If you can spare the time...

Here is a small diagnostic patch for the qt terminal.
It tests the hypothesis that qt connection failure on Cygwin is due to
horribly slow font initialization.  With the patch in place font handling
is disabled until the first plot has completed.

This is guaranteed to mess up layout of the first plot, but if it makes
the connection succeed we can sort out font initialization later.
