launcher: Animated vector describing swipe gesture

Replace the short video with an animated vector image that shows the
swipe gesture.

This is much lighter and reliable than the mp4 video, which failed to
play on many devices.

Source for the image of the key is in inkscape SVG format in srcs/res
and is converted to an android drawable when needed. The swipe animation
is hand-written.

+# Custom layouts
+You select a key layout for Unexpected Keyboard by calling up the Settings page (swipe the gear icon) and, at the top of the page, either tapping an existing layout or tapping _Add an alternate layout_. This displays a menu of available layouts. You can define your own layout by choosing _Custom layout_ at the bottom of this menu. Unexpected Keyboard now displays code in the XML format. You make changes by replacing this with different code and tapping OK.
+
+We recommend you keep your work in a file outside Unexpected Keyboard (named something like `MyChanges.xml`). If you installed a new version of Unexpected from a different website (with a different signature), then the work you did solely by editing the XML inside Unexpected would be lost.
+
+Put initial contents into your file in one of these ways:
+* Copypaste the code Unexpected displays for _Custom layout_.
+* Make a copy of one of the built-in layouts found in [`/srcs/layouts`](https://github.com/Julow/Unexpected-Keyboard/tree/master/srcs/layouts).
+* Use the [web-based editor](https://unexpected-keyboard-layout-editor.lixquid.com/). Interact with this web page to define keys and swipes and move keys to desired positions, and it will write the XML code for you. You can make the web page put the XML in a text file or copy it to the clipboard.
+
+When you have prepared suitable XML code in one of these ways, copy it to the clipboard and paste it into Unexpected Keyboard.
+
+## XML language overview
+A layout XML file comprises tags that start with `<` and end with `>`.
+* Every layout file starts with this declaration:
+  `<?xml version="1.0" encoding="utf-8"?>`
+* Certain tags come in pairs—an opening tag and a closing tag—and apply to everything between them.
+  * The `<keyboard>`...`</keyboard>` pair says that the material between them is the definition of your keyboard. There can be only one of these.
+  * The `<row>`...`</row>` pair encloses the definition of a single row.
+  * An optional `<modmap>`...`</modmap>` pair contains instructions if you want to change the behavior of a modifier key such as Shift.
+* Stand-alone tags include `<key`...`/>`, which defines a single key.
+
+A tag can have properties, defined using an equals sign and a pair of ASCII double quotes. For example, `<key key0="a" />` defines the "a" key. The `key0` property of the `key` tag says which key you are defining, and the tag's location inside `<row>`...`</row>` specifies where it will go in the row.
+
+### Example
+Here is a complete keyboard file with a single row containing an "a" key on the left and a "b" key on the right:
+
+    <?xml version="1.0" encoding="utf-8"?>
+    <keyboard name="Simple example" script="latin">
+        <row>
+            <key key0="a" />
+            <key key0="b" />
+        </row>
+    </keyboard>
+
+## Keyboard metadata
+
+The `<keyboard>`...`</keyboard>` pair follows the declaration tag and encloses the whole keyboard. The following properties may be used (The first two appear in the example above):
+
+* `name`: The name of the keyboard. The name you specify will appear in the Settings menu. If not present, the layout will just appear as “Custom layout”.
+
+* `script`: The (main) writing system that the keyboard supports. The possible values are `arabic`, `armenian`, `bengali`, `cyrillic`, `devanagari`, `gujarati`, `hangul`, `hebrew`, `latin`, `persian`, `shavian`, and `urdu`. It defaults to `latin`.
+
+* `numpad_script`: The script to use for the numpad. This is useful for scripts where a different, non-ASCII set of numerals is used, like Devanagari and Arabic. It defaults to the same as `script`.
+
+* `bottom_row`: Whether or not to show the built-in bottom row. It accepts `true` or `false`, and defaults to `true`. If your custom layout defines the bottom row, then specify `bottom_row="false"` to disable the built-in bottom row.
+  + We recommend your layout use the built-in bottom row, because it is still evolving and your layout will incorporate innovations in future versions. However, to define your own, the current definition of the bottom row is in [bottom_row.xml](https://github.com/Julow/Unexpected-Keyboard/res/xml/bottom_row.xml). You can copypaste this XML into your custom layout as a starting point.
+  + Likewise, the current definition of the top (number) row is in [number_row.xml](https://github.com/Julow/Unexpected-Keyboard/res/xml/number_row.xml).
+
+* `locale_extra_keys`: Whether Unexpected should add language-dependent extra keys from [method.xml](../res/xml/method.xml) to this layout. It accepts `true` or `false`, and defaults to `true`. To disable these automatic additions, specify `locale_extra_keys="false"`.
+
+## Row
+The `<row>`...`</row>` pair encloses one row on the keyboard. It has only one optional property:
+* `height`: The height of the row: a positive floating-point value.
+
+A row's default height is 1.0 (one quarter of the keyboard height specified on the Settings menu). The `height` property makes the row taller or shorter than this. For example, if you define a 5-row keyboard but one row has `height="0.7"`, then the keyboard's total height is 4.7 units. If the total is different from 4.0, the keyboard will be taller or shorter than that specified in Settings.
+
+## Key
+The `<key />` tag defines a key on the keyboard. Its position in the sequence of keys inside `<row>`...`</row>` indicates its position in the row from left to right. What the key does is defined by optional properties.
+
+### Taps
