Should use a carraige return on the progress bar instead of a new line?

[johnbburg]

Currently the progress bar writes a new line for each incremental step of progress. It seems like the progress bar should be outputting a carraige return to overwrite the line instead. So:

Vs.

0% [ ============================== ] 100.00% (1.1s) 
>> Rasterization complete.

(With an effect of a bar filling up over time).

This can be easily done by changing to a carraige return /r instead of a new line here:

process.stdout.write(str + (hasTerminal ? '' : "\n"));
