Tests to check user code cannot access uninitialized data from GL resources.

On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".

PASS Context created.

Reading an uninitialized texture (texImage2D) should succeed with all bytes set to 0.
PASS gl.checkFramebufferStatus(gl.FRAMEBUFFER) is gl.FRAMEBUFFER_COMPLETE
PASS All data initialized
PASS getError was expected value: NO_ERROR : 

Reading an uninitialized portion of a texture (copyTexImage2D) should succeed with all bytes set to 0.
PASS gl.checkFramebufferStatus(gl.FRAMEBUFFER) is gl.FRAMEBUFFER_COMPLETE
PASS getError was expected value: NO_ERROR :
