bca848d534 Wallpapers and Bounded Levels
Implement the Wallpaper system into the levels and the concept of
Bounded and Unbounded levels.

The first wallpaper image is notepad.png which looks like standard ruled
notebook paper. On bounded levels, the top/left edges of the page look
as you would expect and the blue lines tile indefinitely in the positive
directions. On unbounded levels, you only get the repeating blue lines
but not the edge pieces.

A wallpaper is just a rectangular image file. The image is divided into
four equal quadrants to be the Corner, Top, Left and Repeat textures for
the wallpaper. The Repeat texture is ALWAYS used and fills all the empty
space behind the drawing. (Doodads draw with blank canvases as before
because only levels have wallpapers!)

Levels have four options of a "Page Type":
- Unbounded       (default, infinite space)
- NoNegativeSpace (has a top left edge but can grow infinitely)
- Bounded         (has a top left edge and bounded size)
- Bordered        (bounded with bordered texture; NOT IMPLEMENTED!)

The scrollable viewport of a Canvas will respect the wallpaper and page
type settings of a Level loaded into it. That is, if the level has a top
left edge (not Unbounded) you can NOT scroll to see negative coordinates
below (0,0) -- and if the level has a max dimension set, you can't
scroll to see pixels outside those dimensions.

The Canvas property NoLimitScroll=true will override the scroll locking
and let you see outside the bounds, for debugging.

- Default map settings for New Level are now:
  - Page Type: NoNegativeSpace
  - Wallpaper: notepad.png (default)
  - MaxWidth: 2550  (8.5" * 300 ppi)
  - MaxHeight: 3300 ( 11" * 300 ppi)

20771fbe13 Draw Actors Embedded in Levels in Edit Mode
Add the JSON format for embedding Actors (Doodad instances) inside of a
Level. I made a test map that manually inserted a couple of actors.

Actors are given to the Canvas responsible for the Level via the
function `InstallActors()`. So it means you'll call LoadLevel and then
InstallActors to hook everything up.

The Canvas creates sub-Canvas widgets from each Actor.

After drawing the main level geometry from the Canvas.Chunker, it calls
the drawActors() function which does the same but for Actors.

Levels keep a global map of all Actors that exist. For any Actors that
are visible within the Viewport, their sub-Canvas widgets are presented
appropriately on top of the parent Canvas. In case their sub-Canvas
overlaps the parent's boundaries, their sub-Canvas is resized and moved
appropriately.

- Allow the MainWindow to be resized at run time, and the UI
  recalculates its sizing and position.
- Made the in-game Shell properties editable via environment variables.
  The kirsle.env file sets a blue and pink color scheme.
- Begin the ground work for Levels and Doodads to embed files inside
  their data via the level.FileSystem type.
- UI: Labels can now contain line break characters. It will
  appropriately render multiple lines of render.Text and take into
  account the proper BoxSize to contain them all.
- Add environment variable DOODLE_DEBUG_ALL=true that will turn on ALL
  debug overlay and visualization options.
- Add debug overlay to "tag" each Canvas widget with some of its
  details, like its Name and World Position. Can be enabled with the
  environment variable DEBUG_CANVAS_LABEL=true
- Improved the FPS debug overlay to show in labeled columns and multiple
  colors, with easy ability to add new data points to it.

5bf7d554f7 Add doodad.exe binary and PNG to Drawing Converter
Adds the `doodad` binary which will be a command line tool to work with
Doodads and Levels and assist with development.

The `doodad` binary has subcommands like git and the first command is
`convert` which converts between image files (PNG or BMP) and Doodle
drawing files (Level or Doodad). You can "screenshot" a level into a PNG
or you can initialize a new drawing from a PNG.

a7fd3aa1ca Doodad Edit Mode: Saving and Loading From Disk
Adds the first features to Edit Mode to support creation of Doodad
files! The "New Doodad" button pops up a prompt for a Doodad size
(default 100px) and configures the Canvas widget and makes a Doodad
struct instead of a Level to manage.

