Thicker lines in draw mode

My guess would be that it was one of those "how could anyone want more than this" things. We often apply limits to avoid "programmers insanity". You know, you write code that computes a line thickness (for instance) and manage to divide by a very small number. You probably don't want a line thickness of 1000 points. But it can be tricky to find the right limit, and some of those limits are from 30 years ago when computer graphics were quite different!

So, what limit would you find to be reasonable? What are you trying to do? Maybe we can find a work-around until we can change the limit.
