Přemysl Eric Janouch 616c49a505 Make a separate library. 
This is required for gtkdoc-scangobj. So far it's much like it's been
before, the main differences are that source files are in two directories
from now on and the build process has two stages.

Přemysl Eric Janouch 909a0352cc Don't draw the grid when it would be too narrow.

 2011-01-06 13:07:04 +01:00
Přemysl Eric Janouch 53d1de680d Change symbol clip tolerance to widget units.

Přemysl Eric Janouch d3e5483c84 Make adding symbols to the diagram possible.
