[MiNT] SWM_REZCHANGE in shel_write()

shel_write() enhancements

-> Sh_wodex value 5   (Changed 9/29/92)

Request the AES to change resolution. The sh_wiscr's value affects
the meaning of sh_wisgr. If AES accepts the resolution change
request, then it will put the system in SHUT DOWN mode. An
application can either shut down and exit or deny to shut down by
sending a AP_TFAIL message to the AES.

a, If sh_wiscr is zero, then sh_wisgr is the physical device id to
   perform VDI's open physical workstation call. To get the current
   physical device id, do the Getres()+2.

   The following are the existing physical device id values:

   2 -> 320x200        ST Low
   3 -> 640x200        ST Medium
   4 -> 640x400        ST High
   6 -> 640x480        TT Medium
   8 -> 1280x960       TT High
   9 -> 320x480        TT Low

b, If sh_wiscr is one, then sh_wisgr is the video mode word for use
   in the FALCON030 machine. Sh_wiscr value from 2 and up are
   reserved for future use.

int16_t shel_write ( int16_t sh_wdoex, int16_t 
               sh_wisgr, int16_t sh_wiscr, int8_t *sh_wpcmd, int8_t 
               *sh_wptail );

N.AES have an extend mode

shel_write(5, vmode, falconflag, &ignorant, NULL)

ignorant is an integer. If shel_write returns null then you can find in
ignorant an App-ID from the programm with do not understand AP_TERM. If it
returns (ignorant) the value -1, then an Shutdown is started, -2 if some of the
parameters are wrong.

MagiC do it like MultiTOS.
