These are all keyboard tests. They read the whole keyboard state for each
test. This means that even you pressing an enter when starting this test is
enough to make it fail. I had to use something like 'sleep 2; make test'
when I was writing it.

I think errors with extra 046 message (WM_WINDOWPOSCHANGING) caused by not
processing all the messages after creating the window. I will try and use
extra message flushing from msg test.