+What the key does when tapped is defined by the optional `key0` property. For example, `<key key0="a" />` defines the "a" key. Unexpected Keyboard provides a legend in the middle of the key.
+
+When the Shift modifier is tapped, the "a" key becomes the "A" key and the legend temporarily changes. The Fn modifier makes a different change. You can override this behavior with a modmap (see below).
+
+### Swipes
+The following optional properties define the effects of swipes:
+* `n`, `ne`, `e`, `se`, `s`, `sw`, `w`, `nw`: What the key should do when it is swiped in the direction of that compass point. ("North" means upward and "East" is to the right.)
+<TABLE ALIGN=CENTER>
+  <TR>
+    <TD STYLE="width: 6em;">nw</TD><TD>n</TD><TD>ne</TD>
+  </TR>
+  <TR ALIGN=CENTER>
+    <TD>w</TD><TD>&nbsp;</TD><TD>e</TD>
+  </TR>
+  <TR>
+    <TD>sw</TD><TD>s</TD><TD>se</TD>
+  </TR>
+</TABLE>
+
+* `key1` through `key8` is an older way to achieve the same effects. The directions are ordered as follows:
+<TABLE ALIGN=CENTER>
+  <TR>
+    <TD>key1</TD><TD>key7</TD><TD>key2</TD>
+  </TR>
+  <TR>
+    <TD>key5</TD><TD>&nbsp;</TD><TD>key6</TD>
+  </TR>
+  <TR>
+    <TD>key3</TD><TD>key8</TD><TD>key4</TD>
+  </TR>
+</TABLE>
+
+You can define a swipe only once with either compass-point or numeric notation. Unexpected Keyboard automatically puts a small legend in that direction from the center of the key.
+
+* `slider`: If `slider="true"`, and the key also has `w` and `e` properties, then the key tracks horizontal finger motion precisely and sends the `w` and `e` keystrokes repeatedly. In built-in layouts, this makes the space bar send left and right characters as the user slides on the space bar.
+* `anticircle`: The key value to send when doing an anti-clockwise gesture on the key.
+
+### Layout
+A key may have the following properties to control the row's layout:
+* `width`: The width of the key, a positive floating-point value. It defaults to 1.0
+* `shift`: How much empty space to add to the left of this key, a non-negative floating-point value. It defaults to 0.0
+
+Normally, a key's width is 1.0 unit. Unexpected Keyboard occupies the full width of the screen, and the row defining the highest number of units (in widths plus shifts) is as wide as the screen. A row whose width is a smaller number of units has empty space on the right.
+
+### Extra legend
+* `indication`: An optional extra legend to show under the main label. For example, `<key key0="2" indication="ABC" />` displays ABC at the bottom of the 2 key, as on a pinpad or some telephones. If the key also defines a downward swipe with `s` or `key8`, the legends overlap.
+
+### Possible key values
+Built-in strings that assign a special function to a key are described in [this page](Possible-key-values.md). For example, `se="copy"` means a southeasterly swipe produces the Copy key. If a key value does not match any of the built-in strings, it outputs that text _verbatim_. For example, `key0="a"` simply outputs the letter a.
+
+In a layout, a key value can also start with the `loc` prefix. These are place-holders; the tap or swipe does nothing unless enabled through the "Add keys to keyboard" option in the Settings menu, or implicitly enabled by the language the device is set to use. For example, `ne="loc accent_aigu"` says that a northeast swipe produces the acute accent combinatorial key—if enabled.
+
+## Modmap
+The `<modmap>`...`</modmap>` pair encloses custom mappings for modifier keys. The modmap is placed inside the `<keyboard>`...`</keyboard>` pair, but outside any row. A layout can have at most one modmap. It can contain any number of mappings. Each mapping has an `a` property and a `b` property and maps the `a` key to the `b` key. Valid values are listed in [Possible key values](Possible-key-values.md).
+
+The following mappings are supported:
+
+```xml
+  <shift a="before" b="after" />
+```
+This means that when the Shift modifier is on, the key `before` is changed into `after`.
+
+```xml
+  <fn a="before" b="after" />
+```
+This means that when the Fn modifier is on, the key `before` is changed into `after`.
+
+```xml
+  <ctrl a="before" b="after" />
+```
+This means that when the Ctrl modifier is on, the key `before` is changed into `after`. The `<ctrl />` mapping is special in that the Ctrl modifier is applied to `after` after the mapping.
+
+The clockwise circle and the round-trip gestures are affected by both `<shift />` and `<fn />` mappings. The Shift mappings are used first and if that did not modify the key, the Fn mappings are used instead.
+
+### Examples
+① Turkish keyboards use the Latin alphabet, but when "i" is shifted, it should produce "İ". This is achieved with the following mapping: 
+
+```xml
+    <shift a="i" b="İ" />
+```
+② Cyrillic layouts have no V key. A layout can define Ctrl-V with the following mapping:
+
+```xml
+    <ctrl a="в" b="v" />
+```
+This maps Ctrl+в to Ctrl+V—not to v.
+
+## Portrait vs. landscape
+Unexpected Keyboard remembers *separately* which layout has last been used in portrait and landscape orientation. So you may have one custom layout for portrait orientation, but another custom layout for landscape orientation, and Unexpected Keyboard will switch between them without your intervention.
+
+## Contributing your layout
+The Unexpected Keyboard project enthusiastically accepts user contributions, including custom layouts. (See the guidance for layouts at [CONTRIBUTING.md](https://github.com/Julow/Unexpected-Keyboard/blob/master/CONTRIBUTING.md#Adding-a-layout)).
+* Submit a layout that has innovations of possible interest to other users at [Unexpected-Keyboard-layouts](https://github.com/Julow/Unexpected-Keyboard-layouts).
+* Propose that your layout be included in the set of built-in layouts by making a Pull Request for an addition to [srcs/layouts](https://github.com/Julow/Unexpected-Keyboard/tree/master/srcs/layouts). Please show that such a layout is standard in your locale or has a substantial number of users.

