container position=absolute seems to be off

[Randy Paries <ra...@unitnet.com>]

Hello,
 
i am working on an application that creates an .fo that represents a
page of labels
 
The problem is that is appears that the container position="absolute"
settings are correct, but each block container is off a little(i have
included example code below)
 
the first label should start 1/2 inches from the top and then each
label(block-container) should be an inch long.
 
it seems that the first box start 1/8" to long and the 1'
block-containers are actually 7/8's of an inch. So by the time we get
half way down the sheet the labels are all off.
 
I also tried a commercial FOP and it produces the same results.
thanks for any help , hints or suggestions
