I've got the user interface to pan and rotate an object, more or less works. [git-p4: depot-paths = "//depot/solvespace/": change = 1654]
and add some (non-functional) menus to the graphics window. Start to rough in some data structures to hold the sketch. No real work yet, though. [git-p4: depot-paths = "//depot/solvespace/": change = 1653]
