I haven't tried, but I presume a 1000 high graphic area with the drawing
within that height will work, scaling to 40 denemo pixels high - a staff
height. I am not sure about the mirroring.
We could additionally do things at directive draw time (e.g. scaling)
and at directive load time, I am not sure about different load routines
- all possible, but we have to identify our needs first. The only things
relatively fixed are our use of librsvg to load the image (we would need
a good reason to start writing our own svg loader for cairo) which seems
to place (unknown) restrictions on the svg syntax (e.g. the transorm =
"scale(1,-1)" did not give joy).
