Create the SVG master file that includes all icons:\n\nThe master SVG icon-containing file is an SVG file that contains\n`<g>` elements. Each `<g>` element should contain the markup of an SVG\nicon. The `<g>` element has an ID that should\ncorrespond with the ID of the HTML element used on the page that should contain\nor optionally be replaced by the icon. Additionally, one empty element should be\nadded at the end with id \"svg_eof\".\n\n2. Optionally create fallback raster images for each SVG icon.\n\n3. Include the jQuery and the SVG Icon Loader scripts on your page.\n\n4. Run `$.svgIcons()` when the document is ready. See its signature\n\n5. To access an icon at a later point without using the callback, use this:\n `$.getSvgIcon(id (string), uniqueClone (boolean))`;\n\nThis will return the icon (as jQuery object) with a given ID.\n\n6. To resize icons at a later point without using the callback, use this:\n `$.resizeSvgIcons(resizeOptions)` (use the same way as the \"resize\" parameter)\n *\n * @module jQuerySVGIcons\n * @license MIT\n * @copyright (c) 2009 Alexis Deveria\n * {@link http://a.deveria.com}\n * @example\n $(function () {\n $.svgIcons('my_icon_set.svg');

Note that as of version 2.7, this is not configurable by URL for security reasons.\n * @property {boolean} [preventAllURLConfig=false] Set to `true` to override the ability for URLs to set non-content configuration (including extension config). Must be set early, i.e., in `svgedit-config-iife.js`; extension loading is too late!\n * @property {boolean} [preventURLContentLoading=false] Set to `true` to override the ability for URLs to set URL-based SVG content. Must be set early, i.e., in `svgedit-config-iife.js`; extension loading is too late!\n * @property {boolean} [lockExtensions=false] Set to `true` to override the ability for URLs to set their own extensions; disallowed in URL setting.

Must be set early, i.e., in `svgedit-config-iife.js`; extension loading is too late!\n * @property {boolean} [noDefaultExtensions=false] If set to `true`, prohibits automatic inclusion of default extensions (though \"extensions\" can still be used to add back any desired default extensions along with any other extensions). This can only be meaningfully used in `svgedit-config-iife.js` or in the URL\n * @property {boolean} [noStorageOnLoad=false] Some interaction with `ext-storage.js`; prevent even the loading of previously saved local storage.\n * @property {boolean} [forceStorage=false] Some interaction with `ext-storage.js`; strongly discouraged from modification as it bypasses user privacy by preventing them from choosing whether to keep local storage or not (and may be required by law in some regions)\n * @property {boolean} [emptyStorageOnDecline=false] Used by `ext-storage.js`; empty any prior storage if the user declines to store\n * @property {boolean} [avoidClientSide=false] DEPRECATED (use `avoidClientSideDownload` instead); Used by `ext-server_opensave.js`; set to `true` if you wish to always save to server and not only as fallback when client support is lacking\n * @property {boolean} [avoidClientSideDownload=false] Used by `ext-server_opensave.js`; set to `true` if you wish to always save to server and not only as fallback when client support is lacking\n * @property {boolean} [avoidClientSideOpen=false] Used by `ext-server_opensave.js`; set to `true` if you wish to always open from the server and not only as fallback when FileReader client support is lacking\n * @property {string[]} [extensions=module:SVGEditor~defaultExtensions] Extensions to load on startup.

Note that as of version 2.7, paths containing \"/\", \"\\\", or \":\", are disallowed for security reasons. Although previous versions of this list would entirely override the default list, as of version 2.7, the defaults will always be added to this explicit list unless the configuration `noDefaultExtensions` is included.\n * @property {string[]} [allowedOrigins=[]] Used by `ext-xdomain-messaging.js` to indicate which origins are permitted for cross-domain messaging (e.g., between the embedded editor and main editor code). Besides explicit domains, one might add '*' to allow all domains (not recommended for privacy/data integrity of your user's content!), `window.location.origin` for allowing the same origin (should be safe if you trust all apps on your domain), 'null' to allow `file:///` URL usage\n * @property {null|PlainObject} [colorPickerCSS=null] Object of CSS properties mapped to values (for jQuery) to apply to the color picker. See {@link http://api.jquery.com/css/#css-properties}. A `null` value (the default) will cause the CSS to default to `left` with a position equal to that of the `fill_color` or `stroke_color` element minus 140, and a `bottom` equal to 40\n * @property {string} [paramurl] This was available via URL only. Allowed an un-encoded URL within the query string (use \"url\" or \"source\" with a data: URI instead)\n * @property {Float} [canvas_expansion=3] The minimum area visible outside the canvas, as a multiple of the image dimensions. The larger the number, the more one can scroll outside the canvas.\n * @property {PlainObject} [initFill] Init fill properties\n * @property {string} [initFill.color=\"FF0000\"] The initial fill color. Must be a hex code string. Defaults to solid red.\n * @property {Float} [initFill.opacity=1] The initial fill opacity. Must be a number between 0 and 1\n * @property {PlainObject} [initStroke] Init stroke properties\n * @property {Float} [initStroke.width=5] The initial stroke width. Must be a positive number.\n * @property {string} [initStroke.color=\"000000\"] The initial stroke color. Must be a hex code. Defaults to solid black.\n * @property {Float} [initStroke.opacity=1] The initial stroke opacity. Must be a number between 0 and 1.\n * @property {PlainObject} text Text style properties\n * @property {Float} [text.stroke_width=0] Text stroke width\n * @property {Float} [text.font_size=24] Text font size\n * @property {string} [text.font_family=\"serif\"] Text font family\n * @property {Float} [initOpacity=1] Initial opacity (multiplied by 100)\n * @property {module:SVGEditor.XYDimensions} [dimensions=[640, 480]] The default width/height of a new document. Use an array in `setConfig` (e.g., `[800, 600]`) and comma separated numbers in the URL.\n * @property {boolean} [gridSnapping=false] Enable snap to grid by default. Set in Editor Options.\n * @property {string} [gridColor=\"#000\"] Accepts hex, e.g., '#000'. Set in Editor Options. Defaults to black.\n * @property {string} [baseUnit=\"px\"] Set in Editor Options.\n * @property {Float} [snappingStep=10] Set the default grid snapping value. Set in Editor Options.\n * @property {boolean} [showRulers=true] Initial state of ruler display (v2.6). Set in Editor Options.\n * @property {string} [initTool=\"select\"] The initially selected tool. Must be either the ID of the button for the tool, or the ID without `tool_` prefix (e.g., \"select\").\n * @property {boolean} [wireframe=false] Start in wireframe mode\n * @property {boolean} [showlayers=false] Open the layers side-panel by default.\n * @property {\"new\"|\"same\"} [exportWindowType=\"new\"] Can be \"new\" or \"same\" to indicate whether new windows will be generated for each export; the `window.name` of the export window is namespaced based on the `canvasName` (and incremented if \"new\" is selected as the type). Introduced 2.8.\n * @property {boolean} [showGrid=false] Set by `ext-grid.js`; determines whether or not to show the grid by default\n * @property {boolean} [show_outside_canvas=true] Defines whether or not elements outside the canvas should be visible. Set and used in `svgcanvas.js`.\n * @property {boolean} [selectNew=true] If true, will replace the selection with the current element and automatically select element objects (when not in \"path\" mode) after they are created, showing their grips (v2.6).
