exportDlg: Don't use native file dialog (allow event-recorded tests)
hud: Removed code that checked underMouse() for mouse clicks to allow for auto-recorded event-based testing.
(This code didn't seem to be necessary, at least not on OSX.)
view3d: Delete QVTKOpenGLWidget before app shutdown to avoid 'invalid context' error:
"QGLContext::makeCurrent: Cannot make invalid context current"
tests: Fixed import issues in lazy_test.py
tiling: When displaying uncaught exceptions in the dirtyLayersWorker, use sys.excepthook()
(It's idiomatic, and allows test scripts to catch rendering and gui-thread exceptions with the same mechanism.)
ImageView2D: Provide initial values for ImageView2D.x and .y
RenderingManager: Release qvtk widget on app exit to avoid QGLContext error. See also: 3541b1dd9582b14ea51326d225e654f5bfb74f23
