------- Additional Comments from Zhenyao Mo <zmo at google.com>
The gl-uniform-array.html test is copied from WebGL conformance tests.

Have to fix some minor bugs to make the test green:
1) For a few functions, generate INVALID_OPERATION (instead of INVALID_VALUE)
if resource is from another context.
2) useProgram(null) should work in Safari.

Tested both Chromium and Safari in Mac.
