/*
 * File:	main.c
 *
 * This application is a test-bed of single frame tests for RDP
 * test vector generation. The idea is that each frame possibly uses a 
 * different dataset (see static.c) to render a particular test.
 *
 * Under argc, argv control, you can choose to run a single frame test, or
 * (by default) run all the "frames" of vector generation at once.  When
 * sending multiple "frames" down, we always wait for vertical retrace before
 * drawing the next frame (frames are always drawn in the first cfb, so that we
 * know how to extract the image data when running simulations/test vectors).
 *
 * At the user's option, they may specify that RDRAM (e.g. the frame buffer)
 * has been preinitialized, thus eliminating the need for a screen/zbuffer 
 * clear.  Use the -m flag when this is the case.
 *
 * A similar strategy was used in RDP verification, so we are leveraging
 * heavily from the old rdpverif program.
 *
 * The "-c <number>" flag performs checksum screen compares.
 *
 *     Use in conjunction with the -p to obtain a checksum dump ("printOnly").
 *
 * Use gload's -a flag to pass arguments through to this app.
 *
 * NOTE:
 *
 * This test-bed is composed of some shared code, and test-specific
 * code. To add or modify a test case, you should only touch the
 * test-specific code. Modifying shared code might break other tests, should
 * we ever create other directories of test vector generators based upon this
 * program.
 *
 *  FILES THAT MAY BE SHARED WITH OTHER TESTS: (don't modify)
 *
 *	main.c
 *	init.c
 *	dynamic.c
 *	zbuffer.c
 *	spec
 *
 *  FILES THAT ARE TEST-SPECIFIC: (may modify)
 *
 * 	<module_name>_static.c	(holds static display list data for tests)
 *	<module_name>.h		(exports info to main.c, etc.)
 * 	<module_name.c		(holds test frame procedures, etc.)
 *	<any related include files>	(textures, etc.)
 *	Makefile			(make test rules)
 *
 * A separate set of files should be modified when producing display lists for
 * per module testing (e.g. cs.h, cs.c, cs_static.c).  A template display list
 * test has been provided; some real gfx dl's are provided as samples in the ms
 * test series.
 *
 * TO ADD A TEST CASE:
 *
 * decide which module your test will focus on, then tweak:
 *
 * <module_name>.h		- extern the static display list, so that it is
 *				  visible from <module_name>_static.c
 *
 * <module_name>_static.c	- add the static display list for the test.
 *
 * <module_name>.c		- add the procedure to be called to
 *				  perform the test case. (also put it
 *				  in the testCaseProc table appropriate for
 *				  this module)
 *
 *				- put the static display list pointer
 *				  in the testList table (appropriately named
 *				  for your module under test) as a Gfx pointer 
 *				  in the GfxTest_t struct; also provide a name
 *				  for your test so that the rdpascii2rdp tool
 *				  can provide a filename for the resulting
 *				  binary .rdp file.
 *
 * ... plus add any new textures, include files, etc.
 *
 * All locations are marked with comments that say "ADD TEST CASE"
 * and give some hints what you need to do there.
 *
 * ADVANCED USAGE:
 * You could re-use test case procedures or data, as long as you
 * coordinate with all the tests that share it. It is a bad idea
 * to share data or procedures with a test that someone else may
 * go in and modify.
 *
 * If your test case needs a command line argument, that isn't handled
 * too cleanly. You would have to add it to main.c, and export the
 * global variables, etc. (messy) 
 *
 * This test suite favors single-frame tests. Animation support is clumsy.
