Some problems with Draft Mode and Screen-based Linetypes

* Draft mode should hide hatches, as the description implies. But I see that's not the case.

Steps to reproduce:

- Draw a rectangle
- Add a hatch to it (a pattern)
- Select draft mode (the hatch is still there)

* In Screen-based Linetypes mode, the description says that lines are drawn as 1 bit width.

The problem is that with a line of 0.5mm, lines are drawed thicker than 0.18mm while in this mode.

Thanks. I will update the manual accordingly.

In the latest version, hatches are always shown unless they take longer than a configured timeout to render.
Screen based line weights are calculated to show approximately right on the screen, i.e. a 1mm thick line is indeed displayed double as thick as a 0.5mm thick line.

So I'm testing this, I've drawn a 100mm x 100mm square and hatched it (ANSI37), how do I set the timeout so that when in draft mode my hatch isn't shown?

I've tried all sorts of numbers, please explain how to do this, although I could just turn off a layer it would be useful to know how to use this 'timeout' option properly :wink: .

The time out is present to make sure the computer does not hang if you set the scale to a low value.

That's definitely the way to go.
