7355778a39 render: Refactor Events System to Make Module Standalone
* Refactor the events used in lib/render/sdl to be more general-purpose
  to make librender a stand-alone library separate from Doodle.

154fc6c9cb Update Doodad build-scripts to tag extra data
* The Blue Azulian marks its doodad file as Hidden.
* All Doodads are write locked after generation and tagged with common
  author value.

6476a67faf Make Fire Deadly
* Touching "fire" pixels in a level will pop up the End Level alert box
  saying you've died by fire and can restart the level.
* Update level.WriteFile() to prune broken links between actors before
  save. So when a linked actor is deleted, the leftover link data is
  cleaned up.
* Slight optimization in Canvas.drawStrokes: if either end of the stroke
  is not within view of the screen, don't show the stroke.

cb02feff1d Add Switches, Fire/Water Collision and Play Menu
* New doodads: Switches.
  * They come in four varieties: wall switch (background element, with
    "ON/OFF" text) and three side-profile switches for the floor, left
    or right walls.
  * On collision with the player, they flip their state from "OFF" to
    "ON" or vice versa. If the player walks away and then collides
    again, the switch flips again.
  * Can be used to open/close Electric Doors when turned on/off. Their
    default state is "off"
  * If a switch receives a power signal from another linked switch, it
    sets its own state to match. So, two "on/off" switches that are
    connected to a door AND to each other will both flip on/off when one
    of them flips.
* Update the Level Collision logic to support Decoration, Fire and Water
  pixel collisions.
  * Previously, ALL pixels in the level were acting as though solid.
  * Non-solid pixels don't count for collision detection, but their
    attributes (fire and water) are collected and returned.
* Updated the MenuScene to support loading a map file in Play Mode
  instead of Edit Mode. Updated the title screen menu to add a button
  for playing levels instead of editing them.
* Wrote some documentation.

dc2695cfc9 Add More Trapdoor Doodads
* Add the other trapdoor directions: Left, Right and Up.
* UI: Show a color square in each Palette Swatch button in Edit Mode.
  * Instead of just the label like "solid", "fire", "decoration" it also
    shows a square box colored as the swatch color. The label and box
    are left-aligned in the button.
* Minor Play Mode physics update:
  * The player jump is now limited: they may only continue to move
    upwards for 20 ticks, after which they must touch ground before
    jumping again.
  * Remove the "press Down to move down" button. Only gravity moves you
    down.
* Fix a crash in the Editor Mode when you dragged doodads on top of each
  other. Source of bug was the loopActorCollision() function, which only
  should be useful to Play Mode, and it expected the scripting engine to
  be attached to the Canvas. In EditorMode there is no scripting engine.

c8620f871e Drawing Strokes and Undo/Redo Functionality
* Add new pkg/drawtool with utilities to abstract away drawing actions
  into Strokes and track undo/redo History for them.
* The freehand Pencil tool in EditorMode has been refactored to create a
  Stroke of Shape=Freehand and queue up its world pixels there instead
  of directly modifying the level chunker in real time. When the mouse
  button is released, the freehand Stroke is committed to the level
  chunker and added to the UndoHistory.
* UndoHistory is (temporarily) stored with the level.Level so it can
  survive trips to PlayScene and back, but is not stored as JSON on
  disk.
* Ctrl-Z and Ctrl-Y in EditorMode for undo and redo, respectively.

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.

b17ca34de2 Bindata: Embedding Doodads and Levels (for WASM)
* Use `go-bindata` to embed built-in doodads and levels directly into
  the Doodle binary. `make bindata` produces the bindata source file.
* Add `FromJSON()` method to Levels and Doodads to load objects from
  JSON strings in memory (for bindata built-ins or WASM ajax requests)
* Update file loading functions to check the embedded bindata files.
  * pkg/config.go#EditFile:
    * Supports editing a level from bindata (TODO: remove this support)
    * If the "assets/levels/%(simple-name.level)" exists in bindata,
      edits that drawing.
    * No such support for editing built-in doodads.
    * WASM has no filesystem access to edit files except built-in
      levels (yet)
  * pkg/doodads#ListDoodads:
    * Prepends built-in doodads from bindata to the returned list.
    * WASM: no filesystem access so gets only the built-ins.
  * pkg/doodads#LoadFile:
    * Checks built-in bindata store first for doodad files.
    * WASM: tries an HTTP request if not found in bindata but can go no
      further if not found (no filesystem access)
  * pkg/filesystem#FindFile:
    * This function finds a level/doodad by checking all the places.
    * If the level or doodad exists in bindata built-in, always returns
      its system path like "assets/doodads/test.doodad"
    * WASM: always returns the built-in candidate path even if not found
      in bindata so that ajax GET can be attempted.
  * pkg/level#ListSystemLevels:
    * New function that lists the system level files, similar to the
      equivalent doodads function.
    * Prepends the bindata built-in level files.
    * WASM: only returns the built-ins (no filesystem support)
    * Desktop: also lists and returns the assets/levels/ directory.
  * pkg/level#LoadFile:
    * Like the doodads.LoadFile, tries from built-in bindata first, then
      ajax request (WASM) before accessing the filesystem (desktop)
* Menu Scene: TODO, list the built-in levels in the Load Level menu.
  This feature will soon go away when WASM gets its own storage for user
  levels (localStorage instead of filesystem)

