on any AnimationPlayers and AnimatedSprites.
Enable slow-motion for meteors and stations.
Update display-time values to use a configurable time-type (i.e., slow-motion vs unscaled time).
Fix meteor-power configurations for slow-motion:

Add support for deselecting other bots and stations when selecting a new bot.
Deselect bots and stations when closing the info panel.
Did some experimenting to learn exactly how the sequencing of Godot’s `call_deferred` works:

All `call_deferred` invocations are handled in the same frame they are registered.
Even if a `call_deferred` is registered from the callback of a previous `call_deferred`, it is still handled within that same frame.
The latest `call_deferred` callback is registered at the end of the queue.
This is important information to inform how I’ll add support for listening for _unhandled_ touch events.

Add support for tracking whether a touch-event is unhandled.
Update navigation-path-selection to ignore touch-up events that have already been handled.
Remove LevelControl.is_touch_disabled in favor of LevelControl.mouse_filter == Control.MOUSE_FILTER_IGNORE.
Disambiguate bot-select taps from bot-navigation taps.
Fix issues with radial-menu closing, info-panel closing, and handled-touch-event tracking.
Fix an issue with LevelControl level-space position calculations when they were in the HUD canvas layer.
Update stations and bots to not swallow touch-up events.
Rename player-pointer-listener to player-touch-listener.
Fix navigation-preselection to start on touch-down.
Add support for disabling all level-control touches.
Disable all level-control touches while the player is selecting a navigation path for a character.
Update PauseButton and InspectorPanel-footer to be LevelControls.
Add support for configuring whether to cancel active-character-for-player-nav selection when selecting an invalid nav destination.
Deselect the active bot when selecting an invalid nav destination.
Fix pressed/down event-handler for overlay buttons.

Add support for querying the current progress of a tween.
Update the camera system to support matching a previous camera's offset and zoom.
Reduce camera updates by combining tween-interpolated methods.
Add support for an additional zoom-out/in for different cameras.
Fix camera extra-zoom to not exceed max-zoom.
Fix navigation-preselection to not override zoom.

Fix a strange issue with Godot Dictionaries failing to erase a null (or probably actually a freed object) key.
Add a new home icon.
Fix corner-match-tilemap inner-tilemaps to share the same collision and light layer properties as their parent.
Fix an issue with pausing music when the pause-screen opens.
Update SpriteModulationButton to automatically calculate the sprite scale based on the button size.
Add support for ensuring that a character ends up landing on a surface when stopping an in-progress navigation.
Exit first-wire-end-pressed mode by tapping again on the first-connection station.

New content in the info panel.

Some more info panel improvements.
Add logic for disabling commands when they don't make sense or their isn't enough energy.
Add a simple descriptive tutorial / hints panel.
Some small camera polish.
Refactor the power-line system.

🎉 Cheers!
