* 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.
* Build the app with -tags="shareware" to compile the free/shareware
build of the game.
* `make build-free` compiles both binaries to the bin/ folder in
shareware mode.
* The constant balance.FreeVersion is true in the shareware build and
all functionality related to the Doodad Editor UI mode is disabled
in this build mode.
* Added Windows build instructions to Building.md and added a
"make mingw" command to cross-compile the Windows binary into
the bin/ folder.
* Fix a bug in the Wallpaper texture loader where it would error out
when caching textures to disk the first time.
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.
* 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.
