The multiplication by 99 can overflow an int8_t depending on whether the
expression is coerced to a regular-sized int (based on the 99 literal).
Just to be safe, perform a cast to int16_t in case the coercion does not
happen.
Previously, diagonal movements were not reduced in the two axes,
resulting in movement that was too quick. This commit divides diagonal
movements by sqrt(2) / 2 to correct the movement speed.
The net result is that diagonal movement should feel smoother and speed
more as expected.
This removes WakeupKeyboard, because a similar feature was integrated into
BootKeyboard itself, rendering it useless.
See keyboardio/KeyboardioHID#35 for an explanation of the whole situation.

Instead of repeating the same cRGB reading code in three places, use the
recently introduced Focus.readColor() function. This both makes the code
cleaner, and more than 50 bytes smaller too.

Instead of using a lambda (which is not constexpr in C++11), use a temporary,
anonymous struct instance to wrap the `static_assert`, which is constexpr in
C++11.
Fixeskeyboardio/Model01-Firmware#53. Thanks to @noseglasses for finding the
cause, and explaining the fix!

Many plugins use timers, and most of them will call `millis()`, which isn't
wrong, but isn't the most efficient either. While `millis()` isn't terribly
expensive, it's not cheap either. For most cases, we do not need an exact timer,
and one updated once per cycle is enough - which is what `.millisAtCycleStart()`
is. Having a timer that is consistent throughout the whole cycle may also be
beneficial.

Use ./_build/ for the build path by default, and do not delete it at the end of
compilation, only when doing a clean.
Fixes#315.

Instead of a twisted combination, use the palm keys - easy to press, and
otherwise unused in the example. Also, use `Macros.type` instead of
`Serial.println`, because the former is easier to play with as a user.
Fixes#5.

Instead of hardcoding the max program size, pick it out of boards.txt, like we
pick the device VID and PID.

The member functions of the union now take all arguments const, meaning
that it is not possible to modify this value somehow. This reduces the
chance of subtle bugs and widens the contexts in which these member
functions can be used.
Furthermore, one signature took a `Key' by value while all functions
take `Key' by reference. For the sake of consistency, this was adapted
to.
Making the member functions of Key `const' explicitly flags that they
will not change the union. This will allow to use Key in const contexts.
Adding the `constexpr' specifier to the function makes it possible to
rely on the results at compile time. This puts some kind of restrictions
on the function, especially when using C++11 and not a newer standard,
but these restrictions were already fulfilled, so this seems to be safe.
Updates the formatting a bit, and adds a few entries too. Still much to be done,
but... small steps!
