To add more SVG support is great.  Not the least because ODF 1.2 recommends 
pixmaps to always be PNG and vector images to always be SVG.

You might be interested to know that there is a branch called libs-
unavail_save-ingwa that has some code that adds the ability to create object 
replacement images in SVG format to frame shapes.  It also contains support 
for the unavail shape to show these object replacement SVG images.

The reason why I haven't put this to review yet is that I had merge conflicts 
that led to an irritating saving bug that makes OOo unable to read our objects 
back.
