Let me make a correction. Viewing the file should not take so long, but there 
is something strange going on that I dont understand. axes_demo_PS.ps 
actually takes almost a full minute to load on my computer if the new API is 
used (excuse my first incorrect report). What I see is that the blue line is 
immediately rendered, and then ghostscript seems to stall for 45 seconds, and 
then renders the rest of the file. If I comment out the blue line in the 
postscript file itself:

% gsave
% 446.4 345.6 72 43.2 clipbox
% [446.4 0 0 6920.64 72 159.326] concat
% 0 0.001725 m
[...]
% 9.999 -4.733e-05 l
% gsave 0.00224014 0.000144495 scale stroke grestore
% grestore

then the file will load immediately, with no pause. This is strange, I cant 
identify the source of the hangup.
