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.

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.

35a89e5dbe WASM: Store User Files in localStorage
* In WASM build, user levels and doodads are written to localStorage
  using their userdir path as keys (".config/levels/test.level")
* LoadFile() and WriteFile() for both Levels and Doodads interact with
  the localStorage for WASM build instead of filesystem for desktop.
* userdir.ListLevels() and ListDoodads() for WASM scan the localStorage
  keys for file names.
* userdir.ResolvePath() now works for WASM (previously was dummied out),
  checks for the file in localStorage.

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)

c7cc40a339 Refactor Render Texture-Cache Interface
Since SDL2 is using in-memory bitmaps the same as Canvas engine, the
function names of the render.Engine interface have been cleaned up:

* NewTexture(filename, image) -> StoreTexture(name, image)
  Create a new cached texture with a given name.
* NewBitmap(filename) -> LoadTexture(name)
  Recall a stored texture with a given name.
* level.Chunk.ToBitmap uses simpler names for the textures instead of
  userdir.CacheFilename file-like paths.

ba6892aa95 WASM Texture Caching
* Refactor texture caching in render.Engine:
  * New interface method: NewTexture(filename string, image.Image)
  * WASM immediately encodes the image to PNG and generates a JavaScript
    `Image()` object to load it with a data URI and keep it in memory.
  * SDL2 saves the bitmap to disk as it did before.
  * WASM: deprecate the sessionStorage for holding image data. Session
    storage methods panic if called. The image data is directly kept in
    Go memory as a js.Value holding an Image().
* Shared Memory workaround: the level.Chunk.ToBitmap() function is where
  chunk textures get cached, but it had no access to the render.Engine
  used in the game. The `pkg/shmem` package holds global pointers to
  common structures like the CurrentRenderEngine as a work-around.
  * Also shmem.Flash() so Doodle can make its d.Flash() function
    globally available, any sub-package can now flash text to the screen
    regardless of source code location.
  * JavaScript API for Doodads now has a global Flash() function
    available.
* WASM: Handle window resize so Doodle can recompute its dimensions
  instead of scaling/shrinking the view.

48fc40ade4 Texture Caching for WASM Canvas Engine
* Add RGBA color blending support in WASM build.
* Initial texture caching API for Canvas renderer engine. The WASM build
  writes the chunk caches as a "data:image/png" base64 URL on the
  browser's sessionStorage, for access to copy into the Canvas.
* Separated the ClickEvent from the MouseEvent (motion) in the WASM
  event queue system, to allow clicking and dragging.
* Added the EscapeKey handler, which will abruptly terminate the WASM
  application, same as it kills the window in the desktop build.
* Optimization fix: I discovered that if the user clicks and holds over
  a single pixel when drawing a level, repeated Set() operations were
  firing meaning multiple cache invalidations. Not noticeable on PC but
  on WebAssembly it crippled the browser. Now if the cursor isn't moving
  it doesn't do anything.

c5c85330de WASM Event Queue
* Refactor the event system in the WASM render engine to serialize the
  async JavaScript events into a channel, so that queued events are read
  off serially in the main loop similar to SDL. This fixes keyboard
  input issues, altho if you type really fast some input keys get lost.

3d3561b8e6 Blueprint Theme Palette
* Fix the EditorUI not showing the correct palette baked into the level
  and only showing the default. This was tricky because the palette UI
  can only be configured at setup time but not updated later.
* Add a new default palette for the Blueprint theme. Blueprint has a
  dark background, so the palette colors should be bright. This palette
  is chosen when you start a map with the blueprint wallpaper.
* Add a background Canvas to the MenuScene. In the "New Level" screen,
  the background canvas will update to show the wallpaper settings
  you've chosen as a preview of the level theme you're about to create.

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.

87416f9740 Link Tool UX
* On the Doodads tab is the Link button to enter the Link Tool.
* Click Link, then click the 1st doodad on the level, then click the 2nd
  doodad to complete the link.
* The actors struct in the Level holds the link IDs for each actor.

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.

81cb3bd617 1st Round of Doodad Sprites + Improve Doodad Tool
* Improve the `doodad convert` command to convert a series of input
  images into multiple Frames of a Doodad:
  `doodad convert frame1.png frame2.png frameN.png output.doodad`
* Add the initial round of dev-asset sprites for the default Doodads:
  * Button, Button-TypeB and Sticky Button
  * Red, Blue, Green and Yellow Locked Doors and Keys
  * Electric Door
  * Trapdoor Down
* Add dev-assets/palette.json that defines our default doodad color
  palette. Eventually the JSON will be used by the `doodad` tool to give
  the layers meaningful names.
