Currently the time is calculated 8 times per second from (relatively) slow
python code. Optimize the power consumed by reducing the number of times
we check for wall time updates to only once-per-second and use native
code generation to reduce VM overhead when executing this critical code.
At the time of writing the difference is battery life has not yet been
measured (but we know the current master branch is worse than v0.4 and,
in theory at least, this should close the gap).

wasp-os uses an drawing optimization technique to automatically place
a single pixel line on the right of glyphs when rendering them. This
results in a change to the bounding box for a rendered string (by adding
a single pixel on the right of the final character). Fix the bounding box
calculations accordingly. Among other things this eliminates graphical
artifacts when rendering labels in 2048.

When an application is registered using a string that gives the class
name (e.g. "apps.chrono.ChronoApp") when we automatically delete
the module from a couple of namespaces. This ensures the garbage
collector can do a deeper clean when the application is unregistered.
We also provide a means to directly register watch faces (e.g. to
replace the default clock).

Currently, if we ask the simulator to draw out-of-bounds then it will
do exactly that, it will draw outside of the "screen" and corrupt the
pixels of the watch frame that surrounds it. This is an obviously poor
simulation of the real watch and when the out-of-bounds error is only
an out-by-one error can be easily overlooked until we load the code on

Let's just throw an exception if we draw out-of-bounds. That can easily

wasp-os uses a rather eccentric "2-bit" RLE encoding which works best
when there are only three colors (and black) in a single line. Modify
the screenshot slightly to allow it to be encoded with fewer palette
updated.
2048 is a popular sliding block puzzle game in which tiles are combined
to make the number 2048.
It's one of the few games that are enjoyable to play on such a small
form factor.
This started as a port of a TkInter implementation of the 2048 game. I
implemented all of the TkInter APIs used by the game and it worked on
wasp-os without any code change in the game. However, the performance
was very poor and it consumed too much RAM. I have since reimplemented
the whole game from scratch and managed to achieve acceptable
performance, although more improvements could still be made.
Because names in Python can't start with numbers, I had some trouble
naming things. The module is called "ttfe" (two-thousand-forty-eight),
the class name is Play2048App, and the software.py entry is "Play 2048".

Currently wasp-os enables a narrow set of applications because we don't
want to consume RAM by importing the module and constructing the
application. We can improve on this situation by providing a small
(stateless) application that can be used to enable or diable applications.
This allows all the ROMed applications to be enabled using the GUI
without compromising on the ability to develop applications.
In fact this application significantlly reduces the RAM consumed in the
default case becasue the Self Test app does not need to maintain its
state.

The 2-bit RLE encoding, in addition to supporting colour is also fully
ROMable meaning we can save 32 bytes of RAM per image by switching to

Note: this requires all the clock PNG files to be reencoded (because
