You are right. =20
It looks like the aspect ratio code is broken in
all of the cairo-based terminals including wxt.

Worse, I can't even see how it is _supposed_ to work.
Who/what/where is maintaining the values of=20
   term->xmax   and  term->ymax
   term->h_tic  and  term->v_tic ?
These are used to calculate aspect ratio, but I think the
cairo drivers are not setting them to useful values either
initially or when the window is resized.

I'm hoping Timoth=E9e can provide a simple fix.
