Testing has demonstrated that del self.x does not make the memory used to
store x available for garbage collection.
There is clearly an additional reference from another place. In fact
*after* del self.x then the memory can be made available for GC by
assignment (e.g. self.x = None). However I haven't found how to release
this reference and there is nothing in self.__dict__ that can help.
For now we'll use a twp-step process where we set the variable to None
before deleting it.
This has a big impact on memory usage. For Software it is almost 1k
(a.k.a. about 10% impact on free RAM).

Currently the number of pages is (acidentally) hardcoded where it need
not be and the scroll directions aren't right as soon as we go beyond
two pages (where scroll up and down are equivalent actions).
Fix both.

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.