+# Key values
+
+This is an exhaustive list of special values accepted for the `key0` through `key8` or `nw` through `se` attributes on a key.
+
+Any string that does not exactly match these will be printed verbatim.
+A key can output multiple characters, but cannot combine multiple built-in key values.
+
+## Escape codes
+Value | Escape code for
+:---- | :------
+`\?`  | `?`
+`\#`  | `#`
+`\@`  | `@`
+`\n`  | Literal newline character. This is different from `enter` and `action` in certain apps.
+`\t`  | Literal tab character. This is different from `tab` in certain apps.
+`\\`  | `\`
+
+XML escape codes also work, including:
+
+Value    | Escape code for

+`compose`   | Compose key. Enables composing characters using Linux-like shortcuts; e.g. `Compose` `A` `single quote` types `Á` (A with acute accent).
+`capslock`  | Actives and locks Shift
+
+## Special keys

+`change_method_prev`   | Switch to the previously used input method.
+`action`               | Performs a special context-sensitive operation related to the Enter key. For example, in the Twitter (X) app, `enter` adds a new line, while `action` posts.
+`voice_typing`         | Begin voice typing.
+`voice_typing_chooser` | Shows a menu where you can choose which voice typing provider to use, then begins voice typing when you make a selection.
+`shareText`            | Emit a share Intent for the selected text. **Oddity:** This is in CamelCase.
+
+## Unused
+These keys are known to do nothing.
+
+`replaceText`, `textAssist`,
+`autofill`, `removed`
+
+## Placeholders
+These keys are normally hidden unless the Fn modifier is activated.
+
+`f11_placeholder` | `f12_placeholder`
+
+## Complex keys
+
+More complex keys are of this form:
+
+```
+:<kind> <attributes>:<payload>
+```
+
+Where `<kind>` is one of the kinds documented below and `<attributes>` is a
+space separated list of attributes. `<payload>` depends on the `<kind>`.
+
+Attributes are:
+- `symbol='Sym'` specifies the symbol to be shown on the keyboard.
+- `flags='<flags>'` changes the behavior of the key.
+  `<flags>` is a coma separated list of:
+  + `dim`: Make the symbol dimmer.
+  + `small`: Make the symbol smaller.
+
+### Kind `str`
+
+Defines a key that outputs an arbitrary string. `<payload>` is a string wrapped
+in single-quotes (`'`), escaping of other single quotes is allowed with `\'`.
+
+For example:
+- `:str:'Arbitrary string with a \' inside'`
+- `:str symbol='Symbol':'Output string'`
+
+### Kind `char`
+
+Defines a key that outputs a single character. `<payload>` is the character to
+output, unquoted.
+This kind of key can be used to define a character key with a different symbol
+on it. `char` keys can be modified by `ctrl` and other modifiers, unlike `str`
+keys.
+
+For example:
+- `:char symbol='q':љ`, which is used to implement `ctrl` shortcuts in cyrillic
+  layouts.
