do you mean rect_f.h?

Whoops, yes. Will fix

Is this related to this CL somehow or here by mistake?

[jamesr, 2014/07/07 19:37:25]

It's related - code that was doing comparisons between two RectFs was using
ToString() prior to this patch to both get pretty failure values and to round
(via the floating point formatting) into a string.  The callsite for this
actually has very slightly different RectFs that stringify to the same thing but
are not exactly the same number. This makes the fuzziness a bit more explicit
