[R] strange behaviour with rotated viewports in grid

[Rafael Najmanovich]

	Dear All,

	The issue I reported earlier seems to be restricted at least to Mac  
OSX GUI using 2.3.1. It does not occur in the Terminal in Mac OSX (R  
version 2.3.1) or in Linux (R version 2.2.1). I will separately send  
this to r-sig-mac.
	Best,
