This test ensures WebGL implementations handle uniformMatrix in a OpenGL ES 2.0 spec compliant way On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE". Checking gl.uniformMatrix. PASS should fail with insufficient array size for uniformMatrix2fv PASS can call uniformMatrix2fvwith transpose = false PASS uniformMatrix2fv should return INVALID_VALUE with transpose = true PASS should fail with insufficient array size for uniformMatrix3fv PASS can call uniformMatrix3fvwith transpose = false PASS uniformMatrix3fv should return INVALID_VALUE with transpose = true PASS should fail with insufficient array size for uniformMatrix4fv PASS can call uniformMatrix4fvwith transpose = false PASS uniformMatrix4fv should return INVALID_VALUE with transpose = true PASS successfullyParsed is true TEST COMPLETE
