Use EXPECT_DOUBLE_EQ

I'll give it a try, but we might not be able to do that.  At some point a while
ago, I did have a comment on this code that mentioned we need to check only for
float accuracy even though the matrix uses doubles - because some operations
that we compute transforms for started with floats.

I'm not sure what happened to that comment, I think it disappeared while people
were moving this code around different places.

I see. If it's a problem, keeping it as it has been is okay.
