pgf backend doesn't work well with very large numbers #1857
Description
When plotting data with very large values (in my use case I have around 10^55), the pgf backend produces files on which latex chokes saying:
! Number too big.

I can only go up to 2147483647='17777777777="7FFFFFFF,
so I'm using that number instead of yours.
From a quick look at the code, it apparrently just sets the clipping rectangle and just passes then numbers through otherwise. I suppose some clipping should happen in the backend itself.

@pwuertz : I haven't looked into this in depth, but thought I might provide a pointer: matplotlib does have algorithms to clip paths to a rectangle that may be useful here. See

Thanks for the hint mdboom!
@elenril: Does that patch fix the problem you are seeing or can you post an example that triggers the error?

@pwuertz thanks for the fix, it seems to work for me.
