Přemysl Eric Janouch 3419680f25 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.

Přemysl Eric Janouch efc3ad6f5c Implemented a skeleton of LdCanvas. 
It now paints itself white and draws a simple grid.
Also an LdDocument can be assigned to it.

Přemysl Eric Janouch 354e54826f Changed the object prefix from "logdiag" to "ld". 
It was just too long to type and read. My mistake.

Also a little change in CMakeLists.txt.

The next commit is going to change the object prefix.
