Description

First, here's the test case: http://www.redbrick.dcu.ie/~noel/blog/molecproc/fourcircles.html

In Firefox, you'll see four circles in a row (correct behaviour), but in IE you'll only see two in a row, and a third in the middle of nowhere. The problem seems to be handling of very small circles in IE. Applying a large scaling to a very small circle introduces some rounding error somehow.

Here's a comment by Tom Trenka: "The VML engine in IE doesn't like fractional numbers, and it looks to me like that's what's happening for you here, with your radii. Though it also looks like a couple of other things are in play--one being a set of missing parenthesis in a calculation, which breaks when the width of something is returned as 0 (it looks something like -l/w-0.5, and it should probably be -l/(w-0.5) )."

For me this bug is easy to workaround, but I thought I'd let you know.

BTW, it's usually better to attach test files to the bug so they are here permanently.
