- Breaking change: Rename config file to svgedit-config-iife.js (or for the module version, svgedit-config-es.js);

also expect one directory higher; incorporates #207 (@iuyiuy)
- Breaking change: Separate `extIconsPath` from `extPath` (not copying over icons)
- Breaking change: Don't reference `custom.css` in HTML; can instead be referenced in JavaScript through
    the config file (provided in `svgedit-config-sample-iife.js`/`svgedit-config-sample-es.js` as `svgedit-custom.css` for
    better namespacing); incorporates #207 (@iuyiuy)
- Breaking change: Remove minified jgraduate/spinbtn files (minified within Rollup routine)
- Fix: Zoom when scrolled; incorporates #169 (@AndrolGenhald), adapting for conventions; also allow avoidance when shift key pressed
- Fix: Update Atom feed reference in HTML
- Fixes related to recent commits: Some path and method name fixes needed, function order, missing methods, variable scope declaration, no need for DOMContentLoaded listeners in modules, switch back to non-default export, avoid trimming nullish, deal with mock tests, fix `math.matrixMultiply`, use jquery-svg where needed for array/SVG attributes; add babel-polyfill and defer script to imagelib; other misc. fixes
- Enhancement: Move config-sample.js out of `editor` directory
- Enhancement: For `callback`-style extensions, also provide config object; add following
   to that object: buildCanvgCallback, canvg, decode64, encode64, executeAfterLoads, getTypeMap, isChrome, ieIE, NS, text2xml
- Enhancement: Complete ES6 modules work (extensions, locales, tests), along with Babel;
    make Node build routine for converting modular source to non-modular,
    use `loadStylesheets` for modular stylehsheet defining (but parallel loading);
- Enhancement: Add `stylesheets` config for modular but parallel stylesheet loading with `@default` option for simple inclusion/exclusion of defaults (if not going with default).
- Refactoring: Clean up `svg-editor.html`: consistent indents; avoid extra lbs, avoid long lines
- Refactoring: Avoid embedded API adding inline JavaScript listener
- Refactoring: Move layers and context code to `draw.js`
- Refactoring: Move `pathActions` from `svgcanvas.js` (though preserve aliases to these methods on `canvas`) and `convertPath` from `svgutils.js` to `path.js`
- Refactoring: Move `getStrokedBBox` from `svgcanvas.js` (while keeping an alias) to `svgutils.js` (as `getStrokedBBoxDefaultVisible` to avoid conflict with existing)
- Docs: Remove "dependencies" comments in code except where summarizing role of jQuery or a non-obvious dependency
- Refactoring/Linting: Enfore `no-extra-semi` and `quote-props` rules
- Refactoring: Further avoidance of quotes on properties (as possible)
- Refactoring: Use `class` in place of functions where intended as classes
- Refactoring: Consistency and granularity in extensions imports
- Testing: Update QUnit to 2.6.1 (node_modules) and Sinon to 5.0.8 (and add sinon-test at 2.1.3) and enforce eslint-plugin-qunit linting rules; update custom extensions
- Testing: Add node-static for automating (and accessing out-of-directory contents)
- Testing: Avoid HTML attributes for styling
- Testing: Add npm `test` script
- Testing: Comment out unused jQuery SVG test
- Testing: Add test1 and svgutils_performance_test to all tests page
- Testing: Due apparently to Path having not been a formal class, the test was calling it without `new`; refactored now with sufficient mock data to take into account it is a class
- npm: Update devDeps
- npm: Add html modules and config build to test script
