In order to achieve\n // compression, values greater then the input range (codes can be up to\n // 12-bit while input only 8-bit) represent a sequence of previously seen\n // inputs. The decompressor is able to build the same mapping while\n // decoding, so there is always a shared common knowledge between the\n // encoding and decoder, which is also important for \"timing\" aspects like\n // how to handle variable bit width code encoding.\n //\n // One obvious but very important consequence of the table system is there\n // is always a unique id (at most 12-bits) to map the runs. 'A' might be\n // 4, then 'AA' might be 10, 'AAA' 11, 'AAAA' 12, etc. This relationship\n // can be used for an effecient lookup strategy for the code mapping. We\n // need to know if a run has been seen before, and be able to map that run\n // to the output code. Since we start with known unique ids (input bytes),\n // and then from those build more unique ids (table entries), we can\n // continue this chain (almost like a linked list) to always have small\n // integer values that represent the current byte chains in the encoder.\n // This means instead of tracking the input bytes (AAAABCD) to know our\n // current state, we can track the table entry for AAAABC (it is guaranteed\n // to exist by the nature of the algorithm) and the next character D.\n // Therefor the tuple of (table_entry, byte) is guaranteed to also be\n // unique. This allows us to create a simple lookup key for mapping input\n // sequences to codes (table indices) without having to store or search\n // any of the code sequences. So if 'AAAA' has a table entry of 12, the\n // tuple of ('AAAA', K) for any input byte K will be unique, and can be our\n // key.

Event listeners and inline computing\n * functions in the template will be called on the host of the template.\n *\n * The constructor returned takes a single argument dictionary of initial\n * property values to propagate into template bindings. Additionally\n * host properties can be forwarded in, and instance properties can be\n * notified out by providing optional callbacks in the `options` dictionary.\n *\n * Valid configuration in `options` are as follows:\n *\n * - `forwardHostProp(property, value)`: Called when a property referenced\n * in the template changed on the template's host. As this library does\n * not retain references to templates instanced by the user, it is the\n * templatize owner's responsibility to forward host property changes into\n * user-stamped instances. The `instance.forwardHostProp(property, value)`\n * method on the generated class should be called to forward host\n * properties into the template to prevent unnecessary property-changed\n * notifications. Any properties referenced in the template that are not\n * defined in `instanceProps` will be notified up to the template's host\n * automatically.\n * - `instanceProps`: Dictionary of property names that will be added\n * to the instance by the templatize owner. These properties shadow any\n * host properties, and changes within the template to these properties\n * will result in `notifyInstanceProp` being called.\n * - `mutableData`: When `true`, the generated class will skip strict\n * dirty-checking for objects and arrays (always consider them to be\n * \"dirty\").\n * - `notifyInstanceProp(instance, property, value)`: Called when\n * an instance property changes. Users may choose to call `notifyPath`\n * on e.g. the owner to notify the change.\n * - `parentModel`: When `true`, events handled by declarative event listeners\n * (`on-event=\"handler\"`) will be decorated with a `model` property pointing\n * to the template instance that stamped it. It will also be returned\n * from `instance.parentModel` in cases where template instance nesting\n * causes an inner model to shadow an outer model.\n *\n * All callbacks are called bound to the `owner`. Any context\n * needed for the callbacks (such as references to `instances` stamped)\n * should be stored on the `owner` such that they can be retrieved via\n * `this`.\n *\n * When `options.forwardHostProp` is declared as an option, any properties\n * referenced in the template will be automatically forwarded from the host of\n * the `` to instances, with the exception of any properties listed in\n * the `options.instanceProps` object. `instanceProps` are assumed to be\n * managed by the owner of the instances, either passed into the constructor\n * or set after the fact. Note, any properties passed into the constructor will\n * always be set to the instance (regardless of whether they would normally\n * be forwarded from the host).\n *\n * Note that `templatize()` can be run only once for a given ``.\n * Further calls will result in an error. Also, there is a special\n * behavior if the template was duplicated through a mechanism such as\n * `` or ``. In this case, all calls to\n * `templatize()` return the same class for all duplicates of a template.\n * The class returned from `templatize()` is generated only once using\n * the `options` from the first call.

` is a Web Component for creating overlays. The content of the overlay\n * can be populated in two ways: imperatively by using renderer callback function and\n * declaratively by using Polymer's Templates.\n *\n * ### Rendering\n *\n * By default, the overlay uses the content provided by using the renderer callback function.\n *\n * The renderer function provides `root`, `owner`, `model` arguments when applicable.\n * Generate DOM content by using `model` object properties if needed, append it to the `root`\n * element and control the state of the host element by accessing `owner`. Before generating new\n * content, users are able to check if there is already content in `root` for reusing it.\n *\n * ```html\n * ` content is not used.\n *\n * ### Templating\n *\n * Alternatively, the content can be provided with Polymer Template.\n * Overlay finds the first child template and uses that in case renderer callback function\n * is not provided. You can also set a custom template using the `template` property.\n *\n * After the content from the template is stamped, the `content` property\n * points to the content container.\n *\n * The overlay provides `forwardHostProp` when calling\n * `Polymer.Templatize.templatize` for the template, so that the bindings\n * from the parent scope propagate to the content.\n *\n * ### Styling\n *\n * To style the overlay content, use styles in the parent scope:\n *\n * - If the overlay is used in a component, then the component styles\n * apply the overlay content.\n * - If the overlay is used in the global DOM scope, then global styles\n * apply to the overlay content.\n *\n * See examples for styling the overlay content in the live demos.\n *\n * The following Shadow DOM parts are available for styling the overlay component itself:\n *\n * Part name | Description\n * -----------|---------------------------------------------------------|\n * `backdrop` | Backdrop of the overlay\n * `overlay` | Container for position/sizing/alignment of the content\n * `content` | Content of the overlay\n *\n * The following state attributes are available for styling:\n *\n * Attribute | Description | Part\n * ---|---|---\n * `opening` | Applied just after the overlay is attached to the DOM. You can apply a CSS @keyframe animation for this state. | `:host`\n * `closing` | Applied just before the overlay is detached from the DOM. You can apply a CSS @keyframe animation for this state. | `:host`\n *\n * The following custom CSS properties are available for styling:\n *\n * Custom CSS property | Description | Default value\n * ---|---|---\n * `--vaadin-overlay-viewport-bottom` | Bottom offset of the visible viewport area | `0` or detected offset\n *\n * See [Styling Components](https://vaadin.com/docs/latest/styling/custom-theme/styling-components) documentation.\n *\n * @fires {CustomEvent} opened-changed - Fired when the `opened` property changes.\n * @fires {CustomEvent} vaadin-overlay-open - Fired after the overlay is opened.\n * @fires {CustomEvent} vaadin-overlay-close - Fired before the overlay will be closed. If canceled the closing of the overlay is canceled as well.\n * @fires {CustomEvent} vaadin-overlay-closing - Fired when the overlay will be closed.\n * @fires {CustomEvent} vaadin-overlay-outside-click - Fired before the overlay will be closed on outside click. If canceled the closing of the overlay is canceled as well.\n * @fires {CustomEvent} vaadin-overlay-escape-press - Fired before the overlay will be closed on ESC button press.
