// Settings constructor: sizes the arrays to 2 growing in 2s, to save some
// memory (the default grow factor is 8, but we only need 2). It also
// initialises the DeviceInfo and DeviceCombo position indices, and defaults
// to Windowed, but notice that we will not get any meaningful values until
// the settings get initialised by the CXD3D class; the values will just
// save an access violation.
