// - Redo rendering code to *not* use Qt's transform functions, as they are tied
// to a left-handed system and we need a right-handed one. [DONE]
+// - Fixed length tool doesn't work on lines [DONE]
//
// STILL TO BE DONE:
//
// - Lots of stuff
// - Layer locking (hiding works)
+// - Fixed angle tool doesn't work on lines
+// - Make it so "dirty" flag reflects drawing state
//
// Uncomment this for debugging...
