[GRASS-dev] raster offset with cairo driver

[Hamish]

Hi,

raster offset and fonts now look ok, good stuff guys.

I've updated the fancy example on the wiki page to show off the fancy compass:
 http://grass.gdf-hannover.de/wiki/Cairo_driver#Examples


d.out.file now has added support for ps, svg, and pdf by way of the Cairo
driver.

but it doesn't work, I get output like this for the simple spearfish example:

$ cat spearfish.ps

also, is it possible for the Cairo driver in PS and PDF modes to respect
GRASS_LANDSCAPE and GRASS_PAPER like the GRASS PS driver?


thanks,
Hamish
