- Added native monitor handle access to native API
- Added `glfwSetDropCallback` and `GLFWdropfun` for receiving dropped files
- Added `empty` test program for verifying posting of empty events
- Bugfix: The debug context attribute was set from `GL_ARB_debug_output` even
when a debug context had not been requested
- Bugfix: The particles example was not linked against the threading library
