34864 7699 d 9 h murdoch /branches/R-noNULLenv/ ported r33596:34862 from main  
33359 7821 d 6 h murdoch /branches/R-noNULLenv/ Create no-NULL-environment branch  
33297 7825 d 5 h ripley /trunk/src/ tweak error messages  
32871 7851 d 12 h ripley /trunk/ mark messages  
32380 7880 d 6 h ripley /trunk/src/ add notes about compatibility with UTF-8
clarify on help pages nbytes/nchars differences		  
31938 7923 d 1 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 7978 d 22 h /trunk/ Fixed test of lwd==NA in contour  
30980 7999 d 21 h murrell /trunk/src/main/ Fix to change default colour NA_INTEGER to R_TRANWHITE  
30129 8060 d 20 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		  
29959 8071 d 2 h ripley /trunk/src/main/ remove debugging code  
29956 8071 d 6 h ripley /trunk/src/main/ fix array overruns, simpify code a bit.

27215 8281 d 20 h murrell /trunk/ Added contourLines() function
contourLines() and contour() use same C code to generate contour lines

21594 8680 d 21 h murrell /trunk/src/main/ Added "names" to result of contourLines  
21061 8735 d 1 h murrell /trunk/src/main/ Separated out calculation of contour lines (from drawing of contour
lines and labels)		  
20377 8788 d 13 h ripley /trunk/ more tests for NA_STRING in graphics routines
