However, for the future (1.4.x), I think we should handle "white" and
"transparent" differently, and have bg default to "transparent" for
all devices. A quick look shows that this is would be easy, as only
24 bits of the rcolor type are used. So would there be an objections
to using a bit (or a single value) of the upper byte to denote
"transparent"? (Actually, Peter D has 0xffffffff in use as invalid,
but that's more bits than are needed.) For consistency "transparent"
should be an alternative...

o The entry points rgb2hsv and hsv2rgb have been migrated to
package grDevices and so are no longer available.
o R_GE_version has been increased to 10 and name2col removed (use
R_GE_str2col instead). R internal colour codes are now defined
using the typedef rcolor.
o The REPROTECT macro now checks that the protect index is valid.
o Several non-API entry points no longer used by R have been
removed, including the Fortran entry points chol, chol2inv, cg,
ch and rg, and the C entry points Brent_fmin, fft_factor and
fft_work.
