This adds a function for querying the current title of a window. This
currently returns a copy of the last title set via GLFW.
Fixes#1448Closes#1909Closes#2482
- Button label reflects window mode
- Window attention request button
- Slightly less bad button layout possibly
- Applicable button labels list expected delay
- Less telegraphic message for positions being unsupported
- Window size more likely to fit contents
This updates to a newer version of glad2 and switches to the header-only
variant.
This also (finally) switches to the newer glad2 loader signature that
allows us to pass in glfwGetInstanceProcAddress directly.
