34785 7708 d 9 h murrell /trunk/ GEDevDesc *dd removed from GEcontourLines()
(as suggested by Barry Rowlingson)		  
33297 7826 d 18 h ripley /trunk/src/ tweak error messages  
32871 7853 d 1 h ripley /trunk/ mark messages  
32380 7881 d 19 h ripley /trunk/src/ add notes about compatibility with UTF-8
clarify on help pages nbytes/nchars differences		  
31938 7924 d 14 h murrell /trunk/src/ New recordGraphics() function for recording arbitrary code on the graphics engine
display list; intended to encapsulate calculate-then-draw operations

recordGraphics(), .Call.graphics(), .External.graphics, and traditional/base
graphics operations do not record when they are nested within each other.

Error/user-interrupt handling code performs some resetting of graphics engine
state.

grid drawDetails methods are recorded on graphics engine display list by default
(so will be rerun on device resize or copy between devices)		  
31216 7980 d 11 h /trunk/ Fixed test of lwd==NA in contour  
30980 8001 d 10 h murrell /trunk/src/main/ Fix to change default colour NA_INTEGER to R_TRANWHITE  
30129 8062 d 9 h murrell /trunk/src/ Added support for graphics engine font families in PDF device
Added support for alpha transparency in PDF device
Changed mapping of R-level NA colour to internal C-level colour:
was NA goes to NA_INTEGER
now NA goes to R_RGBA(255, 255, 255, 255) - transparent white
Plus some small grid patches

21061 8736 d 14 h murrell /trunk/src/main/ Separated out calculation of contour lines (from drawing of contour
lines and labels)		  
20377 8790 d 2 h ripley /trunk/ more tests for NA_STRING in graphics routines
