allow creation on remote (X11) displays

GLFW has a number of platform specific hints already, so a PR for this would likely be acceptable.

i'm aware that currently glfw maintains a global display for all its windows....

given the above, should a PR try to keep the current behavior (so selecting a display can only be done before the first window is created) or maintain a display for each window (which might get tricky if the different displays have different capabilities).

i tend towards the former, but then I think the proper function would be glfwInitHintString() (which does not exist yet!).

(note that i haven't checked the code recently, so i might have gotten things wrong)

Out of interest can you rework the application to call init after changing the DISPLAY environment variable?

A change to add per window displays would be pretty large, since the GLFW init uses the display variable to initialize a large number of variables used by all the systems in GLFW. So if a change to add this as an init hint would work for your use case then I think this would be the best way to go.

probably.

so do I understand correctly, that a PR should add a new glfwInitHintString() function (because the existing glfwInitHint() cannot take strings and is therefore not sufficient)

Yes, a new function glfwInitHintString(int hint, const char* value) similar to glfwWindowHintString(int hint, const char* value) looks like the way to do this.
