[Lorensen, William E (GE, Research)]

I agree. It looks great. After tomorrow's t-con sounds right.

Bill,

The Dashboard is not looking too bad today.

What do you think if we attempt to tag tomorrow ?

maybe just after the tcon ?

	Folks,
	
	Fisrt of all, this is not critical for the release.
	
	I was tracing down some test failues on windows vs70 and vs71.
There are
	three related tests that are failing:
	
	itkInterpolateTest, ResampleImageFilter3Test1 and 
	ResampleImageFilter9Test.
	
	Vnl_math_rnd uses assember code to round floating point numbers
for some
	windows compilers. Apparently, these round up on .5 rather than
rounding
	down. I temporary replaced the vnl_math_rnd call in
itkImageFunction 
	with a C version and all of the three tests passed.
	
	We should look at this after the release. It only affecte
nearest
	neighborhood calculations.
