I am studying how grass is made in the standard package and I would like more information on why the grass.psd ( and all other similar textures in other resources) have one layer with the edge bleeding few dozens of pixel?
Why is that and if this is necessary, what is the technic or photoshop filter to achieve this?

This filter is an edge dilation filter, probably Solidify by Flaming Pear (available from this page as part of the free plugin package.)
Edge dilation prevents fringing on alpha blended materials. Fringing is when linear interpolation causes the colour of transparent pixels to be visible at the edges of opaque areas. It is usually white, and looks like something has been crudely cut out of a magazine.
