TestGDVideo.c by Denis G. Pelli
Tests all the documented Control and Status calls implemented in GDVideo.c
The calls are documented in Designing Cards and Drivers, 3rd Edition.
The main purpose of this program is to find bugs in video drivers. If you do
find a bug that isn't already listed in the table at the end of “Video synch”
then please send it to denis@xp.psych.nyu.edu
Unfortunately, the most common way to discover a new bug is for this program to
crash. Please report crashes to denis@xp.psych.nyu.edu
BUGS:
HISTORY:
8/11/89 dgp wrote it
3/23/90 dgp introduced special case conditionals to skip tests known to crash
particular drivers.
3/23/90 dgp made it compatible with MPW C, as a tool.
3/24/90 dgp made some of the printouts less cryptic.
3/31/90 dgp introduced RestoreDeviceClut after SetMode call.
7/12/90 dgp tidied up the initial printf
7/19/90 dgp Renamed VideoTest.c
Open & close a window on each screen and DrawMenuBar()
so that QuickDraw will restore each screen.
7/28/90 dgp italicized name of book.
9/9/90 dgp Added quit by Command-. for graceful exit from bad situations.
10/17/90 dgp Removed unused variables. Replaced TRUE & FALSE by 1 & 0.
10/20/90 dgp Apple has renamed the control and status calls, so I followed suit:
GDGetPageBase replaces GDGetBaseAddr
GDReset replaces GDInit
GDGrayPage replace GDGrayScreen
GDGetPageCnt replaces GDGetPages
10/22/90 dgp Print out number of pages for all modes, not just current mode.
dgp Restore clut manually since RestoreDeviceClut() doesn't
work on NuVista.
10/28/90 dgp Only test GetInterrupt & SetInterrupt if System is 6.05 or higher. This
avoids SetInterrupt() crash on old Apple TFB video driver.
2/12/91 dgp Preceded GDGrayPage() call by GDSetMode() to cure crash when running
program immediately after rebooting. Mysterious.
Added SelectWindow() at end of program.
3/9/91 dgp Print out mode names.
4/15/91 dgp Make sure that new palette manager exists before calling RestoreDeviceClut.
Thanks to Chuck Stein for alerting me to the bug.
6/6/91 dgp Time and print out how long GDSetEntries takes.
8/24/91 dgp Made compatible with THINK C 5.0.
1/19/92 dgp Cosmetic improvements to the printout.
2/25/92 dgp Put timing info in bold.
8/22/92 dgp Display results of calling GDFrameRate() and GDFramesPerClutUpdate().
8/27/92 dgp replace SysEnvirons() by Gestalt()
12/17/92 dgp enhanced to work with any dac size.
12/30/92 dgp Use GDClutSize() to determine clut size.
1/6/93 dgp Tidied up the cscGetEntries/cscSetEntries code, now that we don't have
to test for the Mac IIci driver.
Skip cscGetEntries on Relax driver.
1/7/93 dgp 1.1 First numbered version.
1/18/93 dgp Renamed ModeName() to GDModeName().
1/18/93 dgp Moved the code that checked for bad drivers into GDGetEntries() in GDVideo.c,
where it belongs.
2/1/93 dgp Report whether driver is RAM- or ROM-based.
2/5/93 dgp 1.2. Recompiled with latest version of GDVideo, which now supports
patching of Mac IIci ROM-based driver.
2/6/93 dgp 1.3. Report ROM version, if driver is ROM-based.
2/7/93 dgp 1.4. Recompiled after fixing endless loop in PatchMacIIciVideoDriver
in GDVideo.c
2/18/93 dgp 1.5 Made compatible with PowerBook 160, by omitting call to GDSetInterrupt.
2/22/93 dgp 1.6 No longer assume that driver uses a version 0 gamma table.
4/17/93 dgp 1.7 Replaced obsolete GDFramesPerClutUpdate and GDTimeClutUpdate by
GDTimeClut.
7/7/93 dgp 1.8 A bit more error checking of GDGetGamma.
7/29/94 dgp Eliminated use of "#s" printf format, since it's not supported by
Metrowerks CodeWarrior C.
9/5/94 dgp removed assumption in printf's that int==short.
5/22/95 dgp fixed minor bug reported by Michael Pelikan:
systemVersion was never properly initialized.

For reasons that I don't understand, calling cscGrayPage() first,

a call to cscSetMode() cures the symptom. Later calls to cscGrayPage()
