between the current DPI and the platform's default DPI, with @ref
glfwGetWindowContentScale and @ref glfwGetMonitorContentScale.
Changes of the content scale of a window can be received with the window content
scale callback, set with @ref glfwSetWindowCloseCallback.

content scale will depend on which monitor the system considers the window to be
on.
If you wish to be notified when the content scale of a window changes, whether
because of a system setting change or because it was moved to a monitor with
a different scale, set a content scale callback.
@code
glfwSetWindowContentScaleCallback(window, window_content_scale_callback);

The callback function receives the new content scale of the window.
