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 direct callers of draw_pbar() can have 20 or more digits after
the decimal place. Fix this by moving the rounding function.

Currently there is a redundant fill operation issued for every character
drawn. This was added to draw the background colours correctly but the
change did not account for the optimized character rendering in
_draw_glyph().
This results in ~15% performance improvement for character rendering

The music player volume control uses up and down events, but in the
foreground function the app requests left and right events.

Currently, if the line wrapper attempts to break a line on a space and
that space character is outside the bounding box, then we generate an
over-long line.
Fix this by handling line break generation *after* we have checked the
length of the current line.
