tspan positioning seems strange in batik
Hi All,
I have 2 tspan elements in some SVG. The word following is split between the
2 and Batik renders the w on top of the "follo" text. The x coordinates of
the 2 characters are spaced quite far apart compared to other characters so
why does this happen??
<tspan x="0 7.9157 14.032 16.428 22.544 28.042 33.54 37.668 43.785 46.909
53.025 59.141 62.862 70.656 73.052 78.55 84.688 88.651 94.767 100.88 104.01
110.12 116.24 120.2 122.6 128.72 132.68 135.79 141.91 144.3 149.8 153.79
159.9 166.02 168.42 170.81 176.31 181.73 184.85 188.82 191.94 198.06 204.17
208.14 211.37 217.49 219.88 222.28" y="141.26" class="ps00 ps222">Unless
otherwise noted in this policy, the follo</tspan>
<tspan x="228.4 236.19" y="141.26" class="ps00 ps223">w-</tspan>
This odd behaviour doesn't happen in inkscape. I hvae attached a cut down
SVG that contains the above 2 tspans and very little else and screenshots of
Batik versus Inkscape rendering.
Any hints on the cause of this behaviour would be very much appreciated.
Thanks,

UPDATE2:
It appears I was a bit hasty in my previous reply. Only letter spacing is
negative and that doesn't seem to be the cause of the problem. Its the word
spacing on the first tspan. I guess when word-spacing is applied the first
tspan takes up more room and therefore overlaps the start of the second
tspan. But the bit I'm still not clear on is why this is happening when each
character is absolutely positioned using x coordinates.
Thanks,
Chris

UPDATE:
The CSS used in this SVG has negative word and letter spacing. Removing it
appears to resolve the problem. The actual numbers for letter and word
spacing are very small (<1) so I wouldn't expect this to have such a
dramatic effect on the text position.
