main: initialize scale to '1'

Browse source 
This ensures we always have a valid (but possibly incorrect) scaling
value. This allows us to simplify code that uses the scale - it
doesn't have to verify the scale if valid.

Furthermore, since render_resize() is the function that actually
updates term->scale, make sure to call it *before* updating the
cursor (otherwise, the cursor will use the old scaling value).
