44288 6752 d 20 h ripley /trunk/src/ don't use opaque pointer for GEDevDesc internally in R

split out color stuff to Colors.h		  
44142 6759 d 10 h ripley /trunk/src/ A little re-organization to start moving towards making plot/graphics/base
solely the base graphics system. In paticular, calls from grid are now in
other files.
Colour handling has been moved from graphics.c to colors.c, and
device-handing split out into devices.c.
The header files reflect these changes.		  
44036 6766 d 19 h ripley /trunk/src/main/ forgot one static  
44035 6766 d 19 h ripley /trunk/src/main/ forgot one static

43932 6773 d 6 h ripley /trunk/src/ move re-encoding of graphics text to engine/vfonts level.
This allows Hershey Latin-1 to work in other 8-bit locales.
