|
|
* History:
|
|
* Date By Reason
|
|
* ==== == ======
|
|
* 31-jan-95 craige split out of ddraw.c and enhanced
|
|
* 27-feb-95 craige new sync. macros
|
|
* 01-mar-95 craige Win95 mode stuff
|
|
* 19-mar-95 craige use HRESULTs
|
|
* 28-mar-95 craige made modeset work again
|
|
* 01-apr-95 craige happy fun joy updated header file
|
|
* 19-apr-95 craige check for invalid callback in EnumDisplayModes
|
|
* 14-may-95 craige allow BPP change; validate EnumDisplayModes modes
|
|
* 15-may-95 craige keep track of who changes the mode
|
|
* 02-jun-95 craige keep track of the mode set by a process
|
|
* 06-jun-95 craige added internal fn RestoreDisplayMode
|
|
* 11-jun-95 craige don't allow mode switch if surfaces locked
|
|
* 12-jun-95 craige new process list stuff
|
|
* 25-jun-95 craige one ddraw mutex
|
|
* 28-jun-95 craige ENTER_DDRAW at very start of fns
|
|
* 30-jun-95 craige turned off > 16bpp
|
|
* 01-jul-95 craige bug 106 - always went to last mode if mode not found
|
|
* 02-jul-95 craige RestoreDisplayMode needs to call HEL too
|
|
* 04-jul-95 craige YEEHAW: new driver struct; SEH
|
|
* 05-jul-95 craige crank up priority during mode change
|
|
* 13-jul-95 craige first step in mode set fix; made it work
|
|
* 19-jul-95 craige bug 189 - graphics mode change being ignored sometimes
|
|
* 20-jul-95 craige internal reorg to prevent thunking during modeset
|
|
* 22-jul-95 craige bug 216 - random hang switching bpp - fixed by
|
|
* using apps hwnd to hide things.
|
|
* bug 230 - unsupported starting modes
|
|
* 29-jul-95 toddla allways call HEL for SetMode for display driver
|
|
* 10-aug-95 toddla EnumDisplayModes changed to take a lp not a lplp
|
|
* 02-sep-95 craige bug 854: disable > 640x480 modes for rel 1
|
|
* 04-sep-95 craige bug 894: allow forcing of mode set
|
|
* 08-sep-95 craige bug 932: set preferred mode after RestoreDisplayMode
|
|
* 05-jan-96 kylej add interface structures
|
|
* 09-jan-96 kylej enable >640x480 modes for rel 2
|
|
* 27-feb-96 colinmc ensured that bits-per-pixel is always tested for
|
|
* when enumerating display modes and that enumeration
|
|
* always assumes you will be in exclusive mode when
|
|
* you actually do the mode switch
|
|
* 11-mar-96 jeffno Dynamic mode switch stuff for NT
|
|
* 24-mar-96 kylej Check modes with monitor profile
|
|
* 26-mar-96 jeffno Added ModeChangedOnENTERDDRAW
