[R-SIG-Mac] new raster image support in r-devel

[Simon Urbanek]

Oops, I was so focused on things breaking in SL that I missed that  
this one breaks on Leopard only :)
Anyway, yes, the exact same binary breaks on Leopard:

Reason: KERN_INVALID_ADDRESS at address: 0x168c8001
QuartzCocoa_Cap (dev=0x921d80, userInfo=0x9210f0) at ../../../../../../ 
R-devel/src/library/grDevices/src/qdCocoa.m:774
774	            rint[i] = ((screenData[i*4 + 2]) |
(gdb) bt

#2  0x00cab6dc in L_cap () at ../../../../../../R-devel/src/library/ 
grid/src/grid.c:2851


I'll nave a look after I'm done with the 2.10.1 release...

Cheers,
Simon
