Abstract Drawing Canvas into Reusable Widget The `level.Canvas` is a widget that holds onto its Palette and Grid and has interactions to allow scrolling and editing the grid using the swatches available on the palette. Thus all of the logic in the Editor Mode for drawing directly onto the root SDL surface are now handled inside a level.Canvas instance. The `level.Canvas` widget has the following properties: * Like any widget it has an X,Y position and a width/height. * It has a Scroll position to control which slice of its drawing will be visible inside its bounding box. * It supports levels having negative coordinates for their pixels. It doesn't care. The default Scroll position is (0,0) at the top left corner of the widget but you can scroll into the negatives and see the negative pixels. * Keyboard keys will scroll the viewport inside the canvas. * The canvas draws only the pixels that are visible inside its bounding box. This feature will eventually pave the way toward: * Doodads being dropped on top of your map, each Doodad being its own Canvas widget. * Using drawings as button icons for the user interface, as the Canvas is a normal widget.

// TODO: build flags to not include this in production builds.
// This adds accessors for private variables from the dev console.
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.

Move Editor Canvas Into UI + UI Improvements * Increase the default window size from 800x600 to 1024x768. * Move the drawing canvas in EditorMode to inside the EditorUI where it can be better managed with the other widgets it shares the screen with. * Slightly fix Frame packing bug (with East orientation) that was causing right-aligned statusbar items to be partially cropped off-screen. Moved a couple statusbar labels in EditorMode to the right. * Add `Parent()` and `Adopt()` methods to widgets for when they're managed by containers like the Frame. * Add utility functions to UI toolkit for computing a widget's Absolute Position and Absolute Rect, by crawling all parent widgets and summing them up. * Add `lib/debugging` package with useful stack tracing utilities. * Add `make guitest` to launch the program into the GUI Test. The command line flag is: `doodle -guitest` * Console: add a `close` command which returns to the MainScene. * Initialize the font cache directory (~/.cache/doodle/fonts) but don't extract the fonts there yet.
