Handling this event is part of the API but was never done. This caused
unstoppable key-repeat.
This event isn't common, the only way I found on Android 10 is to switch
to the emoji keyboard while holding a key. Some apps might cause this
event more often.
* Clicking twice on CTRL or ALT will lock them in 'ON' state
* Make Locking behaviour optional, configurable in preferences
* Nest the new settings into a different page
To avoid spamming the settings page and repetition in the summaries.
Cannot be a popup unfortunately because that would require API >= 11.
* Add Fn and Meta

The symbols are now smaller for Shift, Space, Backspace, Delete and
some keys on the bottom row.
The previous rule was to make the text smaller for symbols made of
several characters.
This is changed to a flag approach.
Use the height of the row currently being rendered instead of the base
row size.
Concretely, the bottom row is slightly smaller and will get slightly
smaller text.
Also:
- Rewrite the label rendering code
- Render labels at the middle of the key (was slightly off)
Instead of a fixed size that don't work at all for bigger screens.
Other tweaks:
- Use the value-land dimens to vary 'extra_horizontal_margin'
- Move label size to Config, because it can change at runtime (rotation)
- Slightly decrease the size of "long" symbols
Before sending a key event while modifiers are active, send events for
the modifier keys.
Some applications don't look at the "metaState" flags but instead keep
track of the up and down events for the modifiers.
For example, the basic text views that are in every applications
correctly handle the "metaState" flags except for one binding:
Selecting text with the arrows while pressing shift.
Change the formula: don't use an external constant, add a state.
It's now the ratio between where the finger is at the first repeat and
where it is now.
Keep the repeat going when swiping into an other key. Currently only for
arrows: It's now possible to go from an arrow to an other without
waiting again for the key repeat timeout.
The backspace and delete keys don't work well with this.
Show these characters only for users that have the corresponding locale
installed (a supported eu language for €, en-GB for £).
Add these characters to most layouts.
Depending on the pixel density isn't ideal for a keyboard, which would
render differently depending on the "scaling" accessibility option.
Landscape mode needs a special values. At the same time, increase the
horizontal margin when landscape.
Add a new boolean parameter "edgekeys" for defining keys that have the
additional (swipe) keys on the edges (top, right, left, bottom) instead
of at the corners (top left, top right, bottom left, bottom right).
Currently using the diamond symbol like the history meta key: https://en.wikipedia.org/wiki/Meta_key
However, this key is actually interpreted as the Super/Windows key but
Android calls it "meta" internally.
There were two problems:
- The Action key was swapped when it shouldn't be. The flag
'IME_FLAG_NO_ENTER_ACTION' wasn't interpreted correctly for inputs
that specified both an action and this flag.
- The value 'IME_ACTION_UNSPECIFIED' should remove the Action key.
A customised Latvian specific QWERTY layout (QWERTY (Latvian)) was added
to access all Latvian diacritic characters with a swipe.
Additionally caron, cedille and macron accents were enabled for this
layout.
'keyVerticalInterval' was mistakenly used to compute the height of the
keyboard and the vertical position of keys.
While the code handling pointers did not use this value, the hit box of
the bottom row was shifted by several pixels.
Make sure 'keyVerticalInterval' is only used for rendering and not for
placing the keys.
It is placed on the top-right of the enter key on every layouts.
It sends a special event (performEditorAction) instead of writing a
newline.
The "actionId" is passed through the EditorInfo object in an obfuscated
way so it's not clear whether it's using the right one.
