* File dialog support. * File dialog support.
*
* SDL offers file dialogs, to let users select files with native GUI
* interfaces. There are "open" dialogs, "save" dialogs, and folder
* selection dialogs. The app can control some details, such as
* filtering to specific files, or whether multiple files can be selected by
* the user.
*
* Note that launching a file dialog is a non-blocking operation; control
* returns to the app immediately, and a callback is called later (possibly
* in another thread) when the user makes a choice.
