Fix goals
The "goals" section of the project description claims rsvg would try to be a low-footprint library.
As it is using the most heavy weight toolchain on earth (Rust), this does not match reality.
For example building the full XFce4 enviroment from source (from scratch) used to take a few hours (or maybe half a day on slower machines). It is now in the order of a week (if you are lucky).
Of course it helps if you are lucky and use a system/architecture the rust kids provide binaries for (and you trust those binaries, and those binaries work for you).
