background position erroneously set in ie7/8

[commonpike]

(this plugin is deprecated - this is just a warning for people who may want to use it anyway ..)

when setting background-position:center; in css, explorer returns a pixel value for backgroundPositionY in javascript(well, over here). pixel sizes are not supported by this plugin, and so the fake background position gets set way off, sometimes even offscreen.

so, dont say background-position:center :-)
