Set the horizontal to -45, vertical 0 (set the horizontal to 45 to place the shadow behind).
Flip the image (image/flip)
Blur the image
go to image/normal filters/blur more. The blur is optional, in fact it may look better
without it.
Lay down the same text you did before
place it above the angled text (shadow) to make it look like text that is shadowed.
There is a couple of catches. Say you are making shadows for a word
like 'dog'. You will have to cut the shadow for the 'g', and paste a
little below the shadow for the d and o for it to look right. So
basically any characters with a stem that lies below the other letters
will have to be moved by cut and paste Which also means if you have a
'wild font' for lack of a better word, this effect could be fairly
taxing.
