I have tested on octave -3.7.2+ (development snapshot on Feb 23).
(http://octave.1599824.n4.nabble.com/Octave-3-7-2-Windows-VS2010-available-td4650194.html)

>> graphics_toolkit fltk
>> scdraw
>> tic; print -dpdf scdraw.pdf; toc
Elapsed time is 2.06 seconds.

Speed of fltk printing seems to beimproved in the development source.
