 * This function recognizes a few "global parameters".  These are variables
 * which, if set to TRUE before calling this function, will have an effect
 * on this function, and which are always reset to FALSE by this function
 * before this function returns.  Thus they function just like normal
 * parameters, except that most calls to this function can ignore them.
 *
 * If "inkey_xtra" is TRUE, then all pending keypresses will be flushed,
 * and any macro processing in progress will be aborted.  This flag is
 * set by the "flush()" function, which does not actually flush anything
 * itself, but rather, triggers delayed input flushing via "inkey_xtra".
 *
 * If "inkey_scan" is TRUE, then we will immediately return "zero" if no
 * keypress is available, instead of waiting for a keypress.
 *
 * If "inkey_base" is TRUE, then all macro processing will be bypassed.
 * If "inkey_base" and "inkey_scan" are both TRUE, then this function will
 * not return immediately, but will wait for a keypress for as long as the
 * normal macro matching code would, allowing the direct entry of macro
 * triggers.  The "inkey_base" flag is extremely dangerous!
 *
 * If "inkey_flag" is TRUE, then we will assume that we are waiting for a
 * normal command, and we will only show the cursor if "hilite_player" is
 * TRUE (or if the player is in a store), instead of always showing the
 * cursor.  The various "main-xxx.c" files should avoid saving the game
 * in response to a "menu item" request unless "inkey_flag" is TRUE, to
 * prevent savefile corruption.
 *
 * If we are waiting for a keypress, and no keypress is ready, then we will
 * refresh (once) the window which was active when this function was called.
 *
 * Note that "back-quote" is automatically converted into "escape" for
 * convenience on machines with no "escape" key.  This is done after the
 * macro matching, so the user can still make a macro for "backquote".
 *
 * Note the special handling of "ascii 30" (ctrl-caret, aka ctrl-shift-six)
 * and "ascii 31" (ctrl-underscore, aka ctrl-shift-minus), which are used to
 * provide support for simple keyboard "macros".  These keys are so strange
 * that their loss as normal keys will probably be noticed by nobody.  The
 * "ascii 30" key is used to indicate the "end" of a macro action, which
 * allows recursive macros to be avoided.  The "ascii 31" key is used by
 * some of the "main-xxx.c" files to introduce macro trigger sequences.
 *
 * If "angband_term[0]" is not active, we will make it active during this
 * function, so that the various "main-xxx.c" files can assume that input
 * is only requested (via "Term_inkey()") when "angband_term[0]" is active.
 *
 * Mega-Hack -- This function is used as the entry point for clearing the
 * "signal_count" variable, and of the "character_saved" variable.
 *
 * Hack -- Note the use of "inkey_next" to allow "keymaps" to be processed.
 *
 * Mega-Hack -- Note the use of "inkey_hack" to allow the "Borg" to steal
 * control of the keyboard from the user.
 *
 * Note the nasty code used to process the "inkey_base" flag, which allows
 * various "macro triggers" to be entered as normal key-sequences, with the
 * appropriate timing constraints, but without actually matching against any
 * macro sequences.  Most of the nastiness is to handle "ascii 28" (see below).
 *
 * The "ascii 28" code is a complete hack, used to allow "default actions"
 * to be associated with a given keypress, and used only by the X11 module,
 * it may or may not actually work.  The theory is that a keypress can send
 * a special sequence, consisting of a "macro trigger" plus a "default action",
 * with the "default action" surrounded by "ascii 28" symbols.  Then, when that
 * key is pressed, if the trigger matches any macro, the correct action will be
 * executed, and the "strip default action" code will remove the "default action"
 * from the keypress queue, while if it does not match, the trigger itself will
 * be stripped, and then the "ascii 28" symbols will be stripped as well, leaving
 * the "default action" keys in the "key queue".  Again, this may not work.

 *  A large value (i.e. 100) would draw air tiles with large tracers,
 *  as tiles will "hang" in the air for quite some time. A small
 *  value (i.e. 1 or 2) will make them much more flickerish.
 *
 * Feel free to play around with this (AIR_FADE_THRESHOLD define, see also
 * "recv_air()" in net-client.c)
 *
 * Note: when "air tiles" are used to display projectiles which actually land
 * and then appear on the ground (i.e. arrows, thrown items), the final
 * tile is drawn BEFORE any of the air tiles have a chance to appear/fade.
 *
 * Note: *In theory* main-xxx ports might feel that they can handle the air
 * layer by themselves and more gracefully (e.g. with alpha blendend fades).
 * If you're working on this, and the direct Term_draw writes are too
 * intrusive for you, set global variable "air_refresh" to FALSE.
 * To disable this code completely, set "air_updates" to FALSE.
 *
 * Note: this function uses up the static_timer(2). This means you can't use
 * static_timer(2) anywhere else from now on.
 *
 * Note: this function probably breaks graphics mode in some way. Untested.
