602273aa16 Add ui.Supervisor for Widget Event Handling
The Buttons can now be managed by a ui.Supervisor and be notified when
the mouse enters or leaves their bounding box and handle click events.

Current event handlers supported:
* MouseOver
* MouseOut
* MouseDown
* MouseUp
* Click

Each of those events are only fired when the state of the event has
changed, i.e. the first time the mouse enters the widget MouseOver is
called and then when the mouse leaves later, MouseOut is called.

A completed click event (mouse was released while pressed and hovering
the button) triggers both MouseOut and Click, so the button can pop
itself out and also run the click handler.

41e1838549 Add JS + History to Shell, Add Main Scene
* The shell now supports an "eval" command, or "$" for short.
  * Runs it in an Otto JavaScript VM.
  * Some global variables are available, like `d` is the Doodle object
    itself, `log`, `RGBA()` and `Point()`
* The shell supports paging through input history using the arrow keys.
* Added an initial Main Scene

94c1df050b Add initial User Interface Toolkit
With Labels and Buttons so far.

* Labels are pretty much complete, they wrap a render.Text and have a
  Compute() method that returns their Width and Height when rendered
  onto an SDL Surface.
* Buttons wrap a Label widget and Compute() its size and takes that into
  consideration when rendering itself. Buttons render themselves from
  scratch in a "Windows 95" themed way, with configurable colors, border
  widths and outline.

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.
