It was.. it has been added to the PCLOS repos after going through Tex

Now don't get me wrong though... the .svg filters are there, and you can import, but there is no functionality to gradients, or transparencies..
Basically you can take layers apart but not right down to those features so, if you have an svg with a gradient / transparency... it will be just one object with no layers.

This is all the same as always... and might be long to resolve (if ever)
Aside from this... xaralx is a very nice, fully functioning app (as far as it's intended first basic use using the .xar format)
If it never provides full integration with .svg it is still a wonderful app on it's own and a great contribution to the Linux Community

What's difficult, is when the moment anyone sees the word .svg mentioned along with xaralx... they assume this means it is functional and then when it is not, they begin a quest to make posts about how it does not without ever reading up on the entire tale... and eventually, xaralx gets a bad / negative rap.... and unjustly so... xaralx is still a great app, even without a functioning .svg support
The biggest thing to drive devs off and keep them from doing more is the amount of whining from the Linux users that this svg does not work....
.xar and .svg are two completely separate formats.... much as you cannot make a pc run with a mac processor, etc. (same theory and reality... just on a different level)
