Software :: GIMP SVG Export Support?

It is a simple 2D RPG game. I have this great idea to use static backgrounds and foregrounds. To do this I plan to create another layer that will serve as the collision mask, and cover area where the player cannot move to. I have been trying to find a good format to do this, I want something simple because I plan to write my own library to read the format, it seems that most vector graphics formats are simple enough for that, so its not a huge issue, and not all the information is necessary, for my application, since it will not be visible, no color information is needed. However, there are not that many formats available, and they all seem to be XML based (I don't care for XML), but in the end, I settled on SVG. I wanted something I could create in GIMP, if these masks are too hard to create, I may never finish this project (laziness)... However, I discovered that my version of GIMP will not save as/export to SVG format! It will open SVG, but not export to SVG. Very frustrating. So I went through all the trouble of compiling GIMP 2.7, but that still doesn't support SVG. I made sure to install all libsvg-dev headers before building GIMP 2.7. What can I do to get GIMP to support exporting to SVG format OR is there another SIMPLE vector graphics format that GIMP supports that I could be using?
