982 Create and bind a framebuffer object with a floating-point depth
983 buffer attachment. Make sure depth clamping is disabled. The best
984 steps for verifying the correct depth mode:
986 - Clear the depth buffer to 0.5.
990 - Read back the floating-point depth buffer with ReadPixels
992 clipped and those coordinates from 0.0 to 1.0 update the depth
1166 //Clear the depth buffer to 0.5.
1208 //Read back the floating-point depth buffer with ReadPixels
1210 // clipped and those coordinates from 0.0 to 1.0 update the depth
1299 Do the same as above, but use the default NEGATIVE_ONE_TO_ONE depth mode:
1301 - Clear the depth buffer to 0.5.
1305 - Read back the floating-point depth buffer with ReadPixels
1306 - Verify that no pixels are clipped and the depth buffer contains
1354 //Clear the depth buffer to 0.5.
1396 //Read back the floating-point depth buffer with ReadPixels
1398 // clipped and those coordinates from 0.0 to 1.0 update the depth
