Re: Persistent load

This is really easy to do. Load the RsvgHandle from a file or wherever
you're getting it from. Then, use the rsvg-cairo.h header to render it
to a cairo_t. You can do arbitrary things to the cairo_t, like scale,
skew, rotate, and etc.

For example, if you'd like to load an image, and then render it at 2x
size, you might do something like the following pseudo-code:

// just load this once
rsvg = rsvg_handle_new_from_file(filename);

// inside of your draw()/expose() function
cr = gdk_cairo_create(gdk_drawable);
cr_scale(cr, scale_x, scale_y);
rsvg_cairo_render(cr, rsvg);

Best,
Dom
