ddcad27485 WIP: Chunker size to uint8 and Rectangular Doodads
Convert the Chunker size to a uint8 so chunk sizes are limited to 255px. This
means that inside of a chunk, uint8's can track the relative pixel coordinates
and result in a great memory savings since all of these uint8's are currently
64-bits wide apiece.

WIP on rectangular shaped doodads:
* You can create such a doodad in the editor and draw it normally.
* It doesn't draw the right size when dragged into your level however:
  - In uix.Actor.Size() it gets a rect of the doodad's square Chunker size,
    instead of getting the proper doodad.Size rect.
  - If you give it the doodad.Size rect, it draws the Canvas size correctly
    instead of a square - the full drawing appears and in gameplay its hitbox
    (assuming the same large rectangle size) works correctly in-game.
  - But, the doodad has scrolling issues when it gets to the top or left edge
    of the screen! This old gnarly bug has come back. For some reason square
    canvas doodads draw correctly but rectangular ones have the drawing scroll
    just a bit - how far it scrolls is proportional to how big the doodad is,
    with the Start Flag only scrolling a few pixels before it stops.

fb5a8a1ae8 Async Giant Screenshot, Player Physics and UI Polish
* The "Giant Screenshot" feature takes a very long time, so it is made
  asynchronous. If you try and run a second one while the first is busy,
  you get an error flash. You can continue editing the level, even
  playtest it, or load a different level, and it will continue crunching
  on the Giant Screenshot and flash when it's finished.
* Updated the player physics to use proper Velocity to jump off the
  ground rather than the hacky timer-based fixed speed approach.
* FlashError() function to flash "error level" messages to the screen.
  They appear in orange text instead of the usual blue, and most error
  messages in the game use this now. The dev console "error <msg>"
  command can simulate an error message.
* Flashed message fonts are updated. The blue font now uses softer
  stroke and shadow colors and the same algorithm applies to the orange
  error flashes.

Some other changes to player physics:

* Max velocity, acceleration speed, and gravity have been tweaked.
* Fast turn-around if you are moving right and then need to go left.
  Your velocity resets to zero at the transition so you quickly get
  going the way you want to go.

Some levels that need a bit of love for the new platforming physics:

* Tutorial 3.level

837960c477 Doodads: Small Key Door + Bigger Crumbly Floor
* The crumbly floor doodad was made 50% larger.
* New doodad: Small Key and Small Key Door. These work like the colored
  doors and locks except each Small Key is consumed when it unlocks a
  door. The door's appearance is of iron bars.
* The inventory HUD displays a small quantity label in the lower-right
  corner of items that have a quantity, such as the Small Key. This is
  done as a Canvas.CornerLabel string attribute on uix.Canvas.
* The "give all keys" cheat adds 99 Small Keys to your inventory.

08e65c32b5 Overhaul the Platformer Physics System
* Player character now experiences acceleration and friction when
  walking around the map!
* Actor position and movement had to be converted from int's
  (render.Point) to float64's to support fine-grained acceleration
  steps.
* Added "physics" package and physics.Vector to be a float64 counterpart
  for render.Point. Vector is used for uix.Actor.Position() for the sake
  of movement math. Vector is flattened back to a render.Point for
  collision purposes, since the levels and hitboxes are pixel-bound.
* Refactor the uix.Actor to no longer extend the doodads.Drawing (so it
  can have a Position that's a Vector instead of a Point). This broke
  some code that expected `.Doodad` to directly reference the
  Drawing.Doodad: now you had to refer to it as `a.Drawing.Doodad` which
  was ugly. Added convenience method .Doodad() for a shortcut.
* Moved functions like GetBoundingRect() from doodads package to
  collision, where it uses its own slimmer Actor interface for just the
  relevant methods it needs.

c3d7348843 Inventory System for Level Actors
* Added an inventory system for actors as a replacement to the arbitrary
  key/value data store. Colored keys now add themselves to the player's
  inventory, and colored doors check the inventory.
* Inventory is a map[string]int between doodad filenames
  (red-key.doodad) and quantity (0 for key items/unlimited qty).
* API methods to add and remove inventory.
* Items HUD appears in Play Mode in lower-left corner showing doodad
  sprites of all the items in the Player's inventory.
