Checks that a GPU status check failure will lose the context.
NOTE: This only passes in the test harness because it requires Internals.


Test drawArrays.

Do five 'safe' drawArrays.
PASS gl.isContextLost() is false
PASS gl.getError() is gl.NO_ERROR
PASS gl.isContextLost() is false
PASS gl.getError() is gl.NO_ERROR
PASS gl.isContextLost() is false
PASS gl.getError() is gl.NO_ERROR
PASS gl.isContextLost() is false
PASS gl.getError() is gl.NO_ERROR
PASS gl.isContextLost() is false
PASS gl.getError() is gl.NO_ERROR
Now force failure after the next drawArrays.
FAIL gl.isContextLost() should be true. Was false.
FAIL gl.getError() should be 37442. Was 0.

Test drawElements.

Do two 'safe' drawElements.
PASS gl.isContextLost() is false
PASS gl.getError() is gl.NO_ERROR
PASS gl.isContextLost() is false
PASS gl.getError() is gl.NO_ERROR
Now force failure after the next drawElements.
FAIL gl.isContextLost() should be true. Was false.
FAIL gl.getError() should be 37442. Was 0.

Test drawArraysInstanced.

Do four 'safe' drawArraysInstancedANGLE.
PASS gl.isContextLost() is false
PASS gl.getError() is gl.NO_ERROR

PASS gl.getError() is gl.NO_ERROR
PASS gl.isContextLost() is false
PASS gl.getError() is gl.NO_ERROR
PASS gl.isContextLost() is false
PASS gl.getError() is gl.NO_ERROR
Now force failure after the next drawArraysInstancedANGLE.
FAIL gl.isContextLost() should be true. Was false.
FAIL gl.getError() should be 37442. Was 0.

Test drawElementsInstanced.

Do seven 'safe' drawElementsInstancedANGLE.

PASS gl.getError() is gl.NO_ERROR
PASS gl.isContextLost() is false
PASS gl.getError() is gl.NO_ERROR
PASS gl.isContextLost() is false
PASS gl.getError() is gl.NO_ERROR
Now force failure after the next drawElementsInstancedANGLE.
FAIL gl.isContextLost() should be true. Was false.
FAIL gl.getError() should be 37442. Was 0.
