Patch: fix segfault from empty raster
...ummary2d()
This reliably causes a segmentation fault. sessionInfo() below.
What's happening is that (for reasons which I'll discuss with the
ggplot2 developers) the 'colorbar' guide is being built with a zero-size
source raster.
In L_raster() (grid.c), this raster is not a "nativeRaster", so we do
image = (unsigned int*) R_alloc(n, sizeof(unsigned int));
with n = 0, and R_alloc() gives us a NULL pointer.
The display of this raster requests interpolation, so we end up in
R_GE_rasterInterpolate(), where 'sraster' is NULL, and chaos ensues as
it tries to read so...

R 2.12.1 is released
...2.12.x a warning will be
issued, but this will be correctly reported as an error in later
releases. (Reported by Charles Berry.)
? Fix for subsetting of "raster" objects when only one of i or j is
specified.
? grid.raster() in package grid did not accept "nativeRaster"
objects (like rasterImage() does).
? Rendering raster images in PDF output was resetting the clipping
region.
? Rendering of raster images on Cairo X11 device was wrong,
particularly when a small image was being scaled up using
interpolation.
