0c6c77a423 Lemon-shaped Ellipse Tool (WIP)
* Add initial Ellipse Tool to the Editor Mode. Currently there's
  something wrong with the algorithm and the ellipses have a sort of
  'lemon shape' to them.
* Refactor the IterLine/IterLine2 functions to be more consistent.
  IterLine used to be the raw algorithm that took a bunch of coordinate
  numbers and IterLine2 took two render.Point's and was the main one
  used throughout the app. Now, IterLine takes the two Points and the
  raw algorithm function removed.

cc1e441232 Eraser Tool, Brush Sizes
* Implement Brush Sizes for drawtool.Stroke and add a UI to the tools panel
  to control the brush size.
  * Brush sizes: 1, 2, 4, 8, 16, 24, 32, 48, 64
* Add the Eraser Tool to editor mode. It uses a default brush size of 16
  and a max size of 32 due to some performance issues.
* The Undo/Redo system now remembers the original color of pixels when
  you change them, so that Undo will set them back how they were instead
  of deleting the pixel entirely. Due to performance issues, this only
  happens when your Brush Size is 0 (drawing single-pixel shapes).
* UI: Add an IntVariable option to ui.Label to bind showing the value of
  an int reference.

Aforementioned performance issues:

* When we try to remember whole rects of pixels for drawing thick
  shapes, it requires a ton of scanning for each step of the shape. Even
  de-duplicating pixel checks, tons of extra reads are constantly
  checked.
* The Eraser is the only tool that absolutely needs to be able to
  remember wiped pixels AND have large brush sizes. The performance
  sucks and lags a bit if you erase a lot all at once, but it's a
  trade-off for now.
* So pixels aren't remembered when drawing lines in your level with
  thick brushes, so the Undo action will simply delete your pixels and not
  reset them. Only the Eraser can bring back pixels.

22440f436b Add Scrolling in the Doodad Palette Window
* Rudimentary scrolling shows a Left and Right button at the top of the
  Doodad Palette if your window is deemed not tall enough to contain all
  of the doodads.
* A "progress bar" is shown between the buttons indicating the
  percentage of your scroll down the doodad list. When you're able to
  see the final row of doodads, the progress bar is at 100%.

12d34517e9 Add Tool Bar to Editor Mode
* Toolbar has icon buttons for the Pencil Tool, Line Tool, Rect Tool,
  Actor Tool and Link Tool.
* Remove the tab buttons from the top of the Palette window. The palette
  tab is now toggled between Swatches and Doodads by the tool selected
  on the tool bar, instead of the tab buttons setting the tool.
* Remove the "Link Doodads" button from the Doodad Palette. The Link
  Tool has its own dedicated toolbar button with the others.
