Add support for browsers with subpixel accuracy
Add support for browsers with subpixel accuracy

Before the 3.0.0 release jQuery rounded the height to the nearest
integer, so the height returned by jQuery is not the correct value in
browsers with subpixel accuracy (positions and sizes with decimal
values), like Firefox. Due to this all the height related functions of
jQuery need to be replaced with custom versions that return the height
as a float instead of an integer.
