Can I disable Cairo?

Mon, Jun 20, 2011 5:25 AM #

On Linux 2.13 by default links cairo, so png() uses it for rendering.
One of my users has performance problem, so ask if it possible to 
temporary disable cairo during png() rendering so it reverts to grGraphics.
My workaround for now is to configure R without cairo, but this affects 
all users that are forced to load and use CairoDevice if they wants 
better quality.
I want to avoid this, is it possible?
Thanks!

See the help page!

     type: character string, one of ?"Xlib"? or ?"quartz"? (some Mac OS
           X builds) or ?"cairo"?.  The latter will only be available if
           the system was compiled with support for cairo - otherwise
           ?"Xlib"? will be used.  The default is set by
           ?getOption("bitmapType")? - the ?out of the box? default is
           ?"quartz"? or ?"cairo"? where available, otherwise ?"Xlib"?.

Whatever that is ... Xlib perhaps?
