This was made using one span with blur and then another one atop of it.
Same tecnique as above but both have alpha filters added.
First I added a mask() to remove the inside, then a shadow() was added. Since there is nothing inside the shadow
is displayed inside. Then I removed the mask using chroma(). Before this I added the same text with a white color and
the second text was moved above this using position: relative; left: -200px;
You could just add glow but it looks better if the glowing is placed on the inside. To do this
you add mask, glow and chroma.
