I think I'm least likely to break something if I do this as explicitly
as possible rather than trying to figure out the right helper to put it
in once and for all. So just add some boilerplate to reset all state at
the start of each onpress1 handler. This seems like a good choice since
we aren't planning to add a lot more menus that would quadratically
explode the boilerplate.
In order to achieve this I'm forced to switch the default LÖVE blend
mode, which might not be a good trade-off. In particular, any use of the
alpha channel looks very different.
Even if I get rid of this commit, I'm learning how hard it's going to be
to support all possible blend modes in an app like this. So there are
some major limitations in the sorts of LÖVE programs that will be
possible.
