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"’.

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.
Whatever that is ... Xlib perhaps?
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!
