-/**
- * Test glDrawPixels(GL_DEPTH_COMPONENT)
- *
- * We load a window-sized buffer of Z values so that Z=1 at the top and
- * Z=0 at the bottom (and interpolate between).
- * We draw that image into the Z buffer, then draw an ordinary cube.
- * The bottom part of the cube should be "clipped" where the cube fails
- * the Z test.
- *
- * Press 'd' to view the Z buffer as a grayscale image.
