On most platforms, accessibility is either implemented or not implemented and this can be + discovered with SCI_GETACCESSIBILITY with + SCI_SETACCESSIBILITY performing no action. + On GTK+, there are storage and performance costs to accessibility, so it can be disabled + by calling SCI_SETACCESSIBILITY. +
