38822 7293 d 11 h ripley /branches/C-link/ Create C-link  
38705 7304 d 16 h ripley /trunk/src/ remove some unused entry points, take others static.
add prefixes to graphapp and some graphics entry points
improve the use of / <--> \ conversions under Windows		  
36820 7524 d 5 h ripley /trunk/ update FSF address  
36748 7528 d 21 h murrell /trunk/src/ Added 'repEnds' arg to grid.xspline()  
36366 7558 d 22 h murrell /trunk/src/ Added widthDetails and heightDetails for grid xsplines  
36362 7559 d 0 h murrell /trunk/ Added 'arrow' argument to line-related grid primitives as new way to
specify
arrow heads on either end of line.

Deprecated grid.arrows().

Outlawed NA's in control points for an x-spline primitive.		  
36317 7560 d 22 h murrell /trunk/src/ Added X-spline primitive to graphics engine AND to grid  
36203 7568 d 8 h ripley /trunk/ add length-checking for the 'family' graphics parameter, and boost to 200 chars  
34785 7706 d 20 h murrell /trunk/ GEDevDesc *dd removed from GEcontourLines()
(as suggested by Barry Rowlingson)		  
34747 7710 d 11 h ripley /trunk/src/include/R_ext/ add include guards
allow to be used from C++ (where public)		  
32815 7853 d 21 h murrell /trunk/src/ Added graphics engine API version  
31994 7917 d 20 h murrell /trunk/src/ new "warn" and "wrap" arguments for grid.grab()

new grid.grabExpr() function

new GEnullDevice function		  
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)		  
30956 8000 d 22 h murrell /trunk/ Five new par()s:
'family' for specifying device-independent font family
'lend', 'join', 'mitre' for controlling line end/joins
'lheight' for controlling vertical spacing of multi-line text		  
30925 8001 d 22 h murrell /trunk/ Added line end/join/mitre support to:
(i) graphics engine
(ii) PostScript, PDF, and X11 devices
(iii) grid		  
30832 8007 d 21 h murrell /trunk/src/ Fix to remove lingering dependency of grid on base graphics
Graphics engine now keeps track of whether a device is dirty and
individual graphics systems can keep track separately of whether they
have dirtied the device.
Base only checks validity of device if it has dirtied the device.		  
29921 8073 d 6 h ripley /trunk/src/include/R_ext/ add copyright declarations and comments as to purpose.  
27236 8279 d 1 h murrell /trunk/src/ Merging R-gcontext branch  
21060 8735 d 1 h murrell /trunk/src/include/R_ext/ vfont calls moved into graphics engine
GEcontourLines added to graphics engine		  
19966 8818 d 6 h duncan /trunk/src/include/R_ext/ Filled out the definition for GEcallback using forward declarations of the GEDevDesc struct.
