func CompareOutputImages

func CompareOutputImages(testname string, t *testing.T)

CompareOutputImages is a utility method used by the graphics modules to compare output of tests with expected output.

FileAreEqual returns true if the two given files are the same. It does this by calculating the md5 checksum of each file and comparing. If either of the files does not exist, this returns false, and an error.

func FloatsAreEqual

func FloatsAreEqual(x, y float64) bool

FloatsAreEqual returns true if the two given float64 values are within Delta from each other.
