So the insignia moves with the sprite can can be a different color for each spaceship. You may not get it depending on your hardware. Kyra only works for direct color modes.
Color depth can have a large impact on engine performance.
The results of the test will be dumped in the file testdata.txt. Useful for testing the speed of a machine and the effects of depth and fullscreen. Very useful for testing how changes to the code affect the framerate. Useful in conjunction with depth. Note that the first test is 0.
