Try GdkPixbuf. For rotation, I had to write my own code, but I think
that GdkPixbuf will scale a pixmap for you.

Use a small canvas -- viewport-sized -- and render your map on the fly.
There is a max size for windows, 32kx32k pixels. And, a huge pixmap will
eat up lots of memory. A small map, redrawn on the fly, may actually
perform better, and will certainly be easier on memory.