9efe16582c Add Play/Edit Buttons to Toggle Between Modes
* Instead of needing to press the "P" and "E" keys to toggle from edit
  mode to play mode (and back again), respectively, the UI now draws a
  "Play (P)" or "Edit (E)" button on the bottom right corner of the
  level canvas. Clicking it will toggle the mode.

4dd1bebc5f Add MenuScene with New Level UI
* Debug mode: no longer enables the DebugOverlay (F3) by default, but
  does now insert the current FPS counter into the window title bar.
* ui.Frame: set a default "mostly transparent" BG color so the frame
  background doesn't render as white.
* Add the MenuScene which will house the game's main menus.
* The "New Level" menu is first to be added.
  * UI lets you pick Page Type and Wallpaper using radio buttons.
  * Page Type: Unbounded, Bounded (default), No Negative Space, Bordered
  * Fix bugs in uix.Canvas to fully support all these page types.

d28745f89e Mobile Enemy Doodad Test
* Add a Red Azulian as a test for mobile enemies.
  * Its A.I. has it walk back and forth, changing directions when it
    comes up against an obstacle for a few moments.
  * It plays walking animations and can trigger collision events with
    other Doodads, such as the Electric Door and Trapdoor.
* Move Gravity responsibility to the doodad scripts themselves.
  * Call `Self.SetGravity(true)` to opt the Doodad in to gravity.
  * The canvas.Loop() adds gravity to any doodad that has it enabled.

f76ba6fbb7 WIP: MsgPack stubs, Level Filesystem Module
* Add some encoding/decoding functions for binary msgpack format for
  levels and doodads. Currently it writes msgpack files that can be
  decoded and printed by Python (mp2json.py) but it can't re-read from
  the binary format. For now, levels will continue to write in JSON
  format.
* Add filesystem abstraction functions to the balance/ package to search
  multiple paths to find Levels and Doodads, to make way for
  system-level doodads.

258b2eb285 Script Timers, Multiple Doodad Frames
* CLI: fix the `doodad convert` command to share the same Palette when
  converting each frame (layer) of a doodad so subsequent layers find
  the correct color swatches for serialization.
* Scripting: add timers and intervals to Doodad scripts to allow them to
  animate themselves or add delayed callbacks. The timers have the same
  API as a web browser: setTimeout(), setInterval(), clearTimeout(),
  clearInterval().
* Add support for uix.Actor to change its currently rendered layer in
  the level. For example a Button Doodad can set its image to Layer 1
  (pressed) when touched by the player, and Trapdoors can cycle through
  their layers to animate opening and closing.
  * Usage from a Doodad script: Self.ShowLayer(1)
* Default Doodads: added scripts for all Buttons, Doors, Keys and the
  Trapdoor to run their various animations when touched (in the case of
  Keys, destroy themselves when touched, because there is no player
  inventory yet)

1e80304061 Initial Doodad JavaScript System
* Add the JavaScript system for Doodads to run their scripts in levels,
  and wire initial OnCollide() handler support.
* CLI: Add a `doodad install-script` command to the doodad tool.
  * Usage: `doodad install-script <index.js> <filename.doodad>`
* Add dev-assets folder for storing source files for the official
  default doodads, sprites, levels, etc. and for now add a JavaScript
  for the first test doodad.

241186209c Play Mode: Fix Level Collision w/ Scrolling
Fixes:
* Move the call to CollidesWithGrid() inside the Canvas instead of
  outside in the PlayScene.movePlayer() so it can apply to all Actors
  in motion.
* PlayScene.movePlayer() in turn just sets the player's Velocity so the
  Canvas.Loop() can move the actor itself.
* When keeping the player inside the level boundaries: previously it was
  assuming the player Position was relative to the window, and was
  checking the WorldIndexAt and getting wrong results.
* Canvas scrolling (loopFollowActor): check that the actor is getting
  close to the screen edge using the Viewport into the world, NOT the
  screen-relative coordinates of the Canvas bounding boxes.