* Move the custom Canvas widget from `level.Canvas` to `uix.Canvas`
  (the uix package is for our custom UI widgets now)
* Rename the `doodads.Doodad` interface (for runtime instances of
  Doodads) to `doodads.Actor` and make `doodads.Doodad` describe the
  file format and JSON schema instead.
* Rename the `EditLevel()` method to `EditDrawing()` and it inspects the
  file extension to know whether to launch the Edit Mode for a Level or
  for a Doodad drawing.
* Doodads can be edited by using the `-edit` CLI flag or using the
  in-game file open features (including `edit` command of dev console).
* Add a `Scrollable` boolean to uix.Canvas to restrict the keyboard
  being able to scroll the level, for editing Doodads which have a fixed
  size.

e25869644c Fix Play Mode, Level Handover & Collision Detection
* Edit Mode now uses the Level object itself to keep the drawing data
  rather than pull its Palette and Chunks out, so it can hang on to more
  information. The Canvas widget is given references to the
  Level.Palette and Level.Chunker via Canvas.LoadLevel()
* Fix the handoff between Edit Mode and Play Mode. They pass the Level
  object back and forth and the Filename, because it's not part of the
  Level. You can save the map with its original settings after returning
  from Play Mode.
* Fix the collision detection in Play Mode. It broke previously when
  palettes were added because of the difference between a render.Point
  and a level.Pixel and it couldn't easily look up coordinates. The new
  Chunker system provides a render.Point lookup API.
* All pixels are solid for collision right now, TODO is to return Swatch
  information from the pixels touching the player character and react
  accordingly (non-solid, fire flag, etc.)
* Remove the level.Grid type as it has been replaced by the Chunker.
* Clean up some unused variables and functions.

3c185528f9 Implement Chunk System for Pixel Data
Starts the implementation of the chunk-based pixel storage system for
levels and drawings.

Previously the levels had a Pixels structure which was just an array of
X,Y and palette index triplets. The new chunk system divides the map up
into square chunks, and lets each chunk manage its own memory layout.

The "MapAccessor" layout is implemented first which is a map of X,Y
coordinates to their Swatches (pointer to an index of the palette). When
serialized the MapAccessor maps the "X,Y": "index" similarly to the old
Pixels array.

The object hierarchy for the chunk system is like:

* Chunker: the manager of the chunks who keeps track of the ChunkSize
  and a map of "chunk coordinates" to the chunk in charge of it.
  * Chunk: a part of the drawing ChunkSize length square. A chunk has a
    Type (of how it stores its data, 0 being a map[Point]Swatch and 1
    being a [][]Swatch 2D array), and the chunk has an Accessor which
    implements the underlying type.
    * Accessor: an interface for a Chunk to provide access to its
      pixels.
      * MapAccessor: a "sparse map" of coordinates to their Swatches.
      * GridAccessor: TBD, will be a "dense" 2D grid of Swatches.

The JSON files are loaded in two passes:

1. The chunks only load their swatch indexes from disk.
2. With the palette also loaded, the chunks are "inflated" and linked
   to their swatch pointers.

Misc changes:

* The `level.Canvas` UI widget switches from the old Grid data type to
  being able to directly use a `level.Chunker`
* The Chunker is a shared data type between the on-disk level format and
  the actual renderer (level.Canvas), so saving the level is easy
  because you can just pull the Chunker out from the canvas.
* ChunkSize is stored inside the level file and the default value is at
  balance/numbers.go: 1000

5956863996 Menu Toolbar for Editor + Shell Prompts + Theme
* Added a "menu toolbar" to the top of the Edit Mode with useful buttons
  that work: New Level, New Doodad (same thing), Save, Save as, Open.
* Added ability for the dev console to prompt the user for a question,
  which opens the console automatically. "Save", "Save as" and "Load"
  ask for their filenames this way.
* Started groundwork for theming the app. The palette window is a light
  brown with an orange title bar, the Menu Toolbar has a black
  background, etc.
* Added support for multiple fonts instead of just monospace. DejaVu
  Sans (normal and bold) are used now for most labels and window titles,
  respectively. The dev console uses DejaVu Sans Mono as before.
* Update ui.Label to accept PadX and PadY separately instead of only
  having the Padding option which did both.
* Improvements to Frame packing algorithm.
* Set the SDL draw mode to BLEND so we can use alpha colors properly,
  so now the dev console is semi-translucent.

e1cbff8c3f Add Palette Window and Palette Support to Edit Mode
* Add ui.Window to easily create reusable windows with titles.
* Add a palette window (panel) to the right edge of the Edit Mode.
  * Has Radio Buttons listing the colors available in the palette.
* Add palette support to Edit Mode so when you draw pixels, they take
  on the color and attributes of the currently selected Swatch in your
  palette.
* Revise the on-disk format to better serialize the Palette object to
  JSON.
* Break Play Mode: collision detection fails because the Grid key
  elements are now full Pixel objects (which retain their Palette and
  Swatch properties).
  * The Grid will need to be re-worked to separate X,Y coordinates from
    the Pixel metadata to just test "is something there, and what is
    it?"

27fafdc96d Save and restore maps as JSON files
First pass at a level storage format to save and restore maps.

To save a map: press F12. It takes a screenshot PNG into the
screenshots/ folder and outputs a map JSON in the working directory.

To restore a map: "go run cmd/doodle/main.go map.json"
