Re: Why floating point for widget positions

[Mike Emmel <mike emmel gmail com>]

If the data is useful then the motion event could be changed to have a
integer pixel part and floating point <1 part for subpixel position.
This floating point data is not read by 99.99999% of the apps written
for gtk.
