Revision: 1.13
Committed: 2001-07-03T19:20:45Z (22 years, 10 months ago) by cebix
Branch: MAIN
Changes since 1.12: +1 -0 lines
Log Message:
- improved compatibility of multiple depth/resolution handling with versions
  of MacOS before 7.6:
   - Apple mode IDs are now allocated contiguously from 0x80 (the video_*.cpp
     module must call video_init_depth_list() after adding all modes)
   - if the video driver didn't receive a GetVideoParameters call, it patches
     ScrnBase and the main GDevice upon a video mode switch (otherwise MacOS
     will continue to use the old frame buffer base)
   - the rowBytes values in the video parameters slot resources are correct
     for all bit depths
