Comment 1

[Kelsey Gilbert [:jgilbert]]

Some of this was fixed by the recent texture refactor, so pull a recent copy of central before starting on this.

Comment 2

[Ethan Lin[:ethlin]]

There is some error messages about shader: "Error compiling VERTEX_SHADER '[object WebGLShader]':ERROR: 0:1: '' :  #version required and missing.". After applying the attachment 8693246 [details] [diff] [review] in bug1207288, the problem is fixed and the test is passed.
So I set dependency to bug1207288.

All tests passed.
