Implement more of LdCanvas.
1. Add methods for coordinate translation between cairo/GtkWidget coordinates and LdDocument coordinates. 2. Draw the grid correctly (also make it significantly faster). 3. Place the canvas into a GtkScrolledWindow and register the set_scroll_adjustments signal in the GtkWidget base class. 4. Allow scrolling inside of an area of 200 x 200 units (for now). In the future, it should be possible to go to infinity.
