// One might call this a Commdlg test jig. Its sole function in life
// is to call the Commdlg Common Dialogs; at present it doesn't even
// do anything horribly interesting with the results.
// Ideally it would also do event logging and be a bit less stupid
// about displaying the results of the various requesters. But hey,

// This structure is to set up flag / control associations for the custom
// requesters. The ft_id is the id for the control (usually generated
// by the system) and the ft_bit is the flag bit which goes into the
// settings longword for the various Commdlg structures. It is assumed
// that all flags fit in an unsigned long and that all bits are in fact
// one bit.
// The array of entries is terminated by {IDOK, 0}; the assumption is that
// IDOK would never be associated with a dialogbox control (since it's
// usually the ID of the OK button}.
