| auto-refresh.js |
Base class for auto-refresh-on-change highlighters. Sub classes will have a
chance to update whenever the current node's geometry changes.
Sub classes must implement the following methods:
_show: called when the highlighter should be shown,
_hide: called when the highlighter should be hidden,
_update: called while the highlighter is shown and the geometry of the
current node changes.
Sub classes will have access to the following properties:
- this.currentNode: the node to be shown
- this.currentQuads: all of the node's box model region quads
- this.win: the current window
Emits the following events:
- shown
- hidden
- updated

| box-model.js |
The BoxModelHighlighter draws the box model regions on top of a node.
If the node is a block box, then each region will be displayed as 1 polygon.
If the node is an inline box though, each region may be represented by 1 or
more polygons, depending on how many line boxes the inline element has.
Usage example:
let h = new BoxModelHighlighter(env);
h.show(node, options);
h.hide();
h.destroy();
@param {String} options.region
Specifies the region that the guides should outline:
"content" (default), "padding", "border" or "margin".
@param {Boolean} options.hideGuides
Defaults to false
@param {Boolean} options.hideInfoBar
Defaults to false
@param {String} options.showOnly
If set, only this region will be highlighted. Use with onlyRegionArea
to only highlight the area of the region:
"content", "padding", "border" or "margin"
@param {Boolean} options.onlyRegionArea
This can be set to true to make each region's box only highlight the
area of the corresponding region rather than the area of nested
regions too. This is useful when used with showOnly.

| shapes.js |
The ShapesHighlighter draws an outline shapes in the page.
The idea is to have something that is able to wrap complex shapes for css properties
such as shape-outside/inside, clip-path but also SVG elements.
Notes on shape transformation:
When using transform mode to translate, scale, and rotate shapes, a transformation
matrix keeps track of the transformations done to the original shape. When the
highlighter is toggled on/off or between transform mode and point editing mode,
the transformations applied to the shape become permanent.
While transformations are being performed on a shape, there is an "original" and
a "transformed" coordinate system. This is used when scaling or rotating a rotated
shape.
The "original" coordinate system is the one where (0,0) is at the top left corner
of the page, the x axis is horizontal, and the y axis is vertical.
The "transformed" coordinate system is the one where (0,0) is at the top left
corner of the current shape. The x axis follows the north edge of the shape
(from the northwest corner to the northeast corner) and the y axis follows
the west edge of the shape (from the northwest corner to the southwest corner).
Because of rotation, the "north" and "west" edges might not actually be at the
top and left of the transformed shape. Imagine that the compass directions are
also rotated along with the shape.
A refresher for coordinates and change of basis that may be helpful:
