Crash on vertical straight connectors.

[GoogleCodeExporter]

I seem to be having a problem printing labels on STRAIGHT plumb connectors 
that point perfectly down:

Error: uncaught exception: [Exception... "An invalid or illegal string was 
specified"  code: "12" nsresult: "0x8053000c (NS_ERROR_DOM_SYNTAX_ERR)"  
location: "http://tar.neothinktank.net/scripts/jquery.jsPlumb-1.2.5-all.js
Line: 2922"]

This is because in the case of perfectly vertical straight lines, ctx.y will 
be positive or negative INFINITY. Some check for this case should be made to 
prevent crashes in this case.

What steps will reproduce the problem?
1. Create any STRAIGHT connector that points perfectly down.
2. Make sure that connector has a label.
3. Boom

What version of the product are you using? On what browser and OS?
jsplumb 1.2.5 on Linux Firefox 3.5.16.

Please provide any additional information below.

hello, I have the same problem.
I solve it by add after line @2358 : if (_m == Infinity) _m=0;
I attach file with patch.

turns out that setting the gradient to zero if it was infinity caused other 
bugs.  i've fixed this for real now. it will be in 1.2.6.
