ISSUE-2345: Last Call Comment: 15.17 feGaussianBlur

Last Call Comment: 15.17 feGaussianBlur

SVG 1.1 F2 Last Call
Raised by:
Erik Dahlström
Opened on:
it is nice to see, that the formula for the y dimension is
added for the feGaussianBlur.
Nice as well to get now the input image for standard deviation zero.

Minor cosmetic questions/suggestions:
a) Why is H(x) styled in black, I(y) in red?
b) Why is the approximation formula only for s available?
(should be sufficient to write, that the approximation applies
for the t correspondingly)
c) Maybe worth to mention, that for something like stdDeviation="1 0"
or stdDeviation="0 1" with '1' representing something different from
0, the mathematically expected result is not the input image.
It is only a blur in one direction.
However, because the definition does not explictly mention
this case, implementations will hopefully do it as mathematically

RESOLUTION: fix the styling, the approximation formula and mention the case with stdDeviation being 0 in one direction explicitly.
