Set `filterList` to a pointer to the start of the array of filter items and `filterCount` to the number of filter items in that array.  See the "File Filter Syntax" section below for details.

 - `defaultName`: (For SaveDialog only) Set this to the file name that should be pre-filled on the dialog.
 - `parentWindow`: Set this to the native window handle of the parent of this dialog.  See the "Usage with a Platform Abstraction Framework" section for details.  It is also possible to pass a handle even if you do not use a platform abstraction framework.
