[cairo] SVG & PS/EPS surfaces

[Tomas By]

But all the files (PS, PDF, SVG) are pixels, not vectors??

I create one surface (have tried all three types above) on which I draw, 
using lines/arcs.

Then I create a 2nd surface, and do (in C terms):

   cairo_set_source_surface(cr_of_2nd_surface,1st_surface,0,0);
   cairo_paint(cr_of_2nd_surface);

Have tried various combinations of surface types: SVG+PS, PS+PS, 
PDF+PDF, probably a couple more. All the resulting files, as far as I 
can tell, are raster not vector.

Using recording surface for #1 would seem to rule out the possibility 
that the pixellation happens already in the first step.

(The reason for two surfaces is that I want a smaller number of images 
that I then combine in the files.)
