[Rd] Postscript can be very slow in R 2.13-0

Viewing certain postscript files under R 2.13-0 is very slow, at least using GSview on my 64 bit Windows 7 system. To see this, compare how long it takes to display these two files (fast.ps was created by removing the /srgb stuff in .ps.prolog):



The code to produce the above two files is here:


This is not exactly a bug, but is it a known issue? The hack used to produce fast.ps above is fragile and not suitable for regular use. Is there a option to the postscript() function (or could one be added) that would sacrifice sRGB support for speed?
