626fd53a84 Checkpoint Flag can Re-assign Player Character
Link a Doodad to a Checkpoint Flag (like you would a Start Flag) and
crossing the flag will replace the player with that doodad. Multiple
checkpoint flags like this can toggle you between characters.

* Azulians are now friendly to player characters who have the word
  "Azulian" in their title.
* Improve Bird as the playable character:
  * Dive animation if the player flies diagonally downwards
  * Animation loop while hovering in the air instead of pausing
* Checkpoint flags don't spam each other on PubSub so much which could
  sometimes lead to deadlocks!

SetPlayerCharacter added to the JavaScript API. The Checkpoint Flag
(not the region) can link to a doodad and replace the player character
with that linked doodad when you activate the checkpoint:

    Actors.SetPlayerCharacter(filename string): like "boy.doodad"

Add various panic catchers to make JavaScript safer and log issues
to console.

4d08bf1d85 Switch JavaScript engine to goja
* Switch from otto to goja for JavaScript engine.
* goja supports many ES6 syntax features like arrow functions,
  const/let, for-of with more coming soon.
* Same great features as otto, more modern environment for doodads!

0fa1bf8a76 Editor: Doodad Properties Window
The Doodad Properties window brings many features that used to be
available only in the `doodad` CLI tool into the Doodad Editor.

* In the Doodad Editor there is a new menubar item: "Doodad" which
  corresponds to the "Level" menu when you're editing a level.
* The "Doodad" menu has two items:
  - "Doodad Properties" (NEW)
  - "Layers" (moved here from the Tools menu)
* The Doodad Properties window lets you edit the Title and Author values
  of the doodad, as well as modify its Tags and manage its Script.
* Its script can be attached (browse for .js file on disk), its existing
  script saved back to disk (dev shell prompt) or deleted altogether
  from the doodad.
* You can create, modify, and delete Tags on the doodad.

Other changes:

* In the Level Editor, the "Level->Page Settings" menu is renamed to
  "Level->Level Properties" to match with "Doodad->Doodad Properties"
  and the pop-up window is retitled accordingly.
* The Exit Flag only exits if the Player touches it - not just any
  mobile doodad!

1ac85c9297 Checkpoint Flag & Retry from Checkpoint
* New Doodad: Checkpoint Flag. They update the player's spawn point
  whenever the player passes one. The most recently activated
  checkpoint is rendered brighter than the others.
* End Level Modal: the fake alert box window drawn by the Play Mode
  is replaced with a fancy modal widget (similar to Alert and Confirm).
  It handles level victory or failure conditions and can show or hide
  all the buttons as needed.
* Gameplay: There is a "Retry from Checkpoint" option added, which
  appears in the level failure modal. It will teleport you back to
  the Start Flag or the last Checkpoint Flag you had touched, without
  resetting the level -- your keys, unlocked doors, etc. will be
  preserved so you can retry.
* Set a maximum speed on the "Camera Follows Actor" logic of 64
  pixels per tick. This results in a smoother scrolling transition
  when the player jumps to a new location on the map, such as by
  a Warp Door.
* Update the default color palettes:
    * All: Add a "hint" magenta color.
    * Colored Pencil: Add a "darkstone" solid color.

Updates to the Doodads JavaScript API:

* SetCheckpoint(Point(x, y)): set the player character's spawn
  position. Giving it Self.Position() is an easy way to set the
  player spawn to your doodad's location.

405aaf509d Link Start Flags to Change Characters
New feature: link a Start Flag to another doodad in your level
and you will play as that doodad instead of Boy. All Creatures
are designed to be playable. Playing as "other" doodads leads
to interesting effects, like not being able to activate buttons,
switches, or warp doors and not having an inventory to pick up
keys. The Anvil is fun: it can destroy other mobile doodads by
jumping on them.

If the actor does not specify that it has gravity, the gameplay
starts in antigravity mode. This will be the vast majority of
non-mobile doodads and the Bird.

Other changes:

* The Blue and Red Azulians now share a doodad script.
* The Azulians AI is still to walk back and forth, pickup keys and
  press buttons. The Blue Azulian walks slower than the red one.
* The Blue Azulian is no longer hidden from the doodads list.
* Actor UUID values in levels are now V1 UUIDs (time-ordered).
  This will help to reliably resolve conflicts in draw order
  of overlapping doodads (newest added to level wins).
* Link Tool: clicking on a pair of already-linked doodads will
  now unlink them, so you don't have to delete one to delete
  the link.
* Actor Tool: deleting an actor immediately calls PruneLinks()
  to clean up any links that the deleted doodad might have.

0518df226c New Doodad: Anvil
* The Anvil doodad is affected by gravity and becomes dangerous when
  falling. If it lands on the player character, you die! If it lands on
  any other mobile doodad, it destroys it! It can land on solid doodads
  such as the Electric Trapdoor and the Crumbly Floor. It will activate
  a Crumbly Floor if it lands on one, and can activate buttons and
  switches that it passes.
* JavaScript API: FailLevel(message) can be called from a doodad to kill
  the player character. The Anvil does this if it collides with the
  player while it's been falling.

