0044b72943 Drag Doodads Onto Levels in Edit Mode
Add the ability to drag and drop Doodads onto the level. The Doodad
buttons on the palette now trigger a Drag/Drop behavior when clicked,
and a "blueprint colored" version of the Doodad follows your cursor,
centered on it.

Actors are assigned a random UUID ID when they are placed into a level.

The Canvas gained a MaskColor property that forces all pixels in the
drawing to render as the same color. This is a visual-only effect, and
is used when dragging Doodads in so they render as "blueprints" instead
of their actual colors until they are dropped.

Fix the chunk bitmap cache system so it saves in the $XDG_CACHE_FOLDER
instead of /tmp and has better names. They go into
`~/.config/doodle/chunks/` and have UUID file names -- but they
disappear quickly! As soon as they are cached into SDL2 they are removed
from disk.

Other changes:

- UI: Add Hovering() method that returns the widgets that are beneath
      a point (your cursor) and those that are not, for easy querying
      for event propagation.
- UI: Add ability to return an ErrStopPropagation to tell the master
      Scene (outside the UI) not to continue sending events to other
      parts of the code, so that you don't draw pixels during a drag
      event.

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.

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?"

0efb2ab24f Make Collision Detection Flawless!

d560670b7b Better Collision Detection (Bouncy Jumps Up Hills)
* Add a debug view that draws the player bounding boxes.
* Improve the collision detection to add support for:
  * Doodads being "Grounded" so gravity need not apply.
  * Walking up hills, albeit a bit "bouncily"
  * Harder to clip out of bounds

c3fd2e63cb Refactor grid to use level.Pixel and clean up collision between Edit and Play 2018-07-24 17:44:32 -07:00
e141203c4b Basic Collision Detection, Toggle Between Play/Edit
Known bugs:
* The Pixel format in the Grid has DX and DY attributes and
  it wreaks havoc on collision detection in Play Mode when you
  come straight from the editor. Reloading the map from disk to
  play is OK cuz it lacks these attrs.