810ba193d9 Doodads: Electric Trapdoor and Resettable Box
* New doodad: Electric Trapdoor. It is a horizontal version of the
  Electric Door. Opens while powered by a button or a switch and closes
  when it loses power.
* The Box doodad will reset to its original location if it receives a
  power signal from a linked Button or Switch. So for box pushing
  puzzles you can add a reset button in case the boxes get stuck.
* Refactored the Doodad build scripts into many Makefiles for easier
  iteration (don't need to compile ALL doodads to test one).

Updates to the JavaScript API for doodads:

* Self.MoveTo(Point) is now available to set the actor's position in
  world coordinates.

3892087932 Doodads: Use Key and Working Warp Doors
* The "Use Key" (Q or Spacebar) now activates the Warp Door instead of a
  collision event doing so.
* Warp Doors are now functional: the player opens a door, disappears,
  the door closes; player is teleported to the linked door which opens,
  appears the player and closes.
* If the player exits thru a Blue or Orange door which is disabled
  (dotted outline), the door still opens and drops the player off but
  returns to a Disabled state, acting as a one-way door.
* Clean up several debug log lines from Doodle and doodad scripts.

38614ee280 Tighten Doodad JavaScript API, User Documentation
* Tightens up the surface area of API methods available to the
  JavaScript VMs for doodads. Variables and functions are carefully
  passed in one-by-one so the doodad script can only access intended
  functions and not snoop on undocumented APIs.
* Wrote tons of user documentation for Doodad Scripts: documented the
  full surface area of the exposed JavaScript API now that the surface
  area is known and limited.
* Early WIP code for the Campaign JSON

08e65c32b5 Overhaul the Platformer Physics System
* Player character now experiences acceleration and friction when
  walking around the map!
* Actor position and movement had to be converted from int's
  (render.Point) to float64's to support fine-grained acceleration
  steps.
* Added "physics" package and physics.Vector to be a float64 counterpart
  for render.Point. Vector is used for uix.Actor.Position() for the sake
  of movement math. Vector is flattened back to a render.Point for
  collision purposes, since the levels and hitboxes are pixel-bound.
* Refactor the uix.Actor to no longer extend the doodads.Drawing (so it
  can have a Position that's a Vector instead of a Point). This broke
  some code that expected `.Doodad` to directly reference the
  Drawing.Doodad: now you had to refer to it as `a.Drawing.Doodad` which
  was ugly. Added convenience method .Doodad() for a shortcut.
* Moved functions like GetBoundingRect() from doodads package to
  collision, where it uses its own slimmer Actor interface for just the
  relevant methods it needs.

8965a7d86a Doodads: Crumbly Floor, Start Flag & State Blocks
Add new doodads:

* Start Flag: place this in a level to set the spawn point of the player
  character. If no flag is found, the player spawns at 0,0 in the top
  corner of the map. Only use one Start Flag per level, otherwise the
  player will randomly spawn at one of them.
* Crumbly Floor: a solid floor that begins to shake and then fall apart
  after a moment when a mobile character steps on it. The floor respawns
  after 5 seconds.
* State Blocks: blue and orange blocks that toggle between solid and
  pass-thru whenever a State Button is activated.
* State Button: a solid "ON/OFF" block that toggles State Blocks back
  and forth when touched. Only activates if touched on the side or bottom;
  acts as a solid floor when walked on from the top.

New features for doodad scripts:

* Actor scripts: call SetMobile(true) to mark an actor as a mobile mob
  (i.e. player character or enemy). Other doodads can check if the actor
  colliding with them IsMobile so they don't activate if placed too close
  to other (non-mobile) doodads in a level. The Blue and Red Azulians
  are the only mobile characters so far.
* Message.Broadcast allows sending a pub/sub message out to ALL doodads
  in the level, instead of only to linked doodads as Message.Publish does.
  This is used for the State Blocks to globally communicate on/off status
  without needing to link them all together manually.

65a811db0d Auto-prune Empty Chunks in Level Files
* Discovered a bug where if you hit the Undo key to erase pixels and an
  entire chunk became empty by it, the chunk would have rendering errors
  and show as a solid black square instead of the level wallpaper
  showing through.
* Chunks that have no pixels in them are culled from the chunker
  immediately when you call a Delete() operation.
* The level file saver also calls a maintenance function to prune all
  empty chunks upon saving the file. So existing levels with broken
  chunks need only be re-saved to fix them.

0c22ecae5e Level Exit Doodad
* Add a Level Exit doodad, which for now is a little blue flag on a pole
  that reads "END"
* JavaScript API: global function EndLevel() will end the level. The
  exit doodad calls this when touched by the player.
* Add a "Level Completed" alert box UI to PlayScene with dynamic button
  layouts.
  * The alert box pops up when a doodad calls EndLevel() and contains
    action buttons what to do next.
  * "Play Again" restarts the current level again.
  * "Edit Level" if you came from the EditorScene; otherwise this button
    is not visible.
  * "Next Level" is a to-be-implemented button to advance in the single
    player story mode. Only shows up when PlayScene.HasNext=true.
  * "Exit to Menu" is always visible and closes out to the MainScene.
